  1. A new species of Tropidophorus Duméril & Bibron, 1839 (Squamata: Sauria: Scincidae) from Sarawak, East Malaysia (Borneo)
    Pui YM, Karin BR, Bauer AM, Das I
    Zootaxa, 2017 05 03;4258(6):539-550.
    PMID: 28609896 DOI: 10.11646/zootaxa.4258.6.3
    A new species of the genus Tropidophorus is described from Putai, upper Baleh, Kapit districts, Sarawak, East Malaysia (Borneo). Tropidophorus sebi sp. nov. is diagnosable from congeners from Borneo by the combination of the following characters: head shields present, dorsal and lateral scales smooth; parietal scales in two pairs; supraciliaries eight; supraoculars four; supralabials seven; infralabials four; postmental undivided; longitudinal scale rows 58; ventrals 53; transverse scale rows at midbody 34; subcaudals 98; preanals enlarged, single; and subdigital lamellae of Toe IV 19. In addition, we determine the phylogenetic position of this species within the Tropidophorus group based on mitochondrial markers, and present a key to identification of the known Bornean species in the genus.
  2. A new species of black fly with a yellow thorax in the genus Prosimulium (Diptera: Simuliidae) in Japan
    Takaoka H, Saito K, Adler PH, Baba M
    Zootaxa, 2018 Nov 23;4524(4):489-495.
    PMID: 30486108 DOI: 10.11646/zootaxa.4524.4.6
    A new species of black fly, Prosimulium kazukii, is described based on female, male and pupal specimens collected from central Honshu, Japan. It is placed in the Prosimulium magnum species-group, and is characterized in the female and male by yellow thoraces, and in the pupa by the frons and dorsal surface of the thorax without distinct tubercles. By these characters, it is distinguished from all four related species (P. apoina Ono, P. kalibaense Ono, P. sarurense Ono, and P. yezoense Shiraki) of the same species-group in Japan. The female of this new species was previously known as an aberrant form of P. yezoense.
  3. A new species of clearwing moth (Lepidoptera: Sesiidae: Osminiini) from Peninsular Malaysia, exhibiting bee-like morphology and behaviour
    Skowron MA, Munisamy B, Hamid SB, Węgrzyn G
    Zootaxa, 2015;4032(4):426-34.
    PMID: 26624378 DOI: 10.11646/zootaxa.4032.4.7
    A new species of Sesiidae, tribe Osminiini from Peninsular Malaysia, Heterosphecia pahangensis Skowron, displaying numerous bee-mimicking features, is described. DNA barcodes showed significant differences with related taxa. However, the paucity of Sesiidae barcodes from Southeast Asia prevents meaningful taxonomic comparisons. The closest match out of published data on Sesiidae barcodes is Heterosphecia bantanakai, Arita & Gorbunov (2000a) from the tribe Osminiini, which has 9.98% sequence divergence from Heterosphecia pahangensis. Photographs of the moth in its natural habitat are shown. Behavioural aspects, such as mud-puddling and mode of flight, are described and presented in a video.
  4. A new species of genus Ephemeroporus Frey, 1982 (Cladocera: Anomopoda: Chydoridae) from Peninsular Malaysia
    Sinev AY, Yusoff FM
    Zootaxa, 2016 Jun 01;4117(3):399-410.
    PMID: 27395182 DOI: 10.11646/zootaxa.4117.3.7
    Study of Ephemeroporus Frey, 1982 populations from Peninsular Malaysia revealed a new species. Ephemeroporus malaysiaensis sp. nov. is characterized by the presence of four-five large denticles on anal margin of postabdomen instead of two-three, and five distinctive pigmented spots on each valve. Pigmented spots on the valves were never recorded for any species of family Chydoridae. E. malaysiaensis sp. nov. seems to be another endemic Chydoridae species of South-East Asia. E. malaysiaensis sp. nov. is a rare species, associated with emergent macrophytes in the littoral zone of shallow lake. Most of Ephemeroporus populations from Peninsular Malaysia belong to eurybiotic Paleotropical species Ephemeroporus barroisi (Richard, 1984).
  5. A new species of genus Nishada Moore, 1878 (Lepidoptera, Erebidae, Arctiinae) from India
    Joshi R, Kirti JS, Singh N
    Zootaxa, 2016 Oct 28;4179(1):128-132.
    PMID: 27811698 DOI: 10.11646/zootaxa.4179.1.10
    Genus Nishada Moore (1878) was proposed as a monotypic genus, under subfamily Lithosiinae, family Lithosiidae (now Lithosiini), including only Nishada flabrifera Moore (1878) from Calcutta (now as Kolkata), India. The genus is distributed from China to India, Thailand, Malaysia and up to Australia. The Indian fauna of Nishada is reported from North-East Himalayas, West Bengal (Kolkata) and South India. Members of this genus are unmarked, yellow to brown with short and broad wings. Genus Nishada has been taxonomically dealt by many authors but awaits thorough revision.

    HISTORY: Hampson (1900) included a total of ten species: Nishada niveola Hampson, 1900, Nishada syntomioides (Walker, 1862), Nishada impervia (Walker, 1865), Nishada marginalis (Felder 1875), Nishada tula Swinhoe, 1900, Nishada nodicornis (Walker 1862), Nishada rotundipennis (Walker 1862), Nishada flabrifera Moore, 1878, Nishada sambara (Moore 1859) and Nishada xantholoma (Snellen 1879). Swinhoe (1902) and Hampson (1911) then described two new species, Nishada melanistis and Nishada brunneipennis, respectively, followed by Rothschild (1912, 1913) who described a further seven new species, Nishada brunnea, Nishada flavens, Nishada testacea, Nishada griseoflava, Nishada fuscofascia, Nishada louisiadensis and Nishada aurantiaca, bringing the total to 19 species. Strand (1922) catalogued only 13 of these species in Nishada, transferring N. brunnea and N. fuscofascia to genus Scoliacma Meyrick (1886); N. testacea, N.griseoflava and N. louisiadensis Rothschild to Eilema Hübner (1819) and synonymising N. flavens with N. sambara. Next, Matsumura (1927) described N. formosibia, followed by two more species, N. aureocincta Debauche, 1938 and N. benjaminea Roepke, 1946. Holloway (2001) synonymised N. nodicornis with N. rotundipennis and added the description of a new subspecies, Nishada chilomorpha adunca Holloway, 2001 from Borneo, indicating a distributional range as far as North East India. The nominotypical subspecies, N. c. chilomorpha was suggested to be restricted to its type locality of Java. Bucsek (2012) added Nishada cameronensis, Dubatolov & Bucsek (2013) described Nishada schintlmeisteri and Bucsek (2016) described Nishada temenggora. So, at present, Nishada comprises19 species, of which three are known from India (Singh et al. 2014). Herein, we describe one further species, Nishada pseudochilomorpha Joshi & Singh sp. nov., from Jatinga (Assam, India). In addition, new distributional records are reported for N. flabrifera.

  6. A new species of highland vampire crab (Crustacea: Brachyura: Sesarmidae: Geosesarma) from Serian, Sarawak
    Ng PKL, Grinang J
    Zootaxa, 2018 Nov 02;4508(4):569-575.
    PMID: 30485965 DOI: 10.11646/zootaxa.4508.4.5
    A new species of semiterrestrial highland vampire crab of the family Sesarmidae, Geosesarma larsi n. sp., is described from western Sarawak. This brings the number of Bornean Geosesarma species to 12. Geosesarma larsi n. sp. is distinguished from congeners by the structures of the carapace, third maxilliped exopod and gonopods, as well as the proportions of its ambulatory legs. The colour pattern in life is also strikingly different from allied species. Notes on its ecology are provided and conservation threats briefly discussed.
  7. A new species of insular Rock Gecko (Genus Cnemaspis Strauch, 1887) from the Bidong Archipelago, Terengganu, Peninsular Malaysia
    Grismer LL, Jr PL, Ahmad AB, Sumarli AS, Vazquez JJ, Ismail LH, et al.
    Zootaxa, 2014;3755:447-56.
    PMID: 24869832 DOI: 10.11646/zootaxa.3755.5.4
    A new insular species Cnemaspis bidongensis sp. nov. (Squamata: Gekkonidae), is described from Pulau Bidong, Terengganu, Peninsular Malaysia and bears a unique suite of morphological and color pattern characters that differentiate it from all other congeners. Cnemaspis bidongensis sp. nov. is the sister species to C. kendallii (Gray) and represents the fifth insular endemic species of Cnemaspis on archipelagos along the east coast of Peninsular Malaysia. This species survived massive deforestation of the small island of Bidong (260 ha) from the mid 1970s to the early 1990s when the island served as a Vietnamese refugee camp and harbored as many as 40,000 people at one time. We hypothesize that this species' generalized lifestyle contributed to its survival, allowing it to seek refuge in rocky microhabitats.
  8. A new species of karst forest Bent-toed Gecko (genus Cyrtodactylus Gray) not yet threatened by foreign cement companies and a summary of Peninsular Malaysia's endemic karst forest herpetofauna and the need for its conservation
    Grismer LL, Wood PL, Anuar S, Davis HR, Cobos AJ, Murdoch ML
    Zootaxa, 2016 Jan 04;4061(1):1-17.
    PMID: 27395475 DOI: 10.11646/zootaxa.4061.1.1
    A new species of Bent-toed Gecko, Cyrtodactylus gunungsenyumensis sp. nov. of the sworderi complex, is described from Hutan Lipur Gunung Senyum, Pahang, Peninsular Malaysia and is differentiated from all other species in the sworderi complex by having a unique combination of characters including a maximum SVL of 74.7 mm; low, rounded, weakly keeled, body tubercles; 34-40 paravertebral tubercles; weak ventrolateral body fold lacking tubercles; 38-41 ventral scales; an abrupt transition between the posterior and ventral femoral scales; 20-23 subdigital lamellae on the fourth toe; enlarged femoral scales; no femoral or precloacal pores; no precloacal groove; wide caudal bands; and an evenly banded dorsal pattern. Cyrtodactylus gunungsenyumensis sp. nov. is a scansorial, karst forest-adapted specialist endemic to the karst ecosystem surrounding Gunung Senyum and occurs on the vertical walls of the limestone towers as well as the branches, trunks, and leaves of the vegetation in the associated karst forest. Cyrtodactylus gunungsenyumensis sp. nov. is the seventh species of karst forest-adapted Cyrtodactylus and the sixteenth endemic species of karst ecosystem reptile discovered in Peninsular Malaysia in the last seven years from only 12 different karst forests. This is a clear indication that many species remain to be discovered in the approximately 558 isolated karst ecosystems in Peninsular Malaysia not yet surveyed. These data continue to underscore the importance of karst ecosystems as reservoirs of biodiversity and microendemism and that they constitute an important component of Peninsular Malaysia's natural heritage and should be protected from the quarrying interests of foreign industrial companies.
  9. A new species of karst forest-adapted Bent-toed Gecko (genus Cyrtodactylus Gray, 1827) belonging to the C. sworderi complex from a threatened karst forest in Perak, Peninsular Malaysia
    Grismer LL, Belabut DM, Quah ES, Onn CK, Wood PL
    Zootaxa, 2014;3755:434-46.
    PMID: 24869831 DOI: 10.11646/zootaxa.3755.5.3
    A new species of Bent-toed Gecko Cyrtodactylus guakanthanensis sp. nov. of the C. sworderi complex is described from a limestone forest in Perak, Peninsular Malaysia whose karst formations at the type locality are within an active quarry. Cyrtodactylus guakanthanensis sp. nov. can be distinguished from all other Sundaland species by having the following suite of character states: adult SVL 77.7-82.2 mm; moderately sized, conical, weakly keeled, body tubercles; tubercles present on occiput, nape, and limbs, and extend posteriorly beyond base of tail; 37-44 ventral scales; no transversely enlarged, median, subcaudal scales; proximal subdigital lamellae transversely expanded; 19-21 subdigital lamellae on fourth toe; abrupt transition between posterior and ventral femoral scales; enlarged femoral scales; no femoral or precloacal pores; precloacal groove absent; wide, dark postorbital stripes from each eye extending posteriorly to the anterior margin of the shoulder region thence forming a transverse band across the anterior margin of the shoulder region; and body bearing five (rarely four) wide, bold, dark bands. Destruction of the karst microhabitat and surrounding limestone forest will extirpate this new species from the type locality and perhaps drive it to complete extinction given that it appears to be restricted to the particular microhabitat structure of the type locality and is not widely distributed throughout the karst formations. As with plants and invertebrates, limestone forests are proving to be significant areas of high herpetological endemism and should be afforded special conservation status rather than turned into cement.
  10. A new species of karst-adapted Cnemaspis Strauch, 1887 (Squamata: Gekkonidae) from a threatened karst region in Pahang, Peninsular Malaysia
    Grismer LL, Wood PL, Mohamed M, Chan KO, Heinz HM, Sumarli AS, et al.
    Zootaxa, 2013;3746:463-72.
    PMID: 25113489 DOI: 10.11646/zootaxa.3746.3.5
    A new species of karst-adapted gekkonid lizard of the genus Cnemaspis Strauch is described from Gua Gunting and Gua Goyang in a karst region of Merapoh, Pahang, Peninsular Malaysia whose unique limestone formations are in immediate danger of being quarried. The new species differs from all other species of Cnemaspis based on its unique suite of morphological and color pattern characters. Its discovery underscores the unique biodiversity endemic to karst regions and adds to a growing list of karst-adapted reptiles from Peninsular Malaysia. We posit that new karst-adapted species endemic to limestone forests will continue to be discovered and these regions will harbor a significant percentage of Peninsular Malaysia's biodiversity and thusly should be conserved rather than quarried.
  11. A new species of lowland karst dwelling Cnemaspis Strauch 1887 (Squamata: Gekkonidae) from northwestern Peninsular Malaysia
    Wood PL, Quaw SH, Shahrul Anuar MS, Muin MA
    Zootaxa, 2013;3691:538-58.
    PMID: 26167602
    A new species of lowland karst dwelling Cnemaspis Strauch 1887, C. grismeri sp. nov. is described from the southeastern base of the Banjaran Bintang in northern Peninsular Malaysia. It is differentiated from its congeners by a unique combination of characters including size, coloration and scalation. Cnemapis grismeri sp. nov. is most closely related to C. mcguirei, an upland species endemic to the Banjaran Bintang. This phylogeographic pattern is also seen in the upland and lowland Banjaran Bintang species of Cyrtodactylus bintangtinggi and C. bintangrendah, respectively (Grismer et al. 2012). The discovery of yet another endemic gekkonid in the poorly explored karst regions of Peninsular Malaysia underscores the necessity for concentrated collecting efforts in these unique landscapes.
  12. A new species of lowland skink (genus Lipinia Gray, 1845) from northeastern Peninsular Malaysia
    Grismer LL, Ismail LH, Awang MT, Rizal SA, Ahmad AB
    Zootaxa, 2014;3821(4):457-64.
    PMID: 24989758 DOI: 10.11646/zootaxa.3821.4.4
    A new species of scincid lizard, Lipinia sekayuensis sp. nov. from Hutan Lipur Sekayu, Terengganu State in northeastern Peninsular Malaysia is most similar to L. surda (Boulenger) but differentiated from it and all other species of Lipinia by having the combination of an adult SVL of 42.3 mm; six supralabials; five infralabials; four supraoculars; prefrontals widely separated; two loreals; fused frontoparietals; lower eyelids bearing a large, transparent disc; 21 midbody scale rows; 56 paravertertebral scale rows; 65 ventral scale rows; enlarged, precloacal scales; 10 subdigital lamellae on the third finger; 11, 15, and seven lamellae on the third, fourth, and fifth toes, respectively; distal subdigital lamellae keeled; a median row of slightly enlarged, subcaudal scales present; a generally unicolor, dark-brown dorsum bearing nine very faint, diffuse, darker stripes; and an external ear opening replaced by a scaly, auditory depression.
  13. A new species of mole cricket (Orthoptera: Gryllotalpidae: Gryllotalpinae) from Bukit Fraser, Malay Peninsula, with taxa notes on another similar mole cricket
    Tan MK, Kamaruddin KN
    Zootaxa, 2013;3691:324-32.
    PMID: 26167588
    One new species of Gryllotalpa from Bukit Fraser, Pahang of Malay Peninsula is described: Gryllotalpafraser sp. n. Pho tographs of Gryllotalpa hirsuta Burmeister, 1838 were examined and some remarks are made here, including a compari son with Gryllotalpafraser sp. n. and Gyllotalpa nymphicus Tan, 2012.
  14. A new species of moray eel (Anguilliformes: Muraenidae) from Taiwan, with comments on related elongate unpatterned species
    Loh KH, Shao KT, Ho HC, Lim PE, Chen HM
    Zootaxa, 2015;4060:30-40.
    PMID: 26701587 DOI: 10.11646/zootaxa.4060.1.5
    The following nine elongate unpatterned muraenid species of the subfamily Muraeninae, including one new species, are recognized from Taiwan and adjacent waters: Gymnothorax albimarginatus (Temminck & Schlegel), G. dorsalis Seale, G. melanosomatus Loh, Shao & Chen, G. phasmatodes (Smith), G. prolatus Sasaki & Amaoka, G. sagmacephalus Böhlke, Pseudechidna brummeri (Bleeker), Strophidon sathete (Hamilton) and G. pseudomelanosomatus new species, described from two specimens. This new moray eel is distinguished from its similar species, G. melanosomatus, by the following features: grey brown body (vs. black), snout length 20.5% (vs. 17.8%) of head length, smaller eye diameter 8.2% (vs. 10.0%) of head length; preanal length 49.5% (vs. 58.5%) total length, and preanal vertebrae 89-89 (vs. 105-109). Phylogenetic relationships of the nine species were examined using nucleotide sequence data from partial sequences of mitochondrial ND5 gene (600 bp), and seven species form COI (600 bp). The genetic analyses suggest that G. pseudomelanosomatus is distinct from G. melanosomatus and the other six species of Gymnothorax. Morphological features and mitogenetic affinities strongly suggest that "G." dorsalis should be placed in Strophidon rather than in Gymnothorax. The results also suggest that employment of ND5 and COI gene sequences are rather useful for identification of species and for obtaining reasonable insights into the phylogeny of the muraenid species.
  15. A new species of spine-headed katydid Mesagraecia Ingrisch, 1998 (Conocephalinae: Agraeciini), with key to species
    Tan MK, Ingrisch S, Kamaruddin KN
    Zootaxa, 2015 Dec 11;4057(3):437-43.
    PMID: 26701492 DOI: 10.11646/zootaxa.4057.3.9
    The taxonomy of poorly known Mesagraecia Ingrisch, 1998 is reviewed. A new species of Mesagraecia spine-headed katydid (Conocephalinae: Agraeciini) is described from Bukit Larut, Perak, Peninsular Malaysia: Mesagraecia larutensis sp. n. A key to species is also presented.
  16. A new species of the genus Larutia (Squamata: Scincidae) from Gunung Penrissen, Sarawak, Borneo
    Fukuyama I, Hikida T, Hossman MY, Nishikawa K
    Zootaxa, 2019 Aug 29;4661(3):zootaxa.4661.3.6.
    PMID: 31716700 DOI: 10.11646/zootaxa.4661.3.6
    We collected a specimen of a scincid lizard of Larutia Böhme, 1981 from the edge of a primary forest on Gunung Penrissen, Kuching Division, Sarawak, Malaysian Borneo. The single specimen of the new species differs from all other known congeners by the molecular divergence in the mitochondrial ND1 gene and morphological characters including small adult body size (SVL 84 mm); 22 longitudinal scale rows around midbody; first pair of chinshields contacting second infralabial; second pair of chinshields separated from infralabials by an elongated scale; two subdigital lamellae on second toe; and body without yellow or pale bands or spots. It is the ninth species described in the genus and the second species of Larutia in Borneo.
  17. A new species of the genus Pseudohomonyx Arrow, 1908 (Coleoptera: Scarabaeidae: Dynastinae) from Malaysia and Thailand, with first description of P. apoensis Miyake & Yamaya, 1997 male and a catalogue of the genus
    Geshev QYG, Pathomwattananurak W
    Zootaxa, 2023 Oct 31;5361(1):114-124.
    PMID: 38220773 DOI: 10.11646/zootaxa.5361.1.6
    Pseudohomonyx continentalis Yang & Pathomwattananurak, new species from Malaysia and Thailand, is described and illustrated herein. Male of P. apoensis Miyake & Yamaya, 1997 is described and illustrated for the first time. Pseudohomonyx javanus (Burmeister, 1847) is newly recorded from Malaysia and Thailand. An annotated catalogue and a distribution map for the genus are also provided.
  18. A new species of the genus Raphidopus Stimpson, 1858 (Crustacea: Decapoda: Anomura: Porcellanidae) from Peninsular Malaysia, with additional records of R. johnsoni Ng Nakasone, 1994 from Southeast Asia, and a key to species in the genus
    Osawa M, Ng PKL
    Zootaxa, 2018 Jun 11;4433(1):111-126.
    PMID: 30313241 DOI: 10.11646/zootaxa.4433.1.6
    A new species of the porcellanid genus Raphidopus Stimpson, 1858, is described on the basis of specimens from Penang and Kuala Selangor, Peninsular Malaysia. Raphidopus brevipes n. sp. is distinguished from its allied congeners, R. indicus Henderson, 1893 and R. johnsoni Ng Nakasone, 1994, by the proportionally narrower carapace and stouter ambulatory legs, as well as the different dentition on the cutting edge of the dactylus of the larger cheliped. Raphidopus johnsoni, previously known only by the holotype from Singapore, is now also recorded from Phuket (Thailand) and Java (Indonesia). Raphidopus indicus and R. johnsoni are rediagnosed on the basis of the respective type material and other specimens. A key to species of the genus Raphidopus is provided.
  19. A new species of the genus Trichoformosomyia Townsend from Malaysia (Diptera: Tachinidae)
    Tachi T
    Zootaxa, 2013;3702:61-70.
    PMID: 26146706
    A new species of Trichoformosomyia, T. abbreviata sp. nov., is described from Sabah, Malaysia. Trichoformosomyia sauteri Baranov is redescribed and it is newly recorded from China, Vietnam and Japan. A key to the three known species of Trichoformosomyia is given and monophyly of the genus is briefly discussed based on adult morphology.
  20. A new species of the rare monotypic genus Cyrtinoclerus Chapin from Borneo, with notes on Meprinogenus Kolibáč (Coleoptera: Thanerocleridae)
    Kolibáč J
    Zootaxa, 2023 Apr 27;5271(3):569-578.
    PMID: 37518109 DOI: 10.11646/zootaxa.5271.3.9
    Cyrtinoclerus sabahensis sp. nov. of the less diverse cleroid family Thanerocleridae is described from Borneo. The unique specimen was found in the Malaysian state of Sabah and represents the first collecting record of the genus in one hundred years. The new species is assigned to the hitherto monotypic genus Cyrtinoclerus Chapin, 1924, whose single species is known from a single specimen from Basilan, Philippines, with no subsequently collected specimens known to date. Cyrtinoclerus is distinct in its unique synapomorphies, namely the tarsi with formula 5-5-5 but tarsomeres 4 reduced in size, elytron depressed in basal third with distinct bulge, and seriate punctation of elytra. The genus is re-examined and again classified within Thanerocleridae. A systematic status of Cyrtinoclerus and its relative Meprinogenus Kolibáč, 1992, also known only from two just one-hundred-year-old specimens, is discussed and possible synonymy of the latter genus suggested. The family Thanerocleridae now comprises 38 extant species in eleven genera and four extinct Cretaceous genera and species found in Burmese and Charentese ambers. A phylogenetic analysis of all fifteen extinct and extant genera of Thanerocleridae based on 36 morphological characters is presented and updated key to the tribe Thaneroclerini provided.
