  1. Solving the taxonomic identity of Hipposideros cineraceus sensu lato (Chiroptera: Hipposideridae) in the Thai-Malay Peninsula, with the description of a new species
    Wongwaiyut P, Karapan S, Saekong P, Francis CM, Guillén-Servent A, Senawi J, et al.
    Zootaxa, 2023 May 03;5277(3):401-442.
    PMID: 37518310 DOI: 10.11646/zootaxa.5277.3.1
    A new species of small Hipposideros in the bicolor group is described based on specimens from Thailand and Malaysia. It can be distinguished from other small Hipposideros in Southeast Asia by a combination of external, craniodental, and bacular morphology, as well as echolocation call frequency. The new species has a distinct rounded swelling on the internarial septum of the noseleaf, with a forearm length of 35.3-42.6 mm, greatest skull length of 15.94-17.90 mm, and a call frequency of maximum energy of 132.3-144.0 kHz. Although clearly different in morphology, the new species forms a sister clade with H. kunzi and H. bicolor in the phylogenetic trees based on mitochondrial DNA. In addition, this study reports echolocation and genetic data, with a confirmed record of H. einnaythu from Thailand for the first time. The new species most closely resembles H. einnaythu. However, it differs in the details of the noseleaf and craniodental morphology, and it has a genetic distance of 9.6% and 10.4% based on mitochondrial COI and ND2, respectively. It is currently documented from five localities: two in peninsular Thailand, at Hala Forest in Yala Province, and Phru To Daeng Swamp Forest in Narathiwat Province, one from peninsular Malaysia at Krau Wildlife Reserve in Pahang, and another two in Sabah, Malaysian Borneo at Gunung Kinabalu, and near Madai Caves. However, it is likely that many previous records of "H. cineraceus" from Borneo refer to this species. Most records of the species are from lowland evergreen rainforest, though one record from Sabah was at 1800m. The roosting sites for this new species are currently unknown. Future research with a combination of data such as genetics, echolocation and morphology would be necessary to further determine the species geographic distribution in Southeast Asia.
  2. Simulium ledangense, a new species of the Simulium feuerborni species-group of the subgenus Nevermannia (Diptera: Simuliidae) from Mount Ledang, Peninsular Malaysia
    Ya'cob Z, Takaoka H, Sofian-Azirun M
    Zootaxa, 2014;3881(3):228-36.
    PMID: 25543632 DOI: 10.11646/zootaxa.3881.3.2
    Simulium (Nevermannia) ledangense sp. nov. is described from females, males, pupae and mature larvae from Peninsular Malaysia. This new species is assigned to the Simulium feuerborni species-group of the subgenus Nevermannia, and is characterized by the pupa having a very long stalk of the ventral paired gill filaments, which is almost five times longer than the interspiracular trunk and female tergites of segments 2 and 5 to 7 shiny. Taxonomic notes are given to distinguish this new species from three known species of the S. feuerborni species-group from Malaysia.
  3. Simulium hiroyukii, a new species of the subgenus Gomphostilbia (Diptera: Simuliidae) from Mount Murud, Sarawak, Malaysia
    Ya'cob Z, Takaoka H, Sofian-Azirun M
    Zootaxa, 2015;3911(3):424-32.
    PMID: 25661622 DOI: 10.11646/zootaxa.3911.3.8
    Simulium (Gomphostilbia) hiroyukii is described based on females, males, pupae and larvae collected in Mount Murud, Sarawak, Malaysia. This new species is assigned to the Simulium darjeelingense species-group of the subgenus Gomphostilbia, and is characterized by the darkened fore coxae and the pupal gill with eight long filaments, of which middle and dorsal triplets have elongated primary and secondary stalks, respectively.

    Takaoka H, Ya'cob Z, Sofian-Azirun M
    Zootaxa, 2018 Oct 12;4498(1):1-65.
    PMID: 30486086 DOI: 10.11646/zootaxa.4498.1.1
    The classification, annotated list and keys for the black fly species from Peninsular Malaysia are updated. The number of black fly species increased from 38 in 1995 to 62 (including a new species herein described) in 2018. The 62 species are classified in four subgenera of the genus Simulium: one species in Daviesellum, 35 species in Gomphostilbia, five species in Nevermannia and 21 species in Simulium. Species in the latter three subgenera are further placed in species-groups or subgroups. Keys are provided for females, males, pupae and mature larvae. Simulium (S.) perakense sp. nov. is described and placed in the S. striatum species-group. The males of S. (G.) decuplum, S. (G.) tahanense, S. (S.) malayense, the female of S. (G.) adleri, and the female and larva of S. (G.) varicorne are described for the first time. The female, male, pupa and larva of S. (G.) trangense, the male and pupa of S. (G.) varicorne and the pupa of S. (G.) adleri are redescribed. Simulium (G.) sp. A is identified as S. (G.) pegalanense. Brief notes for each species are given on morphological characteristics, aquatic habitats and geographical distributions.
  5. Two new species of Cyrtodactylus (Squamata: Gekkonidae) from the Southern Bukit Barisan Range of Sumatra and an estimation of their phylogeny
    Harvey MB, O'connell KA, Barraza G, Riyanto A, Kurniawan N, Smith EN
    Zootaxa, 2015;4020(3):495-516.
    PMID: 26624112 DOI: 10.11646/zootaxa.4020.3.5
    We describe Cyrtodactylus psarops sp. nov. and C. semicinctus sp. nov., two new species of bent-toed geckos from montane forests in the southern Bukit Barisan Range of Sumatra, Indonesia. The new species are closely related to one another and to C. semenanjungensis, a lowland species currently known only from Peninsular Malaysia. Three characters of the new species immediately distinguish them from most congeners in the Sunda Region: they lack transversely enlarged subcaudals, have a precloacal depression, and have a greatly enlarged scale positioned at the apex of a continuous series of femoral and precloacal pore-bearing scales. They differ from one another in cephalic pattern, tuberculation of the brachium, and in numbers of cloacal tubercles, dorsal bands, and ventrals in a transverse row. The greatly enlarged scale at the apex of the precloacal pores appears to be a rare apomorphy of these two species and C. agamensis.
  6. Rediscovery of Micryletta inornata (Boulenger, 1890) from Sumatra: redescription, molecular identity, and taxonomic implications
    Alhadi F, Hamidy A, Farajallah A, Munir M, Atmaja VY, Garg S, et al.
    Zootaxa, 2019 Jun 04;4613(1):zootaxa.4613.1.5.
    PMID: 31716427 DOI: 10.11646/zootaxa.4613.1.5
    Micryletta inornata (Boulenger 1890), the type species of the genus Micryletta, was originally described from the island of Sumatra in Indonesia. Subsequently, this species has been widely reported from Sundaland (Sumatra and Malay Peninsula), Indo-China, Northeast India and South Andaman, up to southern China and Taiwan. However, since the original description there has been no further report of this species from the type locality or the island. During a herpetofaunal survey in Sumatra, several specimens that are morphologically concordant with the original description and the syntypes of M. inornata were found, and thus the species was rediscovered after 125 years. Here, we provide a redescription of the species based on the freshly collected specimens, along with a detailed morphological and molecular comparison with known congeners. Further, using molecular data from the mitochondrial 16S rRNA gene, our study recovered the Sumatran M. inornata as a phylogenetically distinct lineage from all other populations previously referred to this species. This confirms that all known Micryletta 'inornata' populations from regions outside Sumatra constitute several other lineages representing either new species or previously available names currently considered as synonyms, consequently requiring taxonomic validation in the future.
  7. Horned and spiky: Tegotettix derijei sp. n. (Orthoptera: Tetrigidae) is a peculiar new pygmy grasshopper species from Mindanao
    Patano RRJ, Mohagan AB, Tumbrinck J, Amoroso VB, Skejo J
    Zootaxa, 2021 Feb 19;4933(2):zootaxa.4933.2.2.
    PMID: 33756795 DOI: 10.11646/zootaxa.4933.2.2
    A new peculiar, spiky, and yellowish species of the genus Tegotettix Hancock, 1913 is described from the Davao region of the island of Mindanao (the Philippines)-T. derijei sp. n. (Mindanao horned pygmy devil). The species is visually similar to T. cristiferus (Günther, 1935) from Borneo and T. armatus Hancock, 1913 from Borneo, which is the type species of the genus, and of which a new record from Sabah is also presented in the study. The new species is also similar to an undescribed species from Bukidnon, which we presented by photographs in its natural habitat. To date, T. armatus was known only from old descriptions and drawings and has not been reported for more than 100 years. A brief overview of the species of the genus Tegotettix, with its division into three species groups, is presented.
  8. An annotated catalogue of the pygmy grasshoppers of the tribe Scelimenini Bolívar, 1887 (Orthoptera: Tetrigidae) with two new Scelimena species from the Malay Peninsula and Sumatra
    Muhammad AA, Tan MK, Abdullah NA, Azirun MS, Bhaskar D, Skejo J
    Zootaxa, 2018 Sep 25;4485(1):1-70.
    PMID: 30313773 DOI: 10.11646/zootaxa.4485.1.1
    Pygmy grasshoppers (Tetrigidae) are a speciose group of complicated taxonomy, with many species requiring clarification on their species boundaries, and more still awaiting discovery. Two new species of Scelimena Serville, 1838 are described: (1) from S. discalis species group S. gombakensis sp. nov. and (2) from S. hexodon species group Scelimena marta sp. nov. Catalogue of Scelimenini genera (15) and species (100) is presented and taxonomy and biogeography of the tribe are discussed. New and resurrected combinations are: Falconius becvari (Buzzetti Devriese, 2008) comb. nov. (of Gavialidium becvari), Gavialidium carli Hebard, 1930 comb. resurr. (of Bidentatettix carli), Indoscelimena india (Hancock, 1907) comb. nov. (of Scelimena india), Paragavialidium nodiferum (Walker, 1871) comb. nov. (of Platygavialidium nodiferum), Platygavialidium productum (Walker, 1871) comb. nov. (of Gavialidium productum), Scelimena hexodon (Haan, 1843) comb. resurr. (of Hexocera hexodon), Scelimena rosacea (Hancock, 1915) comb. resurr. (of Amphibotettix rosaceus), Tegotettix bufocrocodil (Storozhenko Dawwrueng, 2015) comb. nov. (of Gavialidium bufocrocodil). New synonyms are: Gavialidium phangensum Mahmood, Idris Salmah, 2007 syn. nov. (of Eufalconius pendleburyi), Gavialidium philippinum Bolívar, 1887 syn. nov. (of Platygavialidium productum comb. nov.), Hexocera Hancock, 1915 syn. nov. (of Scelimena), Paracriotettix Liang, 2002 syn. nov. (of Scelimena), Paracriotettix zhengi Liang, 2002 syn. nov. (of Scelimena melli), Scelimena mellioides Deng, 2016 syn. nov. (of Scelimena melli), Scelimena wuyishanensis Deng, 2016 syn. nov. (of Platygavialidium sinicum). The genus Scelimena is divided into six species groups. Eucriotettix neesoon Tan Storozhenko nom. nov. is new name for homonym Eucriotettix guentheri Tan Storozhenko, 2017. Finally, a tabular key to 15 Scelimenini genera, based on 16 morphological characters, is presented.
  9. An integrative taxonomic review of the agamid genus Bronchocela (Kuhl, 1820) from Peninsular Malaysia with descriptions of new montane and insular endemics
    Grismer LL, Wood PL, Lee CH, Quah ES, Anuar S, Ngadi E, et al.
    Zootaxa, 2015 Apr 20;3948(1):1-23.
    PMID: 25947760 DOI: 10.11646/zootaxa.3948.1.1
    An integrative taxonomic analysis is used to identify and describe two new species of the agamid genus Bronchocela (Kuhl) from Peninsular Malaysia: an upland species B. shenlong sp. nov. from Bukit Larut, Perak in the Bintang Mountain Range and Parit Falls, Cameron Highlands, Pahang in the Titiwangsa Mountain Range and an insular species, B. rayaensis sp. nov., from Pulau Langkawi, Kedah off the northwest coast on the border with Thailand. Both species are diagnosed from each other and all other species of Bronchocela on the basis of body shape, scale morphology, and color pattern. The analysis also demonstrates the remarkable genetic similarity of B. cristatella (Kuhl) throughout 1120 km of its range from northern Peninsular Malaysia to western Borneo despite its highly variable coloration and pattern. The two new species are appended to a rapidly growing list of newly described lizard species (60 to date) from Peninsular Malaysia tallied within the last decade.
  10. The phylogenetic relationships of a new Stream Toad of the genus Ansonia Stoliczka, 1870 (Anura: Bufonidae) from a montane region in Peninsular Malaysia
    Davis HR, Grismer LL, Klabacka RL, Muin MA, Quah ES, Anuar S, et al.
    Zootaxa, 2016 Apr 12;4103(2):137-53.
    PMID: 27394624 DOI: 10.11646/zootaxa.4103.2.4
    Twelve species of Ansonia occur on the Thai-Malay peninsula, of which, five from Peninsular Malaysia, form a monophyletic group. One of these, A. jeetsukumarani, is endemic to the Titiwangsa Mountain Range, in which, we discovered a new population of Ansonia that is not A. jeetsukumarani or even its closest relative. Based on morphology, color pattern, and molecular phylogenetic analyses using the mitochondrial genes 12s and 16s rRNA, we have determined that this new species, A. smeagol sp. nov., forms the sister lineage to an upland, monophyletic group composed of A. jeetsukumarani, A. lumut, A. malayana, and A. penangensis. We have noted similar biogeographic patterns in other taxa from the Titiwangsa Mountain Range in a number of upland lineages in Peninsular Malaysia. We hypothesize that the phylogeographic structure of these upland populations is a result of stochastic processes stemming from interaction of climate-driven forest dynamics and life histories.
  11. Two new Bent-toed Geckos of the Cyrtodactylus pulchellus complex from Peninsular Malaysia and multiple instances of convergent adaptation to limestone forest ecosystems
    Grismer LL, Wood PL, Anuar S, Grismer MS, Quah ES, Murdoch ML, et al.
    Zootaxa, 2016 Apr 25;4105(5):401-29.
    PMID: 27394789 DOI: 10.11646/zootaxa.4105.5.1
    A new species of limestone cave-adapted gecko of the Cyrtodactylus pulchellus complex, C. hidupselamanya sp. nov., is described from an isolated karst formation at Felda Chiku 7, Kelantan, Peninsular Malaysia. This formation is scheduled to be completely quarried for its mineral content. From what we know about the life history of C. hidupselamanya sp. nov., this will result in its extinction. A new limestone forest-adapted species, C. lenggongensis sp. nov., from the Lenggong Valley, Perak was previously considered to be conspecific with C. bintangrendah but a re-evaluation of morphological, color pattern, molecular, and habitat preference indicates that it too is a unique lineage worthy of specific recognition. Fortunately C. lenggongensis sp. nov. is not facing extinction because its habitat is protected by the UNESCO Archaeological Heritage of the Lenggong Valley due to the archaeological significance of that region. Both new species can be distinguished from all other species of Cyrtodactylus based on molecular evidence from the mitochondrial gene ND2 and its flanking tRNAs as well as having unique combinations of morphological and color pattern characteristics. Using a time-calibrated BEAST analysis we inferred that the evolution of a limestone habitat preference and its apparently attendant morphological and color pattern adaptations evolved independently at least four times in the C. pulchellus complex between 26.1 and 0.78 mya.
  12. Three new species and a new record of the spider genus Mallinella Strand, 1906 from Brunei (Araneae, Zodariidae)
    Dankittipakul P, Koh JK, Singtripop T
    Zootaxa, 2014;3826(2):377-85.
    PMID: 24990054 DOI: 10.11646/zootaxa.3826.2.7
    This article is the first formal record of the genus Mallinella Strand, 1906 in Brunei Darussalam. Four Mallinella species are documented. Mallinella merimbunenis sp. nov., M. myrmecophaga sp. nov., and M. platyrhyncha sp. nov. are newly described. The females of M. bigemina Dankittipakul, Jocqué & Singtripop, 2012 are here recorded from Brunei for the first time. The latter species was previously known only from an evergreen hill forest at 2,000 m elevation at Mt. Kinabalu of Kinabalu Park in Sabah.
  13. 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.

  14. Systematics of the combtooth blenny clade Omobranchus (Blenniidae: Omobranchini), with notes on early life history stages
    Gibbs S, Hundt PJ, Nelson A, Egan JP, Tongnunui P, Simons AM
    Zootaxa, 2018 Jan 03;4369(2):270-280.
    PMID: 29689891 DOI: 10.11646/zootaxa.4369.2.7
    The combtooth blenny (Blenniidae) genus Omobranchus contains small, cryptobenthic fishes common to nearshore habitats throughout the Indo-West Pacific. Recent molecular systematic studies have resolved Omobranchus as monophyletic but little research has been done to resolve species-level relationships. Herein, phylogenetic analyses of one mitochondrial (CO1) and four nuclear (ENC1, myh6, sreb2, and tbr1) genes provide evidence for the monophyly of Omobranchus and support for the elongatus and banditus species group. Sampling of multiple individuals from widespread species (O. ferox, O. punctatus, and O. elongatus) suggested that the Thai-Malay Peninsula is a phylogeographic break that may be a historic barrier to gene flow. Additionally, common meristics and other morphological characters are used to describe an early life history stage of O. ferox and O. punctatus.
  15. Review of the genera Berlesia Canestrini, 1884, and Katydiseius Fain amp; Lukoschus, 1983, the subfamily Katydiseiinae Fain amp; Lukoschus, 1983, and their family group relationships (Acari: Mesostigmata: Gamasina), with description of three new species parasitic on gryllacridid crickets (Orthoptera)
    Lindquist EE, Oconnor BM, Shaw MD, Sidorchuk EA
    Zootaxa, 2020 Sep 28;4857(1):zootaxa.4857.1.4.
    PMID: 33056345 DOI: 10.11646/zootaxa.4857.1.4
    The gamasine genus Berlesia Canestrini, 1884, is revived and further diagnosed, based on descriptions of adult females, males and nymphs of three new species (B. hospitabilis sp. nov., B. multisetosa sp. nov., B. vorontsovi sp. nov.) ectoparasitic on raspy crickets of three genera of Gryllacrididae (Ensifera) from Australia and the Philippines. A tight sister relationship of Berlesia with the monobasic genus Katydiseius Fain Lukoschus, 1983, known only from a pseudophylline katydid in Malaysia, is proposed. The subfamily Katydiseiinae Fain Lukoschus, 1983 (previously included in the family Otopheidomenidae in the superfamily Phytoseioidea) is redefined to include only those two genera, and moved to the dermanyssoid family Laelapidae, while its previously other monobasic genus, Eickwortius Zhang, 1995, is retained tentatively in the family Otopheidomenidae. Among other taxa relevant to Katydiseiinae reviewed here, Berlesia cultrigera Berlese, 1910a is transferred to the genus Orthopteroseius Mo, 1996, at present Otopheidomenidae, as Orthopteroseius cultrigerum (Berlese) comb. nov., and Berlesia nuda Berlese, 1910b is transferred to the genus Prasadiseius Wainstein, 1972, at present Otopheidomenidae, as Prasadiseius nudum (Berlese) comb. nov. A key to the two genera and five species recognized as belonging in Katydiseiinae is presented. Notable morphological traits of Berlesia, including only deutonymphs equipped with well-developed claws and males with dimorphically more elongated salivary stylets, are discussed. The one known life cycle of a species of Berlesia, B. hospitabilis sp. nov., includes protonymphipary, followed by a fully functioning deutonymph, and male copulation with pharate females-traits, rarely or not known among gamasine mite associates of invertebrates. The possible significance of elongate spermatodactyls and male reduced feeding are explored.
  16. Ciimaerocyon gen. nov., a morphologically aberrant myrmecophilous genus of water scavenger beetle (Coleoptera: Hydrophilidae: Sphaeridiinae)
    Fikáček M, Maruyama M, Vondráček D, Short AE
    Zootaxa, 2013;3716:277-88.
    PMID: 26106776
    Anew hydrophilid genus Chimaerocyon gen. nov. containing two species, C. shimadai sp. nov. (Malaysia: Pahang) and C. sumatranus sp. nov. (Indonesia: Sumatra), is described. Specimens of C. shimadai were collected from brood cells in anest of Pheidole singaporensis Özdikmen, 2010. The biology of C. sumatranus remains unknown. A molecular phylogeny based on four genes (cox1, cox2, 18S and 28S) supports the placement of the genus as deeply nested within the Cercyon-group of the tribe Megasternini. This position is supported by the subdistal position of the median spur in the hind wing (unique to Megasternini) and the presence of sucking disc on male maxilla (unique for Megastemini+Sphaeridiini). The remaining external morphology differs substantially from other representatives of Megasternini. The hypothesis that the aberrant morphology of Chimaerocyon gen. nov. is a consequence of myrmecophily is discussed.
  17. Revision of the Oriental species of Calleida Latreille (sensu lato). Part 1: Introduction, groups of species, and species of six species groups (Coleoptera: Carabidae: Lebiini)
    Casale A, Shi H
    Zootaxa, 2018 Jun 29;4442(1):1-42.
    PMID: 30313981 DOI: 10.11646/zootaxa.4442.1.1
    This revision focuses on the genus Calleida Latreille, 1824 (in the widest sense) in the Oriental Region, previously treated as genus or subgenus Callidiola Jeannel, 1949. In the present contribution, as first part of a series of revisions of the Asiatic Calleida species, we define nine species groups including all known Asiatic species, based on external features and morphological characters of male and female genitalia. A key for the identification of all nine species groups is provided, along with diagnostic characters, included species, geographical distribution, and brief discussion on monophyly and relationships for each species group. In particular, the present contribution deals with species of six small species groups, including eleven species in total, for which keys to all known species, descriptions, distribution maps, habitus images and genitalia illustrations are provided.Five new species are described: Calleida gressittiana Casale Shi, sp. n. (type locality: Kinabalu, Sabah, Borneo), Calleida puncticollis Shi Casale, sp. n. (type locality: Zigui, Hubei), Calleida jelineki Casale Shi, sp. n. (type locality: Coimbatore, India), Calleida viet Casale Shi, sp. n. (type locality: Vung Tau, Vietnam), Calleida borneensis Shi Casale, sp. n. (type locality: Sabah, Borneo). Lectotypes for five taxa are designated. One synonymy is newly proposed: Calleida lieftincki Louwerens junior synonym of Calleida corporaali Andrewes, syn. nov.

    The armored harvestman family Assamiidae (Arachnida: Opiliones: Laniatores) is widely distributed throughout the Old World tropics, specifically throughout tropical Asia and Central Africa. However, the systematics and intrafamilial relationships of the group remain poorly understood. This can be largely attributed to the complicated taxonomic history of the group, which is exemplified by poorly supported subfamily classifications and the prevalence of monotypic genera. Here, we describe four new species of the formerly monotypic genus Paktongius Suzuki, 1969, using specimens collected from Laos, Thailand, and West Malaysia, suggesting a degree of microendemism within the group, which underscores the need for greater sampling of the southeast Asian arachnofauna. Recent phylogenetic analysis has also suggested that Mysorea thaiensis Suzuki, 1985 nests within a clade composed of Paktongius distinctus Suzuki, 1969 and the species described herein (P. suzukii sp. nov., P. spiculosus sp. nov., P. paritensis sp. nov., P. furculus sp. nov.). We therefore transfer Mysorea thaiensis to Paktongius (P. thaiensis comb. nov.). We also comment on the unique morphology of this highly derived group of harvestmen, which appears to suggest convergent evolution of the gonyleptoid-like morphology, complete with the characteristic exaggerated leg four coxae and laterally expanded scutum.
