PMID: 36760727 DOI: 10.3897/phytokeys.211.83985

Two new species of Boesenbergia, B.sugudensis sp. nov. and B.truncata sp. nov. were discovered in Sabah, Malaysian Borneo. Boesenbergiasugudensis resembles B.imbakensis in that the leaf sheath of the plant is not thickened and in the anther thecae dehiscing by longitudinal slits, but differs in having a longer petiole and tubular calyx. Boesenbergiatruncata resembles B.orbiculata by the short petiole and a bilobed calyx, but differs by the truncate leaf base, the acute leaf apex, opposite leaves with a narrower lamina parallel to the ground and anther thecae dehiscing by pores. The new species are described and illustrated in detail.

Siti-Munirah MY, Suhaida M, Eddie C

PhytoKeys, 2022;211:1-11.
PMID: 36760731 DOI: 10.3897/phytokeys.211.89453

Thismialimkokthayi, a distinct mitriform species of the mycoheterotrophic genus Thismia, is described and illustrated. It was found at a locality in the upland areas of Genting Highlands, Pahang, Malaysia. This new species is morphologically similar to members of Thismiasect.Geomitra, but differs in several characteristics, including the colour of the floral tube, the inner surface of the floral tube with longitudinal ribs and absent transverse bars, a stamen apex with a central lobe (prolongation of the rib) and two lateral lobes (the tips of each are recurved) and a black-purplish stigma. Thismialimkokthayi is provisionally classified as Critically Endangered according to the IUCN Red List Categories and Criteria.
Description of three new species previously identified as Stolephorusbengalensis (Dutt & Babu Rao, 1959) or Stolephorusinsularis Hardenberg, 1933 and a re-description of S.bengalensis (Chordata, Osteichthyes, Clupeiformes, Engraulidae)

PMID: 36760758 DOI: 10.3897/zookeys.1121.84171

Examination of numerous specimens characterised by predorsal scute, long maxilla, indented preopercle and pelvic scute lacking a spine and previously identified as Stolephorusbengalensis (Dutt & Babu Rao, 1959) or Stolephorusinsularis Hardenberg, 1933, revealed four distinct species, true S.bengalensis (distributed from the Bay of Bengal to Pakistan) and three new species, viz., Stolephoruseldorado sp. nov. (Taiwan to Java, Indonesia), Stolephorusdiabolus sp. nov. (Strait of Malacca, from Penang , Malaysia, to Singapore) and Stolephoruseclipsis sp. nov. (Bintan Island, Riau Archipelago, Indonesia). Characters separating the four species include numbers of gill rakers on each gill arch and vertebrae and pelvic fin and dorsal-fin ray lengths. Two molecular markers (mitochondrial cytochrome b and cytochrome oxidase I genes) demonstrated the distinction of three of the species examined morphologically and enabled a reconstruction of their phylogenetic relationships. Each species was genetically divergent from the others by 3.5%-7.7% mean uncorrected distance in the mitochondrial cytochrome oxidase I gene.

PMID: 36760859 DOI: 10.3897/zookeys.1126.90916

A new genus of the tribe Alysiini (Hymenoptera, Braconidae, Alysiinae) is described with specimens from India, Indonesia, Malaysia, Singapore, Thailand, and Vietnam, and six new species are described: Anamalysiaidiastimorpha sp. nov. (type species), A.knekosoma sp. nov., A.mellipes sp. nov., A.transversator sp. nov., A.vandervechti sp. nov., and A.vanhengstumi sp. nov.. We transfer one species from Coelalysia to Anamalysia: A.urbana (Papp, 1967) comb. nov. from Singapore and one species from Alysiasta to Anamalysia: A.triangulum (Fischer, 2006) comb. nov. from Malaysia, Laos, Indonesia and Vietnam. A key to the genus of Anamalysia is included.
Cladosporium spp. endogenous endophthalmitis simulating the classic "headlight-in-the-fog" appearance of active toxoplasmosis

Abd Hamid A, Suan ALL, Hashim H, Kamarudin Z, Muhammed J

Oman J Ophthalmol, 2022;15(3):379-381.
PMID: 36760965 DOI: 10.4103/ojo.ojo_459_20

Endogenous fungal endophthalmitis caused by an unusual fungus poses both diagnostic and therapeutic challenges. We report a case of endogenous endophthalmitis caused by a rare mold, namely Cladosporium spp., which presented with a foveal abscess. A 52-year-old male patient who was diagnosed with rectal carcinoma presented with pain, redness, and a loss of vision in the right eye. He had been experiencing the symptoms for 1 week. The patient had undergone gastrointestinal surgery 2 weeks before experiencing the eye complaint. His best-corrected visual acuity was hand movements. Fundus examination revealed a foveal abscess of around a half-disc diameter in size that simulated retinochoroiditis with vitritis. Optical coherence tomography of the macula revealed a hyperreflective lesion in the fovea, which breached the full thickness of the fovea and extended into the preretinal space. Ocular toxoplasmosis was considered. On that basis, oral trimethoprim/sulfamethoxazole was given for 1 week, although the patient's condition worsened. A vitreous tap and an intravitreal combination of vancomycin, ceftazidime, and amphotericin B were administered twice but did not improve the patient's condition. Pars plana vitrectomy was performed and the vitreous biopsy results revealed the presence of Cladosporium spp. Intravitreal voriconazole was given three times and the foveal abscess resolved into a scar. Endophthalmitis caused by Cladosporium spp. is uncommon and published case reports are extremely limited. The present case may provide insight into the variable presentation of fungal endophthalmitis and, therefore, assist with the early diagnosis and appropriate management of the condition.

PMID: 36761068 DOI: 10.33393/dti.2022.2522

INTRODUCTION:: Detection and diagnosis of methicillin-resistant Staphylococcus aureus (MRSA) are important in ensuring a correct and effective treatment, further reducing its spread. A wide range of molecular approaches has been used for the diagnosis of antimicrobial resistance (AMR) in MRSA. This review aims to study and appraise widely used molecular diagnostic methods for detecting MRSA.
METHODS:: This meta-narrative review was performed by searching PubMed using the following search terms: (molecular diagnosis) AND (antimicrobial resistance) AND (methicillin-resistant Staphylococcus aureus). Studies using molecular diagnostic techniques for the detection of MRSA were included, while non-English language, duplicates and non-article studies were excluded. After reviewing the libraries and a further manual search, 20 studies were included in this article. RAMESES publication standard for narrative reviews was used for this synthesis.
RESULTS:: A total of 20 full papers were reviewed and appraised in this synthesis, consisting of PCR technique (n = 7), deoxyribonucleic acid (DNA) Microarray (n = 1), DNA sequencing (n = 2), Xpert MRSA/SA BC assay (n = 2), matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) (n = 2), MLST (n = 4), SCCmec typing (n = 1) and GENECUBE (n = 1).
DISCUSSION:: Different diagnostic methods used to diagnose MRSA have been studied in this review. This study concludes that PCR has been extensively used due to its higher sensitivity and cost-effectiveness in the past five years

Zookeys, 2022;1102:177-190.
PMID: 36761156 DOI: 10.3897/zookeys.1102.82228

We present a comprehensive checklist of scleractinian (hard) corals for the Mersing Islands, Malaysia based on surveys conducted at 24 reefs across protected and unprotected marine areas. A total of 261 species of corals from 16 families and one incertae sedis (Pachyseris spp.) were recorded, along with ten records that are new for the east coast of Peninsular Malaysia. Compared against the IUCN Red List, 46.7% of coral species found in the Mersing Islands were of Least Concern (LC), 29.5% as Near Threatened (NT) and 16.4% Vulnerable (V). Only one recorded species, Pectiniamaxima (Moll & Best, 1984), was listed as Endangered (EN). Baseline species diversity data are essential for the monitoring and management of marine biodiversity, especially within marine protected areas. With both protected and unprotected coral reef areas in the vicinity of the widely scattered Mersing Islands, the diversity and distribution of coral species can be used as the basis for area-based conservation and management strategies. The diversity and abundance of scleractinian corals of each island or area should be surveyed periodically to ensure the appropriate level of protection is afforded to retain scleractinian biodiversity in this region.

Flying fox (Pteropushypomelanus) belongs to the frugivorous bats, which play a crucial role in maintaining proper functioning of an ecosystem and conservation of the environment. Bats are well-known carriers of pathogenic viruses, such as BatCov RaTG13 from the coronavirus family that share 90.55% with SARS-CoV-2, the pathogen causing recent global pandemic coronavirus disease 19 (COVID-19). However, bats' possible role as a carrier of pathogenic bacteria is less explored. Here, using metabarcoding analysis through high-throughput sequencing, we explored the gut microbiome composition of different island populations on the east and west coasts of Peninsula Malaysia. The 16S rRNA gene in samples from Redang Island, Langkawi Island, Pangkor Island and Tinggi Island was amplified. Bacterial community composition and structure were analysed with α and β diversity metrics. A total of 25,658 operational taxonomic units at 97% similarity were assigned to eight phyla, 44 families, 61 genera and 94 species of microbes. The Proteobacteria was the dominant phylum in all populations. Meanwhile, the genera Enterobacter, Pseudomonas and Klebsiella, isolated in this study, were previously found in the rectum of other fruit bats. Our analyses suggest that Redang Island and Langkawi Island have high bacteria diversity. Thus, we found geographic locality is a strong predictor of microbial community composition and observed a positive correlation between ecological features and bacterial richness.
Two new species and a new record of the Encarsialongifasciata-group (Hymenoptera, Aphelinidae) from Malaysia and China

Geng H, Li CD, Polaszek A, Liu SZ

Biodivers Data J, 2022;10:e91069.
PMID: 36761528 DOI: 10.3897/BDJ.10.e91069

BACKGROUND: The genus Encarsia Förster, 1878, which is the largest genus of the family Aphelinidae, contains 453 valid species worldwide. Most species of Encarsia with known biology are primary endoparasitoids of Aleyrodidae and Diaspididae.
NEW INFORMATION: Species of the Encarsialongifasciata-group from Malaysia and China are reviewed. This is the first record of this group from Malaysia. Two new species, E.borneensis Geng & Li sp. n. and E.pauroseta Geng & Li sp. n., are described and illustrated. Encarsialongifasciata is newly recorded from Malaysia (Borneo). An updated key to the longifasciata-group species (females) worldwide is provided.

The long-tailed macaque (Macacafascicularis) has a wide range in both Peninsular Malaysia and Borneo. Although the primates are especially vulnerable to habitat alterations, this primate lives in disturbed habitats due to human-induced land-use. Thus, this study presents a faecal metabarcoding approach to clarify the plant diet of long-tailed macaques from five locations in Peninsular Malaysia to represent fragmented forest, forest edge, island and recreational park habitats. We extracted genomic DNA from 53 long-tailed macaque faecal samples. We found 47 orders, 126 families, 609 genera and 818 species across these five localities. A total of 113 plant families were consumed by long-tailed macaques in Universiti Kebangsaan Malaysia, 61 in the Malaysia Genome and Vaccine Institute, 33 in Langkawi Island, 53 in Redang Island and 44 in the Cenderawasih Cave. Moraceae (33.24%) and Fabaceae (13.63%) were the most common families consumed by long-tailed macaques from the study localities. We found that habitat type impacted diet composition, indicating the flexibility of foraging activities. This research findings provide an understanding of plant dietary diversity and the adaptability of this macaque with the current alteration level that applies to long-tailed macaque conservation management interest in the future.

Biodivers Data J, 2022;10:e85676.
PMID: 36761545 DOI: 10.3897/BDJ.10.e85676

BACKGROUND: The effects of small-scale disturbances, such as monsoon, are understudied in tropical regions. The storms associated with monsoon events not only modify the local macroalgal community structure, but also reveal the continuation of short-term recolonisation. Thus, this study aims to determine the variation in species, assemblage and cover of macroalgae during the monsoonal cycle from 2015 to 2016. This paper presents data on the spatial and temporal distribution of benthic macroalgae along the coastline of Johor, Malaysia. The information is presented as raw and partially-processed data, which summarises the cover and frequency of macroalgae at the respective study sites. This paper describes an important set of data that can be used further for in-situ experiments on the effects of environmental disturbances towards pioneer and climax species in tropical areas.
NEW INFORMATION: This study provides a description of the east coast shore of Peninsular Malaysia, specifically in Johor coast in 2015-2016. The spatial and temporal distribution and abundance of a total of 41 taxa were assessed at four monsoon-exposed locations. These data provide a comprehensive baseline against disturbance and recolonisation of macroalgal community can be effectively and objectively evaluated.

Malaysia is a tropical country that has consistently been facing a prevalent threat of mosquito-borne diseases. Amongst the plethora of diseases, the most common mosquito-borne disease in the country is dengue fever, transmitted by Aedes spp. mosquitoes. This study aims to examine the effects of human activity associated with different land use on mosquito population composition and diversity. Our study site is Chini Lake, a naturally occurring lake and the second-largest freshwater body in Malaysia. The areas surrounding the Lake have been subjected to various human activities, such as economic development and conversion into rubber plantations, while some areas remain pristine, making Chini Lake an ideal location to examine the gradient of human disturbances on mosquito composition and diversity. We sampled adult mosquitoes and larvae across a range of sites with different levels of human disturbance. As expected, in areas with high disturbance scores, the species richness of adult and larval mosquitoes were reduced while the abundance was higher. The results also revealed minimal overlap between species captured for adult and larval samplings, suggesting that land-use changes affect both life stages differently. Different resource requirements of adult and larval mosquitoes likely led to the observed diversity pattern in this small survey. We suggest future work to look into how habitat heterogeneity affects both life stages and sexes of mosquito diversity patterns and distribution.
First record of the fungal genus Neodevriesia Quaedvl. & Crous (Ascomycota, Dothideomycetes, Neodevriesiaceae) isolated from scleractinian corals of Perhentian Islands, Malaysia

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.
Exploring the predation of large land snails using preyed shell remains from rock anvil sites in a tropical limestone rainforest in Malaysia

Woo SY, Foon JK, Liew TS

Biodivers Data J, 2022;10:e90063.
PMID: 36761581 DOI: 10.3897/BDJ.10.e90063

The study of prey-predator interactions between land snails and birds offers important insights into evolutionary and ecological relationships. Here, we report a case study of rock anvils presumably used by the birds Myophonuscaeruleus and Enicurusruficapillus in a cave cavity of a limestone hill in Malaysia. We did not detect any other species in the plots and, therefore, based on our short study duration, we cannot rule out the possibility that other species, such as mammals, preyed on the snails. The predated shell remains of four land snails namely, Hemiplecta sp., Cyclophorusperdixperdix, Amphidromusatricallosusperakensis and Cyclophorussemisulcatus, were found around rock anvils in the nine plots. Finally, we discussed the potential and the limitations of using shell remains of preyed land snails for behavioural, ecological and evolutionary studies between land snails and their predators.
Fulltext Determining the diet of wild Asian elephants (Elephasmaximus) at human-elephant conflict areas in Peninsular Malaysia using DNA metabarcoding

PMID: 36761586 DOI: 10.3897/BDJ.10.e89752

Human-elephant conflict (HEC) contributes to the increasing death of Asian elephants due to road accidents, retaliatory killings and fatal infections from being trapped in snares. Understanding the diet of elephants throughout Peninsular Malaysia remains crucial to improve their habitat quality and reduce scenarios of HEC. DNA metabarcoding allows investigating the diet of animals without direct observation, especially in risky conflict areas. The aim of this study was to determine: i) the diet of wild Asian elephants from HEC areas in Peninsular Malaysia using DNA metabarcoding and ii) the influence of distinct environmental parameters at HEC locations on their feeding patterns. DNA was extracted from 39 faecal samples and pooled into 12 groups representing the different sample locations: Kuala Koh, Kenyir, Ulu Muda, Sira Batu, Kupang-Grik, Bumbun Tahan, Belum-Temengor, Grik, Kampung Pagi, Kampung Kuala Balah, Aring 10 and the National Elephant Conservation Centre, which served as a positive control for this study. DNA amplification and sequencing targeted the ribulose-bisphosphate carboxylase gene using the next-generation sequencing Illumina iSeq100 platform. Overall, we identified 35 orders, 88 families, 196 genera and 237 species of plants in the diet of the Asian elephants at HEC hotspots. Ficus (Moraceae), Curcuma (Zingiberaceae), Phoenix (Arecaceae), Maackia (Fabaceae), Garcinia (Clusiaceae) and Dichapetalum (Dichapetalaceae) were the highly abundant dietary plants. The plants successfully identified in this study could be used by the Department of Wildlife and National Parks (PERHILITAN) to create buffer zones by planting the recommended dietary plants around HEC locations and trails of elephants within Central Forest Spine (CFS) landscape.

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.
