    PMID: 32675937 DOI: 10.3897/BDJ.8.e54748
    Background: An up-to-date checklist of the Peninsular Malaysian marine Anthuroidea is presented, based on previous taxonomic or ecological literature and recent collections. The present study, a part of the subproject on the Biodiversity of Sultan Iskandar Marine Park, recognised 24 species in 12 genera and 5 families from Peninsular Malaysia. An extensive list of bibliographical references, detailed information on habitat and distributional records, museum locations of type material are provided for each species. Amongst the listed species, 11 are recently discovered Malaysian species belonging to the genera Amakusanthura Nunomura, 1977, Apanthura Stebbing, 1900, Expanathura Wägele, 1981, Leptanthura G. O. Sars, 1897, Kupellonura Barnard, 1925, Pendanthura Menzies & Glynn, 1968 and Tinggianthura Chew, Rahim & bin Haji Ross, 2014. Our records were limited to shallow subtidal reefs of peninsular Malaysian coast, suggesting that the number of species in the list may rise with an extensive survey.

    New information: The up-to-date checklist of marine Anthuroidea of the Peninsular Malaysia comprises 24 species in 12 genera and 5 families, including some new distributional data.

  2. First documentation on herpetofauna diversity in Gunung Belumut Amenity Forest, Peninsular Malaysia: Implications for conservation in an Environmentally Sensitive Area (ESA)
    Ramli FF, Munian K, Mahyudin NAA, Othman N, Haris H, Abdullah-Fauzi NAF, et al.

    Malaysia is blessed with lush tropical rainforests that harbour an exceptional diversity of amphibians and reptiles. However, compared to other animal groups, amphibians and reptiles have received limited attention in research, despite their ecological significance. With amphibians and reptile species having been declining rapidly due to anthropogenic activities, there is a pressing need to conserve these species and their habitats. Environmentally Sensitive Areas (ESAs) are designated regions that are beneficial due to their critical role in providing essential ecosystem services and serving as repositories of biodiversity. Nonetheless, the classification of ESAs in Malaysia lacks biological elements and only focuses on physical attributes. To enhance the current ESA classification framework by integrating biological components, there is an urgent need to obtain information on diversity and habitat in Malaysia. Therefore, the objectives of this study were twofold: to determine the diversity of amphibians and reptiles in Gunung Belumut Amenity Forest and to conduct a comparative analysis between the herpetofauna assemblages in Gunung Belumut with other forest reserves in Peninsular Malaysia. The survey was carried out between March and June 2022, with additional sampling conducted in February 2023. The Visual Encounter Survey (VES) and pitfall trap methods were employed to survey the herpetofauna species, focusing on both aquatic and terrestrial habitats within the study area. A total of 210 individuals representing 38 species of herpetofauna were recorded, comprising 18 amphibian and 20 reptile species. Amongst the observed species, Limnonectesblythii was the most frequently encountered amphibian, with 59 individuals observed, while the dominant reptile species was Cyrtodactylusconsobrinus, represented by eight individuals. This pioneering study serves as a vital baseline documentation of the amphibian and reptile assemblages in Gunung Belumut Amenity Forest. It provides valuable information for identifying extant herpetofauna species, including those of potential conservation concern or rarity. These findings contribute to ongoing conservation efforts dedicated to the preservation of herpetofauna within the region. By understanding the diversity and distribution patterns of amphibians and reptiles in Gunung Belumut, effective conservation strategies can be developed to protect these species and their habitats.
  3. Fulltext Zooplankton species composition and diversity in the seagrass habitat of Lawas, Sarawak, Malaysia
    Ismail J, Mustafa Kamal AH, Idris MH, Amin SMN, Hamli H, Sien LS, et al.
    Biodivers Data J, 2021;9:e67449.
    PMID: 34177311 DOI: 10.3897/BDJ.9.e67449
    Seagrass habitats are considered to be some of the most biodiverse ecosystems on the planet and safeguard some ecologically and economically important fauna, amongst which are some globally threatened species, including dugong. Malaysian seagrass ecosystems are not widespread, but their existence supports some significant marine fauna. A rigorous zooplankton study was conducted from May 2016 to February 2017, in the seagrass habitat of Lawas, Sarawak, Malaysia, to examine their temporal composition and diversity, together with their ecological influences. A total of 45 zooplankton species from 13 significant groups were recorded in the seagrass habitat. The population density of zooplankton ranged between 2,482 ind/m³ and 22,670 ind/m³ over three different seasons. A single zooplankton copepod was found to be dominant (47.40%), while bivalves were the second largest (31.8%) group in terms of total abundance. It was also noticed that the average relative abundance (0.62) and important species index (62.08) of copepods were higher than for other groups that exist in the seagrass meadow, whereas copepod Parvocalanus crassirostris showed both the highest average relative abundance (0.41) and the highest important species index (41.15). The diversity (H') and richness index of the intermediate season were found to be highest due to favourable physico-chemical conditions. Within the referred seasonal cluster, the wet and dry seasons were almost similar in terms of species abundance, while the intermediate season was distinct, with high species diversity backed by ANOSIM analysis results. Copepod and bivalves formed one group with a common similarity level of 0.80. The CCA (Canonical Correspondence Analysis) model established that abiotic factors, especially turbidity, NO2, rainfall, dissolved oxygen and pH were significantly correlated with abundance of individual groups of zooplankton. Zooplankton assemblage and abundance in Lawas were found to be very rich in multiple seasons, indicating that the productivity of uninterrupted seagrass habitat might be high and the system rich in biodiversity.
  4. Fulltext Freshwater fishes (Actinopterygii) of Kenyir Reservoir, Peninsular Malaysia: Updated checklist, taxonomic concerns and alien species
    Aqmal-Naser M, Ali NA, Azmi NU, Fahmi-Ahmad M, Rizal SA, Ahmad AB
    Biodivers Data J, 2023;11:e100337.
    PMID: 38327369 DOI: 10.3897/BDJ.11.e100337
    BACKGROUND: A total of 87 freshwater fish species from 30 families were recorded from the Kenyir Reservoir, Peninsular Malaysia, where 75 are native and 12 are introduced species. Few species still have unstable taxonomy identities which urge further studies. Most of the species were categorised as Least Concern (LC) and two were threatened species; Endangered and Critically Endangered (EN and CR). One introduced species, Gambusiaaffinis is widespread in the human-associated area, while other introduced fish species can be considered low in numbers.

    NEW INFORMATION: Twenty five fish species are recorded for the first time in the Kenyir Reservoir.

  5. Fulltext Understorey bird assemblages in selected environmentally sensitive areas (ESA) of Selangor, Peninsular Malaysia
    Munian K, Mahyudin NAA, Azman SM
    Biodivers Data J, 2023;11:e95670.
    PMID: 38327332 DOI: 10.3897/BDJ.11.e95670
    Environmentally Sensitive Areas (ESA) refer to areas that are of critical importance in terms of ecosystem services such as goods, services and life-support systems, such as water purification, pest control and erosion regulation. In addition, they also refer to areas that harbour the wealth of the nation's biodiversity. However, the classification of ESA in Malaysia is incomprehensible and lacks weightage on biological elements as the current classification is more centred on physical attributes. In order to enhance the existing classification of ESA by introducing biological elements, biological data are urgently required, especially for forest reserves and protected habitat. Hence, we conducted understorey birds surveys in three ESA rank II permanent forest reserves, located in northern Selangor as baseline information to strengthen the ESA classification. The surveys were carried out using mist-netting in three 400 m × 200 m plots. Alpha diversity indices were calculated and showed a significant difference in terms of diversity, composition and biomass of understorey birds between investigated sites. Analysis of similarity (ANOSIM) showed that bird assemblages from forest reserves designated as ESA rank II in Selangor, based on disturbances levels, have weakly diverged and SIMPER analysis has identified six species that contributed to 60% of the differences amongst the bird assemblages. The finding provides the first insight into understorey birds of the study sites and the importance of conserving and preserving ESA of permanent forest reserves, especially the small and fragmented forests.
  6. Fulltext First record of Caligusdussumieri Rangnekar, 1957 (Copepoda, Siphonostomatoida, Caligidae) from Malaysia, with notes on caligids found from Malaysia and on host-specificity of caligids on lutjanid fishes
    Ismail N, Nishida Y, Ohtsuka S, Boxshall G, Bernot JP
    Biodivers Data J, 2024;12:e116598.
    PMID: 38420188 DOI: 10.3897/BDJ.12.e116598
    BACKGROUND: In total, 14 species of Caligus have been reported from Malaysia. Amongst them, four species are reported from lutjanid fishes.

    NEW INFORMATION: Caligusdussumieri Rangnekar, 1957 is reported from Malabar snapper, Lutjanusmalabaricus, purchased from a local wet market in Terengganu, Peninsular Malaysia. This is the first record of this species in Malaysia and it is only the second species assigned to the bonito-group of the genus Caligus to be reported from Malaysia. A key to species of the bonito-group is presented herein. The list of caligids infecting lutjanid fishes and the geographical distributions plus the known hosts of members of the bonito-group of Caligus are discussed.

  7. Fulltext Harmonia manillana (Mulsant), a new addition to Indian Coccinellidae, with changes in synonymy
    Poorani J, Booth RG
    Biodivers Data J, 2016.
    PMID: 27099561 DOI: 10.3897/BDJ.4.e8030
    Harmonia dunlopi (Crotch), a rare lady beetle species, was originally described from 'India' by Crotch (1874). But information on subsequent sightings of this species is absent and it has not been reported by anyone from India and its neighbouring countries ever since its original description. Because of this, Indian records of H. dunlopi were suspected to be probably misidentifications of H. dimidiata (F.), a species common in northern and northeastern India and also widely distributed in the Oriental region.
  8. An updated checklist of the marine fish fauna of Redang Islands, Malaysia
    Du J, Loh KH, Hu W, Zheng X, Affendi YA, Ooi JLS, et al.
    Biodivers Data J, 2019;7:e47537.
    PMID: 31849564 DOI: 10.3897/BDJ.7.e47537
    Background: Redang Islands Marine Park consists of nine islands in the state of Terengganu, Malaysia. Redang Island is one of the largest off the east coast of Peninsular Malaysia, which is famous for its crystal-clear waters and white sandy beaches. The ichthyofauna of the Redang archipelago was surveyed by underwater visual observations between August 2016 and May 2018. Census data were compiled with existing records into the checklist of the marine fish of the Redang archipelago presented herein. A total of 314 species belonging to 51 families were recorded. The most speciose families (Pomacentridae, Labridae, Scaridae, Serranidae, Apogonidae, Carangidae, Gobiidae, Chaetodontidae, Lutjanidae, Nemipteridae and Siganidae) were also amongst the most speciose at the neighbouring Tioman archipelago (except Chaetodontidae). The coral fish diversity index value for the six families of coral reef fishes (Chaetodontidae, Pomacanthidae, Pomacentridae, Labridae, Scaridae and Acanthuridae) of the study sites was 132. We estimated that there were 427 coral reef fish species in the Redang archipelago. According to the IUCN Red List, eight species are Near Threatened (Carcharhinus melanopterus, Chaetodon trifascialis, Choerodon schoenleinii, Epinephelus fuscoguttatus, E. polyphekadion, Plectropomus leopardus, Taeniura lymma and Triaenodon obesus), eleven are Vulnerable (Bolbometopon muricatum, Chaetodon trifasciatus, Chlorurus sordidus, Dascyllus trimaculatus, Epinephelus fuscoguttatus, E. polyphekadion, Halichoeres marginatus, Heniochus acuminatus, Nebrius ferrugineus, Neopomacentrus cyanomos and Plectropomus areolatus) and three are Endangered (Amphiprion clarkia, Cheilinus undulatus and Scarus ghobban) in the Redang archipelago.

    New information: Five species are new records for Malaysia (Ctenogobiops mitodes, Epibulus brevis, Halichoeres erdmanni, H. richmondi and Scarus caudofasciatus) and 25 species are newly recorded in the Redang archipelago.

    Song SL, Yong HS, Chua KO, Eamsobhana P, Lim PE, Chan KG
    Biodivers Data J, 2022;10:e87459.
    PMID: 36761655 DOI: 10.3897/BDJ.10.e87459
    The chrysomelid beetlesPodontiaaffinis and Silanafarinosa are members of the subfamilies Galerucinae and Cassidinae, respectively. This study, based on 16S rRNA gene-targeted metagenomics sequencing, reports the core members and differential abundance of bacterial communities in the larvae and adult beetles of P.affinis and the adult S.farinosa. Cyanobacteria/Melainabacteria group was the predominant phylum in the larvae of P.affinis, while Proteobacteria was the predominant phylum in adult P.affinis and S.farinosa. The number of Order, Family, Genus and Species OTUs in the adult stage of P.affinis was higher than that in the larval stage. The bacterial species richness of adult P.affinis was significantly higher than that of adult S.farinosa. Betaproteobacteria was the predominant class in adult P.affinis, Cyanobacteria in the larvae of P.affinis and Gammaproteobacteria in S.farinosa. The larvae and adult beetles of P.affinis and adult S.farinosahad a low number of unique and shared bacterial OTUs (> 5% relative abundance). The differences in the microbiota indicate possible differences in nutrient assimilation, host taxonomy and other stochastic processes. These findings provide new information to our understanding of the bacteria associated with specialist phytophagous chrysomelid beetles and beetles in general.
  10. Fulltext The first record of a fly of the family Milichiidae (Diptera) interacting with an ant of the genus Polyrhachis Smith, 1857 (Hymenoptera: Formicidae)
    Yusah KM, Fayle TM
    Biodivers Data J, 2014.
    PMID: 25425942 DOI: 10.3897/BDJ.2.e4168
    Flies in the family Milichiidae are often myrmecophilic. We document the first record of a fly from this family interacting with an ant of the genus Polyrhachis. In lowland riparian rainforest in Sabah, Malaysia, we observed a female of the genus Milichia following an ant of the species of P.illaudata, and repeatedly attempting to make close contact. Our observation suggests that the dipteran may have been attempting to feed kleptoparasitically from the Polyrhachis worker, since members of this ant genus often feed on liquid carbohydrate-rich food resources. This is the first time an interaction has been observed between a fly of this family and an ant of this widespread old world tropical genus.
  11. The first record of the parasitic myrmecophilous caterpillar Liphyrabrassolis (Lepidoptera, Lycaenidae) inside Asian weaver ant (Oecophyllasmaragdina) nests in oil palm plantations
    Dwi Advento A, Yusah KM, Salim H, Naim M, Caliman JP, Fayle TM
    Biodivers Data J, 2022;10:e83842.
    PMID: 36761604 DOI: 10.3897/BDJ.10.e83842
    Asian weaver ants (Oecophyllasmaragdina) are an important biocontrol agent in agricultural habitats. We conducted surveys in oil palm plantations in Riau, Indonesia for an obligate myrmecophilous butterfly larvae, Liphyrabrassolis (Lepidoptera, Lycaenidae), that is known to consume weaver ant larvae in other habitat types. We found L.brassolis larvae in five of the twenty nests surveyed, with larval presence not being related to weaver ant nest size. We also observed L.brassolis larvae in a weaver ant mass rearing facility. This is the first report of L.brassolis from oil palm plantations and may have implications for the use of weaver ants as biological control agents.
  12. Fulltext Dispatch from the field: ecology of ground-web-building spiders with description of a new species (Araneae, Symphytognathidae)
    Miller JA, Schilthuizen M, Burmester JL, van der Graaf L, Merckx V, Jocqué M, et al.
    Biodivers Data J, 2014.
    PMID: 24891829 DOI: 10.3897/BDJ.2.e1076
    Crassignathadanaugirangensis sp. n. (Araneae: Symphytognathidae) was discovered during a tropical ecology field course held at the Danau Girang Field Centre in Sabah, Malaysia. A taxonomic description and accompanying ecological study were completed as course activities. To assess the ecology of this species, which belongs to the ground-web-building spider community, three habitat types were surveyed: riparian forest, recently inundated riverine forest, and oil palm plantation. Crassignathadanaugirangensis sp. n. is the most abundant ground-web-building spider species in riparian forest; it is rare or absent from the recently inundated forest and was not found in a nearby oil palm plantation. The availability of this taxonomic description may help facilitate the accumulation of data about this species and the role of inundated riverine forest in shaping invertebrate communities.
  13. Dispatch from the field II: the mystery of the red and blue Opadometa male (Araneae, Tetragnathidae, Opadometa sarawakensis)
    Miller JA, Freund C, Rambonnet L, Koets L, Barth N, van der Linden C, et al.
    Biodivers Data J, 2018.
    PMID: 29674940 DOI: 10.3897/BDJ.6.e24777
    Background: Males of Opadometa are difficult to associate with conspecific females, and sex-matching errors may persist in the taxonomic literature. Recommended best practices for definitive sex matching in this genus suggest finding a male in the web of a female, or better yet, mating pairs.

    New information: A male Opadometa was observed hanging on a frame line of the web of a female Opadometa sarawakensis, a species for which the male was previously undescribed. This occurred during a tropical ecology field course held at the Danau Girang Field Centre in Sabah, Malaysia. A taxonomic description was completed as a course activity.

  14. First record of the fungal genus Neodevriesia Quaedvl. & Crous (Ascomycota, Dothideomycetes, Neodevriesiaceae) isolated from scleractinian corals of Perhentian Islands, Malaysia
    Lee LC, Rizman-Idid M, Alias SA, Palaniveloo K, Gu H
    Biodivers Data J, 2022;10:e81533.
    PMID: 36761577 DOI: 10.3897/BDJ.10.e81533
    Fungal species members of the genus Neodevriesia have been known to occur in marine environments. This report documents the first record of the fungal genus Neodevriesia isolated from scleractinian corals. Three isolated strains were identified from a phylogenetic tree that was constructed, based on the nuclear ribosomal internal transcribed spacer and partial large subunit (ITS + LSU) DNA sequences. Isolates were closely related to both Neodevriesiashakazului (Crous) Crous and Neodevriesiaqueenslandica (Crous, R.G. Shivas & McTaggart) Crous, but formed a distinct clade with strong support that implies a potentially genetic variant of a known species or even a novel species. These findings contribute to the fungal diversity checklist in Malaysia and knowledge about marine fungi associated with scleractinian corals.
  15. Fulltext Bat species diversity trend along an elevation gradient: A study in Crocker Range Park, Sabah, Borneo
    Lok YC, Siau VG, Mohd Kanapiah NAA, Lai TC, Haslan NNHH, Nukili NN, et al.
    Biodivers Data J, 2021;9:e72651.
    PMID: 34803464 DOI: 10.3897/BDJ.9.e72651
    Bats (Order: Chiroptera) is a recognised group of bioindicators due to their sensitivity towards alterations in their immediate surroundings. With the threats of climate change becoming more severe on a daily basis, it is reasonable to collect data on how bat diversity is influenced by elevation. This will be useful to predict and monitor possible upslope shifting of bat species due to increase in surrounding temperature or anthropogenic pressure. Hence, this study aims to uncover the bat diversity trend at different elevations in Crocker Range Park (CRP), Sabah, Malaysia. Bat trappings were conducted in four substations within this park, covering an elevation spectrum from 450 to 1900 m a.s.l. The overall sampling managed to capture 133 individuals of bats, predominantly Pteropodidae, with the addition of two new species locality records for CRP, Murinapeninsularis and Hypsugovondermanni. Simple linear regression analyses revealed that both bat diversity and richness have an inverse linear relationship with elevation. Likewise, the Pearson's correlation value, associating bat diversity with elevation, also shows that they have a negative relationship at r = -0.852. Heterogeneity of habitats explain this trend, as in the lower counterpart of CRP, lowland forests, which are richer in fruit and insect resources persist. Besides, lower land forests have better niche assortment, due to the distinctive layers stratification, allowing bats utilising different guilds to thrive in the same vegetation profile. This study further emphasises the role of CRP to protect most of the bat species found in Borneo, as well as serving as the baseline data for the future studies that look into the impact of temperature increment towards the upslope shifting of the bat population in CRP.
  16. Fulltext Insect community in riparian zones of Sungai Sepetang, Sungai Rembau and Sungai Chukai of Peninsular Malaysia
    Abdullah NA, Radzi SNF, Asri LN, Idris NS, Husin S, Sulaiman A, et al.
    Biodivers Data J, 2019;7:e35679.
    PMID: 31582889 DOI: 10.3897/BDJ.7.e35679
    Riparian areas hold vast number of flora and fauna with exceptional contributions to the ecosystem. A study was conducted in Sungai Sepetang, Sungai Rembau and Sungai Chukai to identify the insect community in a riparian zone of Peninsular Malaysia. Sampling was conducted in six consecutive months from December 2017 to May 2018 during both day and night using sweep nets. Twenty sampling stations (S1-S20) had been assembled along the riverbanks with an average distance of 200 m between each station. The 17,530 collected insects were from 11 orders and consisted of Diptera, Coleoptera, Hemiptera, Hymenoptera, Lepidoptera, Neuroptera, Orthoptera, Blattodea, Thysanoptera, Mantodea and Odonata. The three most abundant orders were Diptera (33.84%; 5933 individuals), Coleoptera (28.82%; 5053 individuals) and Hemiptera (25.62%: 4491 individuals). The collected insect community consisted of different guilds such as the scavenger, predator, herbivore, pollinator and parasitoid. Sungai Sepetang and Sungai Rembau were dominated by mangrove flora, Sonneratia caseolaris (Myrtales: Lythraceae), while Sungai Chukai was dominated by Barringtonia racemosa. There was a significant difference (p < 0.05) in the composition of insects between the three rivers though clustering analysis showed that the insect communities in Sungai Sepetang and Sungai Rembau were 100% similar compared to Sungai Chukai which consisted of a totally different community. There is a significant negative correlation between abundance of insects with salinity and wind speed at Sungai Chukai and Sungai Sepetang.
  17. Fulltext Redescription of the little-known grasshopper Willemsella (Acrididae, Hemiacridinae) from Peninsular Malaysia
    Tan MK, Kamaruddin KN
    Biodivers Data J, 2016.
    PMID: 27099555 DOI: 10.3897/BDJ.4.e7775
    Catantopinae is a huge subfamily and is in need of a major revision. We contribute to the taxonomy of the subfamily by reviewing one poorly known genus, Willemsella Miller, 1934. This is a monotypic genus so far found only in Peninsular Malaysia.
  18. Fulltext The land snail fauna of Batu Kudik, isolated limestone outcrop near Simunjan, Sarawak, Malaysian Borneo (Mollusca, Gastropoda)
    Lee JY, Nasir NS, Marzuki ME, Vermeulen JJ, Khalik MZ
    Biodivers Data J, 2024;12:e115556.
    PMID: 38405381 DOI: 10.3897/BDJ.12.e115556
    BACKGROUND: The present study provides a checklist of land snails collected from Batu Kudik, a small and isolated limestone outcrop in Simunjan, Sarawak. A total of 24 species of land snails, representing 18 genera and 14 families were recorded, including one newly-described subspecies. The most species-rich of the families in Batu Kudik are Diplommatinidae (17%) and Chronidae (17%) with four recorded species from each of the families. Based on our analysis, Plectostomawallaceikudikense subsp. nov., Opisthostomajavanica and Georissapyrrhoderma were identified as the most abundant land snails at this isolated outcrop, whereas Diplommatinaonyx and Everettiaminuta were recorded as the least abundant. All of the land snails at Batu Kudik were exclusively found sheltered between limestone boulders, underscoring the critical role of this outcrop as their refuge for survival. Consequently, conserving this biodiversity-rich limestone area becomes paramount to prevent the local extinction of these land snail species and possibly other organisms that depend on the unique attributes of the limestone for their survival. We also provide detailed descriptions of Plectostomawallaceikudikense, a new subspecies of the genus Plectostoma which is endemic to Batu Kudik.

    NEW INFORMATION: A description of a new subspecies Plectostomawallaceikudikense subsp. nov.

  19. The first record of the thomisid genus Ibana Benjamin, 2014 (Araneae, Thomisidae) from China, with the description of a new species
    Liu K, Li W, Yao Y, Li C, Li S
    Biodivers Data J, 2022;10:e93637.
    PMID: 36761648 DOI: 10.3897/BDJ.10.e93637
    BACKGROUND: The genus Ibana Benjamin, 2014 was established, based on the type species Ibanasenagang Benjamin, 2014 from Borneo, Malaysia. No species of this genus has been recorded from China.

    NEW INFORMATION: A new species of Ibana is described and illustrated, representing the first record of the genus for China. Ibanagan sp. n. differs from its congener by the yellowishbrown longitudinal band on the abdomen and the round, contiguous spermathecae. The distribution of the new species in Jiangxi Province is mapped.

  20. A survey of ctenid spiders (Araneae, Ctenidae) from Xishuangbanna Tropical Botanical Garden, Yunnan, China
    Chu C, Lu Y, Yao Z, Li S
    Biodivers Data J, 2022;10:e87597.
    PMID: 36761608 DOI: 10.3897/BDJ.10.e87597
    BACKGROUND: Amauropelma Raven, Stumkat & Gray, 2001 currently contains 24 species. It is distributed in Australia, India, Indonesia, Laos and Malaysia. This genus has not been found in China. Ctenus Walckenaer, 1805 comprises 213 known species. This genus is distributed worldwide. Currently, only two species, Ctenuslishuqiang Jäger, 2012 and Ctenusyaeyamensis Yoshida, 1998 are known to occur in China.

    NEW INFORMATION: Three new species of ctenid spiders are described from Xishuangbanna Tropical Botanical Garden in Yunnan Province, China: Amauropelmayunnan sp. nov., Ctenusbanna sp. nov. and Ctenusyulin sp. nov. Amauropelma and Ctenusrobustus Thorell, 1897 are reported from China for the first time.
