  3. Cheсklist of gastropod molluscs in mangroves of Khanh Hoa province, Vietnam
    Zvonareva S, Kantor Y
    Zootaxa, 2016 Sep 12;4162(3):401-37.
    PMID: 27615983 DOI: 10.11646/zootaxa.4162.3.1
    Gastropod molluscs are one of the most important components of mangrove ecosystem. Mangroves in Central Vietnam have a rather limited distribution due to peculiarities of the coastline morphology and presently their fauna remains understudied. Extensive surveys were conducted in both natural vegetation and artificial mangrove plantations in several localities in Nha Trang Bay from 2005 to 2015. In total 65 species of gastropod molluscs were found alive, 17 of which can be considered as predominantly mangrove-associated. An illustrated guide is provided, with short synonymies and data on ecology and distribution. The recorded molluscan diversity is compared with published data on mangrove gastropods in different regions of the Indo-Pacific. Total species number and the proportion of mangrove-associated species are similar to studied faunas in Hong Kong, Malaysia and Thailand, but the diversity is much lower than that of the mangal fauna of the Philippines.

  4. On the taxonomy and phylogeny of the skinks Lipinia sekayuensis Grismer, Ismail, Awang, Rizal, & Ahmad and Lipinia surda Boulenger from Peninsular Malaysia
    Grismer LL, Wood PL, Syafiq MF, Badli-Sham BH, Rizal SA, Ahmad AB, et al.
    Zootaxa, 2016 Aug 02;4147(1):59-66.
    PMID: 27515603 DOI: 10.11646/zootaxa.4147.1.3
    An integrative taxonomic analysis based on additional specimens and color photographs of Lipinia sekayuensis and additional color photographs of L. surda from Pulau Tioman and the Gunung Panti Forest Reserve, Peninsular Malaysia confirm the previous hypotheses that L. sekayuensis is a valid species and is the sister species of L. surda. The two species share a 12.8% sequence divergence between them.

  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. Revision of the genus Morphosphaera Baly (Coleoptera: Chrysomelidae: Galerucinae)
    Lee CF, Bezdĕk J
    Zootaxa, 2016 Oct 28;4179(1):1-41.
    PMID: 27811689 DOI: 10.11646/zootaxa.4179.1.1
    The genus Morphosphaera Baly, 1861 is revised. Eleven species are considered as valid, including, M. takizawai sp. nov. (Mt. Basor, 90 km N of Gua Musang, Malaysia, W. Kelantan), described from Malaysia and Indonesia. Color photos of habitus and drawings of diagnostic characters from eleven species are presented. The following synonymies are proposed: M. sodalis Chen, 1935 and M. brunnea Maulik, 1936 are junior synonyms of M. albipennis Allard, 1889; M. margaritacea Laboissière, 1930, M. viridipennis Laboissière, 1930, and M. prava Maulik, 1936 are junior synonyms of M. coomani Laboissière, 1930; M. gracilicornis Chen, 1963 is a junior synonym of M. maculicollis Baly, 1861; M. cavaleriei Laboissière, 1930, M. cincticollis Laboissière, 1930, M. marginata Laboissière, 1930, M. purpurea Laboissière, 1930, M. gingkoae Gressitt & Kimoto, 1963, and M. metallescens Gressitt & Kimoto, 1963 are junior synonyms of M. sumatrana Jacoby, 1886. The type material of M. impunctata Allard, 1890 from the Philippines was not found and its taxonomic status remains uncertain. Morphosphaera peregrina Weise, 1913 is transferred to the genus Borneola Mohamedsaid, 1998 nov. comb. A neotype is designated for Chrysomela japonica Hornstedt, 1788. Lectotypes are designated for the following species: Adorium chrysomeloides Bates, 1866, A. japonicum Baly, 1874, Morphosphaera albipennis Allard, 1889, M. bimaculata Chûjô, 1938, M. caerulea Jacoby, 1896, M. cavaleriei Laboissière, 1930, M. collaris Laboissière, 1930, M. formosa Laboissière, 1930, M. marginata Laboissière, 1930, M. montivaga Maulik, 1936, M. prava Maulik, 1936, M. purpurea Laboissière, 1930, M. sumatrana Jacoby, 1886, M. viridipennis Laboissière, 1930, and Galerucida simplex Weise, 1922.

  7. Two new whiprays, Maculabatis arabica sp. nov. and M. bineeshi sp. nov. (Myliobatiformes: Dasyatidae), from the northern Indian Ocean
    Manjaji-Matsumoto BM, Last PR
    Zootaxa, 2016 Jul 28;4144(3):335-53.
    PMID: 27470860 DOI: 10.11646/zootaxa.4144.3.3
    Two new medium-sized whiprays, Maculabatis arabica sp. nov. and M. bineeshi sp. nov., are described from specimens collected in coastal habitats of the northern Indian Ocean, off India and Pakistan. Both species superficially resemble M. randalli (Last, Manjaji-Matsumoto & Moore), and appear to have been confused with a more widely distributed whipray M. gerrardi Gray, and another undescribed species from the Indian Ocean. Maculabatis arabica sp. nov. (attains at least 63 cm DW) is diagnosed by a combination of external characters, i.e. morphometrics (e.g. relatively short disc, narrow interspaces between paired structures on the head), squamation (relatively slow denticle development and a characteristic denticle band shape), plain dorsal disc coloration (rather than spotted), and tail light brown and banded beyond the caudal sting in juveniles but almost plain in adults. Maculabatis bineeshi sp. nov. (attains at least 66 cm DW) is diagnosed by a combination of characters, i.e. morphometrics (e.g. suboval to weakly rhombic disc in young), squamation (rapid denticle development and broad denticle band with margins truncate near pectoral-fin insertions), plain dorsal disc coloration (no white spots), and a dark blackish tail (especially in young) with weakly mottled banding on its dorsal surface beyond the caudal sting. Maculabatis arabica sp. nov. appears to be confined to the Arabian Sea (from Pakistan to western India), whereas M. bineeshi sp. nov. occurs in the Arabian Sea (off Pakistan and northwestern India) and in the Bay of Bengal (confirmed off Odisha, eastern India).

    PMID: 30313214 DOI: 10.11646/zootaxa.4433.3.5
    The newly defined Agrilus gratiosus species-group comprising ten species from the Oriental region is revised. A key to species is provided and complemented with illustrations of habitus, genitalia and type specimens. The following seven new species are described: Agrilus cultus sp. nov. (Laos); A. oudomxai sp. nov. (Laos); A. pergratus sp. nov. (Malaysia); A. pluridens sp. nov. (Laos, Thailand); A. pubinotus sp. nov. (Indonesia: Sumba Island); A. siberuticola sp. nov. (Indonesia: Siberut Island) and A. signipes sp. nov. (Vietnam). Agrilus makiharai Tôyama, 1987 is considered conspecific with A. bacchus Kerremans, 1913 and therefore the name makiharai syn. nov. is a junior subjective synonym of the name bacchus.

  11. Taxonomy, phylogeny, and distribution of Bronchocela rayaensis (Squamata: Agamidae) on the Thai-Malay Peninsula
    Grismer LL, Wood PL, Aowphol A, Cota M, Murdoch ML, Aguilar C, et al.
    Zootaxa, 2016 Mar 16;4092(3):414-20.
    PMID: 27394463 DOI: 10.11646/zootaxa.4092.3.6
    An integrative taxonomic analysis used to identify a new population of Bronchocela from Phuket Island, Thailand indicates it is conspecific with B. rayaensis from the Langkawi Archipelago of northwestern Peninsular Malaysia. An additional specimen photographed from Khura Buri District, Phang-nga Province is also considered to be B. rayaensis and represents a northern range extension of 295 km from the Langkawi Archipelago.

  12. Phylogenetic relationships of geckos of the Hemiphyllodactylus harterti group, a new species from Penang Island, Peninsular Malaysia, and a likely case of true cryptic speciation
    Cobos A, Grismer LL, Wood PL, Quah ES, Anuar S, Muin MA
    Zootaxa, 2016 May 03;4107(3):367-80.
    PMID: 27394826 DOI: 10.11646/zootaxa.4107.3.5
    An integrative taxonomic analysis based on the mitochondrial gene ND2 and its flanking tRNAs, morphology, and color pattern indicates that a newly discovered gecko described herein as Hemiphyllodactylus cicak sp. nov. from Penang Hill on the Island of Penang, Peninsular Malaysia is a member of the H. harterti group. Hemiphyllodactylus cicak sp. nov. is most closely related to the clade composed of the sister species H. harterti from Bukit Larut, Perak in the Bintang Mountain Range and H. bintik from Gunung Tebu, Terengganu from the Timur Mountain Range. These three allopatric species form a monophyletic group that extends approximately 270 km across three isolated mountain ranges in northern Peninsular Malaysia. The molecular analysis also indicates that H. titiwangsaensis from the Titiwangsa Mountain Range is composed of three genetically distinct allopatric populations. The southern two populations from Fraser's Hill and Genting Highlands, Pahang have an uncorrected pairwise sequence divergence of 3.5% whereas these two populations have 12.4 and 12.8 % sequence divergences, respectively, from the northern population at Cameron Highlands, Pahang. Although the high sequence divergence clearly distinguishes the southern two populations from the former as a different species, all three populations are morphologically indistinguishable, leading to the hypothesis of a true, cryptic speciation event.

  14. Revision of the grasshopper genus Sedulia Stål, 1878 (Acrididae: Catantopinae) from Malay Peninsula
    Tan MK, Robillard T, Kamaruddin KN
    Zootaxa, 2016 May 02;4107(2):255-66.
    PMID: 27394817 DOI: 10.11646/zootaxa.4107.2.7
    Southeast Asia is a highly biodiverse region with many species of grasshoppers described since the 19th century. Historical species descriptions are however often not comprehensive and do not meet the modern criteria of taxonomy. Previously used characters for identification need to be re-examined. Here, we aim to revise the taxonomy of the grasshopper genus Sedulia Stål, 1878. Using morphology and simple morphometry, we compared and investigated interspecific and intraspecific variations among the two species of Sedulia. We also redescribed both species and constructed a key to species and closely related genera.

  15. A new species and locality record for Pseudopsyra katydid (Orthoptera: Phaneropterinae)
    Tan MK, Dawwrueng P, Artchawakom T
    Zootaxa, 2017 Feb 13;4231(4):zootaxa.4231.4.12.
    PMID: 28264411 DOI: 10.11646/zootaxa.4231.4.12
    Pseudopsyra is a genus of Phaneropterinae katydid (Orthoptera: Tettigoniidae), currently comprising of four species - two species each from southern China and Peninsular Malaysia (Hebard, 1922; Liu & Kang, 2006; Tan & Kamaruddin, 2013, 2014). The revision of Pseudopsyra by Liu & Kang (2006) provided a redescription of the genus, a new diagnosis and a key to known species. Subsequently, more surveys were conducted in Peninsular Malaysia and yield another species, representing the lowest latitudinal limits of this genus thus far (Tan & Kamaruddin, 2013). Continued surveys between the upper and lower latitudinal limits of the genus yield a new species: Pseudopsyra taksini sp. nov. from the Sakaerat Biosphere Reserve, Thailand. The orthopteran diversity at Sakaerat Biosphere Reserve remains understudied with numerous new species described recently, including other genus of Phaneropterinae (Tan & Artchawakom, 2014; Tan et al., 2015). With emphasis of using sexual parts for evidence of reproductive isolation in species delimitation, the discovery of a new species of Pseudopsyra also represents the first record of the genus from Thailand. It is not surprising that more undescribed species of Pseudopsyra can be found across the Indo-China region.

  16. A new species of Leptolalax from Sarawak, Western Borneo (Anura: Megophryidae)
    Matsui M, Zainudin R, Nishikawa K
    Zoolog Sci, 2014 Nov;31(11):773-9.
    PMID: 25366161 DOI: 10.2108/zs140137
    A new megophryid species is described from southwestern Sarawak, Malaysian Borneo. In appearance, Leptolalax marmoratus sp. nov. is most similar to L. hamidi also from southwestern Sarawak, but differs from it by mtDNA sequence, larger body size, and higher dominant frequency of advertisement call. The assumption that more than one species of Leptolalax coexist at one locality in Borneo is supported. The finding of the new species raises the species number of Leptolalax known from Borneo to nine, and the island is thought to be one of the diversification centers of the genus.

    PMID: 19719411 DOI: 10.2108/zsj.26.579
    A new microhylid, Kalophrynus yongi, Is described from the Cameron Highlands of Peninsular Malaysia. Morphologically, the new species differs from all known congeners by having a very stout forelimb with a humeral spine in males. Acoustically, it resembles K. baluensis and K. heterochirus and sharply differs from K. interlineatus, K. pleurostigma, K. palmatissimus, and K. nubicola.

  18. Taxonomic relationships of Ansonia anotis Inger, Tan, and Yambun, 2001 and Pedostibes maculatus (Mocquard, 1890), with a description of a new genus (Amphibia, Bufonidae)
    Matsui M, Yambun P, Sudin A
    Zoolog Sci, 2007 Nov;24(11):1159-66.
    PMID: 18348617 DOI: 10.2108/zsj.24.1159
    Examination of types and recently collected specimens revealed that Ansonia anotis Inger, Tan, and Yambun, 2001 and Pedostibes maculatus (Mocquard, 1890), both described from Kinabalu, Sabah, Malaysia, are hardly differentiated morphologically. Analyses of a total of 2,427 bp of the 12S rRNA, tRNA(val), and 16S mitochondrial rRNA genes revealed that the two species are very close genetically. Thus A. anotis is regarded as conspecific and is synonymized with P. maculatus. Genetically, this species proved to form a lineage distinct from other bufonids from Southeast Asia, including species of Ansonia and Pedostibes. Because the species has also some unique morphological traits different from known bufonid genera, we propose to establish a new genus for Nectophryne maculata Mocquard, 1890.

  19. Structure and development of free neuromasts in barramundi, Lates calcarifer (Block)
    Mukai Y, Chai LL, Shaleh SR, Senoo S
    Zoolog Sci, 2007 Aug;24(8):829-35.
    PMID: 18217491
    This study was conducted to clarify the development of free neuromasts with growth of the barramundi, Lates calcarifer. A pair of free neuromasts was observed behind the unpigmented eyes in newly hatched eleutheroembryos with a mean total length of 1.93 mm, and two-hour-old eleuthero-embryos could respond to an approaching pipette. At 2 days after hatching, the egg yolk sac was mostly consumed, the eyes were pigmented, and the larvae commenced feeding on rotifers. Free neuromasts increased in number with growth and commenced developing into canal neuromasts in barramundi 15 days old with a mean total length of 8.07 mm. The average length of the major axis of the trunk free neuromasts attained approximately 12.9-15.5 microm, and the number of sensory cells was 15.4-17.5 at 15-20 days old. Developed cupulae of free neuromasts were observed in 1-day-old eleutheroembryos. The direction of maximum sensitivity of free neuromasts, determined from the polarity of the sensory cells, coincided with the minor axis of the lozenge-shaped outline of the apical surface of the free neuromasts. The polarity of trunk neuromasts was usually oriented along the antero-posterior axis of the fish body, but a few had a dorso-ventral direction. On the head, free neuromasts were oriented on lines tangential to concentric circles around the eye.

  20. Allozyme variation in the camaenid tree snails Amphidromus atricallosus (Gould, 1843) and A. inversus (Müller, 1774)
    Prasankok P, Ota H, Toda M, Panha S
    Zoolog Sci, 2007 Feb;24(2):189-97.
    PMID: 17409732
    We examined allozyme variation in two camaenid tree snails, Amphidromus atricallosus and A. inversus, across two principal regions of Thailand and from Singapore, plus for A. inversus, one site in peninsular Malaysia. Using horizontal starch gel electrophoresis, 13 allozyme loci (11 polymorphic) were screened for A. atricallosus and 18 (5 polymorphic) for A. inversus. Heterozygosity was higher in A. atricallosus (Hexp=0.018-0.201, mean=0.085) than in A. inversus (Hexp=0-0.023, mean= 0.002). Genetic heterogeneity among samples was higher in A. inversus (Fst=0.965) than in A. atricallosus (Fst=0.781). Within A. atricallosus, populations were more differentiated in southern Thailand (Fst=0.551) than in eastern Thailand (Fst=0.144). The high Fst and low Hexp in populations of A. inversus suggest that this species is likely to have experienced a series of strong bottlenecks, perhaps occurring chiefly on offshore continental-shelf islands. The low Fst values of A. atricallosus in eastern Thailand suggest frequent gene flows among populations in this region. The southern and eastern samples of A. atricallosus exhibited fixed allele differences at four loci and great genetic distance (Nei's D=0.485-0.946), suggesting that these two samples may actually represent, or else be evolving into, separate species.
