The wolf spider genus Artoria Thorell, 1877 is a common group in Australasia, currently including 41 species from Australia, three from New Zealand and four from Pacific islands (Framenau Baehr 2018; Word Spider Catalog 2019). This does not, however, comprise the whole distribution of the genus. The type species, A. parvula Thorell, 1877 has been recorded from China, Philippines, Indonesia (Sulawesi) and Australia (Northern Territory). An endemic species, A. ligulacea (Qu, Peng Yin, 2009) was described from Yunnan, China. This indicates that there must be some undescribed species from Southeast Asian countries. A recent collecting expedition to Malaysia confirms this hypothesis. Two species of Artoria were found, the type species, A. parvula from East and West Malaysia and a new species, A. weiwei sp. nov. from East Malaysia. In this study, we illustrate the former and describe for the first time the latter species.
To date, 26 species of Theloderma have been described and all are distributed throughout Southeast Asia from Assam in northeastern India to Myanmar, Indochina, the Malay Peninsula, and the islands of the Greater Sundas: Sumatra and Borneo (Frost 2019). The tadpoles of only 12 species have been described and published: T. asperum (Boulenger); T. auratum Poyarkov, Kropachev, Gogoleva Orlov; T. bicolor (Bourret); T. corticale (Boulenger); T. gordoni Taylor; T. horridum (Boulenger); T. leave (Smith); T. moloch (Annandale); T. nebulosum Rowley, Le, Hoang, Dau Cao; T. palliatum Rowley, Le, Hoang, Dau Cao; T. stellatum Taylor; T. vietnamense Poyarkov, Orlov, Moiseeva, Pawangkhanant, Ruangsuwan, Vassilieva, Galoyan, Nguyen Gogoleva (Boulenger 1903; Annandale 1912; Wassersug et al. 1981; Inger et al. 1999; Leong Lim 2003; Inthara et al. 2005; Rowley et al. 2011; Gawor et al. 2012; Orlov et al. 2012; Poyarkov et al. 2015; Kropachev et al. 2018).
This revision of the bee genus Bathanthidium Mavromoustakis, 1953, treats 12 species, with 11 recorded from China, including Bathanthidium fengkaiense Niu Zhu, sp. nov.. Two species are proposed as new combinations in genus Bathanthidium: Anthidium (s. str.) bicolor Wu, 2004, A. (s. str.) monganshanensis Wu, 2004. The two new combinations (B. bicolor, B. monganshanense) are in Bathanthidium (Manthidium), previously considered to include only the type species from Burma and Laos (published records from northeastern India and Malaysia are based on misinterpreted localities). Trachusa (Paraanthidium) concavum (Wu, 1962) and Stelis siamensis Friese, 1925 are synonymized with B. binghami (Friese, 1901). Bathanthidium circinatum Wu, 2004 is transferred to Pseudoanthidium Friese forming the new combination P. (s. str.) circinatum (Wu, 2004). The distribution of each species is given, new distribution sites are marked by asterisk (*) especially. Our results confirm that the genus Bathanthidium has higher species diversity than previously documented and that this diversity is centered in China.
A new species of Ansonia is described from the Shan Plateau of Myanmar based on an integrative taxonomic analysis that differentiates it from all other congeners. Molecular phylogenetic analyses based on the mitochondrial genes 12S and 16S rRNA and tRNA-val recover A. kyaiktiyoensis sp. nov. as the sister species to A. inthanon from Thailand but differs from it and other congeners by at least a 5.0% sequence divergence. It is further differentiated by the following combination of morphological characters: (1) maximum SVL 24 mm in males and females; (2) first finger shorter than second; (3) absence of interorbital and tarsal ridges; (4) presence of light-coloured interscapular spot; (5) presence of yellow rictal tubercle; (6) absence of wide, light-coloured patch below eye; (7) presence of large, discrete, bright-yellow submandibular spots along the underside of lower jaw; (8) iris yellow-gold; (9) presence of markings on the snout consisting of streaks below the eye to the lip, and on the canthus rostralis to the nostril; (10) dorsum grey-brown with orange-beige spots, a dark-brown X-shaped marking on the back surrounding the interscapular spot, and dark-coloured markings on rump; (11) fore- and hind limbs with orange-beige cross-bars; and (12) venter light-gray with yellow spotting, especially near flanks and underside of hind limbs. Ansonia kyaiktiyoensis sp. nov. is the westernmost known record for the genus and the only species west of the Salween Basin. Its discovery echoes the increasing number of herpetological discoveries being made in upland regions fringing the Ayeyarwady and Salween Basins.
Asian herminiine moths of the Herminia decipiens complex are revised and five allopatric species are recognized, i.e. Herminia decipiens (Hampson, 1898) in Nilgiri Hills, Khasi Hills, South China, Indochina, Malay Peninsula, H. terminalis (Wileman, 1915) in Taiwan, H. yuksam sp. nov. in East Nepal, Sikkim, H. borneo sp. nov. in Borneo and H. amamioshima sp. nov. in Amami-oshima Is., Shimo-Koshikijima Is. and South Kyushu (Kagoshima). Key to all species is given.
Additions and corrections to original description of Umbrageocoris Kóbor, 2019 are provided along with the description of a new species and its two subspecies: Umbrageocoris maai maai ssp.n. from Borneo and the Malay Peninsula and Umbrageocoris maai timorensis ssp.n. from Timor. Key to known species and distribution maps included.
Simulium (Gomphostilbia) marosense sp. nov. is described based on adults, pupae and mature larvae from Sulawesi, Indonesia. This new species is placed in the Simulium duolongum subgroup of the S. batoense species-group, representing the ninth member for the subgroup in Sulawesi. This new species is characterized by a narrow female frons and pupal gill with eight filaments, of which two filaments of the ventral pair are 1.9-3.0 times as long as the six other filaments. Taxonomic notes are provided to distinguish this new species from related species.
Two new intertidal oribatid mite species from the Indo-pacific region are described. Indopacifica iohanna sp. n. was found on the coasts of the Philippines and can be distinguished from its congeners by the lack of a ventral tooth on the claws. The larva and nymphs of this species show the same type of plication and setation typical for juveniles of other selenoribatid mites. Indopacifica mauritiana sp. n. was discovered on the coast of Mauritius and can be separated from its congeners by possessing only vestigial lamellar setae. A morphometric comparison of these two species and Indopacifica pantai from Thailand and Malaysia showed a clear separation between the three species. The known distribution of the genus Indopacifica stretches now from Mauritius in the West to the Philippines in the East and further occurrences within this area should be expected.
A review of the taxonomic status of the Smooth Slug Snake (Asthenodipsas laevis) in Borneo resulted in the discovery of two previously unrecognised species from the highlands of Sabah, East Malaysia. Asthenodipsas jamilinaisi sp. nov. and A. stuebingi sp. nov. are presumed to be closely related to A. laevis based on similarities in pholidosis and patterning but can be separated from A. laevis by their dorsal scale rows of 15/15/15 vs 15/15/13 and the presence of a sharp vertebral keel. Asthenodipsas jamilinaisi sp. nov. can be further differentiated from A. stuebingi sp. nov. by the greatly enlarged size of the vertebral scales, higher number of ventrals in males (173-175 vs 165), higher number of subcaudals (53 vs 35-47) and colour pattern (dark overall with indistinct bands vs lighter head and body with clear, distinct bands and a dark neck patch). The discovery highlights the need for more careful examination of much of the herpetofauna of Borneo that still remains underestimated and understudied. There is an urgent need for continued surveys into its diversity and the collection of genetic material for integrated taxonomic revisions.
An integrative taxonomic analysis of the Ptychozoon lionotum group across its range in Indochina and Sundaland recovers P. lionotum sensu lato Annandale, 1905 as paraphyletic with respect to P. popaense Grismer, Wood, Thura, Grismer, Brown, Stuart, 2018a and composed of four allopatric, genetically divergent, ND2 mitochondrial lineages. Multivariate and univariate analyses of continuous and discrete morphological and color pattern characters statistically and discretely diagnose each lineage from one another and together, with maximum likelihood and Bayesian inference analyses, provide the foundation for the recognition of each lineage as a new species-hypotheses corroborated with a Generalized Mixed Yule Coalescent species delimitation analysis. Ptychozoon cicakterbang sp. nov. ranges throughout Peninsular Malaysia to Pulau Natuna Besar, Indonesia; P. kabkaebin sp. nov. is endemic to northern and central Laos; and P. tokehos sp. nov. ranges from southern Thailand south of the Isthmus of Kra northward to Chiang Mai, fringing the Chao Phraya Basin and ranging southward through Cambodia to southern Vietnam. Ptychozoon lionotum sensu stricto ranges from northwestern Laos through southern Myanmar to eastern India. The phylogeographic structure within each species varies considerably with P. lionotum s.s. showing no genetic divergence across its 1,100 km range compared to P. cicakterbang sp. nov. showing upwards of 8.2% sequence divergence between syntopic individuals. Significant phylogeographic structure exists within P. tokehos sp. nov. and increased sampling throughout Thailand may require additional taxonomic changes within this species.
The pselaphine genus Sathytes Westwood is represented in Borneo by a single species. In this paper we describe four new species: S. borneoensis sp. nov., S. liuyei sp. nov., S. larifuga sp. nov., and S. shihongliangi sp. nov. All new species were collected by light traps in Sabah, and show unique combinations of male sexual characters that lead to ready species discriminations. A key to Sathytes species from Borneo is appended.
Accurate identification of mosquitoes is crucial for the management and control of vector species. Although Singapore is a tropical country with high mosquito diversity, there are no identification keys specific to its mosquito fauna. An illustrated identification key to the genera of the adult female mosquitoes of Singapore is presented. Twenty genera are characterized and two genera found in Malaysia, Culiseta and Topomyia, are also included. The key will aid non-taxonomically trained operational officers in adult mosquito identification. The key to the genera provides the first crucial step in the process to species identification.
A key is provided to 13 species of Haplothrips recorded from Malesia, the tropical biogeographic region that extends from Peninsular Malaysia to New Guinea. Three new synonyms are established, and H. aliceae sp.n. is described from Sarawak, Timor-Leste and Thailand. In contrast to recent treatments of Haplothrips, one of the most common members of the genus in Australia, H. angustus Hood is recognised as a syn.n. of H. ganglebaueri Schmutz that is widespread from Iran to Indonesia. Difficulties in distinguishing between three of the most common flower-living, Southeast Asian, species of this genus are discussed: H. anceps Hood from northern Australia, H. chinensis Priesner from Hong Kong, and H. brevitubus (Karny) from Japan.
Orthoptera from Sandakan, Sabah are relatively understudied compared to some other parts of Borneo, and lack of information of species there can impede our understanding of the origins and biodiversity of orthopterans in Borneo and, in general, Southeast Asia. Based on a recent orthopteran survey in Sandakan, one new species of Lebinthus Stål is described: Lebinthus sandakan sp. nov. The male calling song of this new species is also presented. The calling song of Cardiodactylus borneoe Robillard Gorochov, 2014 is also described for the first time.
The genus Carlschoenherria Bezděk, 2016 (Coleoptera: Scarabaeidae: Melolonthinae: Melolonthini) in the Philippines is reviewed. Three new species: Carlschoenherria adoradae Calcetas, new species, C. hadsallae Calcetas, new species, and C. gapudi Calcetas, new species are described, figured and compared with their close relatives. The following new combinations are proposed: Carlschoenherria palawana (Moser, 1915) new combination, C. philippinica (Brenske, 1894) new combination, C. argus (Burmeister, 1855) new combination, C. hastata (Arrow, 1938) new combination and C. vervex (Sharp, 1876) new combination. A new C. adoradae species-subgroup is proposed under the broader C. sulcipennis species-group. A key of the Carlschoenherria of the Philippines Islands, Malay Peninsula, Sumatra and Java is provided.
Seven new species of the genus Deltoplastis Meyrick are described: D. acutangulata Wang et Yu, sp. nov., D. anatoliana Wang et Park, sp. nov., D. multidentalis Wang et Yu, sp. nov. and D. similihoristis Wang et Yu, sp. nov. from China; D. aculeata Wang et Yu, sp. nov. and D. spatuliunca Wang et Yu, sp. nov. from Malaysian Borneo; and D. ovidiscalis Park et Wang, sp. nov. from Vietnam. Deltoplastis horistis (Meyrick, 1910) is newly recorded in China and its female is described for the first time. Images of adults and genitalia of the new species are provided.
The Barsine hypoprepioides (Walker, 1862) species-group is reviewed. Forty seven species and one subspecies belong to the species-group. Among them, fifteen species and one subspecies are new for science and described in the present paper: B. amoenissima sp. n. (Myanmar), B. selene sp. n. (Thailand and Laos), B. cao sp. n. (Thailand, Laos and Vietnam), B. speideli sp. n. (SE China, Thailand, Laos, Cambodia and Vietnam), B. mesomene sp. n. (NE India, Myanmar, China, Thailand, Laos and Vietnam), B. pandeia sp. n. (Vietnam), B. karenkensis wushipheri ssp. n. (S Taiwan), B. euryphaessa sp. n. (Vietnam), B. ivanovamariae sp. n. (Vietnam and SE China), B. eos sp. n. (Thailand), B. mene sp. n. (Thailand), B. syntypicoida sp. n. (Malaysia and Indonesia), B. dubatolovi sp. n. (The Philippines), B. visaya sp. n. (The Philippines), B. nemea sp. n. (The Philippines) and B. kishidai sp. n. (The Philippines). Eight new combinations are established: B. parameia (Rothschild, 1913), comb. n. B. takamukui (Matsumura, 1927), comb. n., B. karenkensis (Matsumura, 1930), comb. n., B. rhipiptera (Wileman West, 1928), comb. n., B. chi (Roepke, 1946), comb. nov., B. salakia (Schaus, 1922), comb. n., B. marginis (Fang, 1991), comb. nov. and B. dentata (Wileman, 1910), comb. nov. The lectotype is designated for Lithosia hypoprepioides Walker, 1862. Adults, male and female genitalia of all species are illustrated.
The island of Borneo lies within one of the most biodiverse regions in the world. Despite this, its documented gekkonid diversity is not commensurate with other areas of Southeast Asia. The megadiverse genus Cyrtodactylus is especially underrepresented. Limestone-karst ecosystems, in particular, harbor many endemic Cyrtodactylus species, but only one karst-dwelling species is currently recognized from Borneo. This paper adds two additional karst-dwelling Cyrtodactylus species-C. muluensis sp. nov. and C. limajalur sp. nov.-from Sarawak, Malaysia. Cyrtodactylus muluensis sp. nov. is endemic to Gunung Mulu and is distinguished from its congeners by having a precloacal groove, 31-38 ventral scales, a maximum SVL of at least 88 mm, enlarged subcaudals, 19-20 subdigital lamellae, and a banded dorsal body pattern. Cyrtodactylus limajalur sp. nov. is endemic to the Serian region and is distinguished from its congeners by having 33-42 ventral scales, enlarged subcaudals, a precloacal pit, a maximum SVL of at least 94 mm, 5-6 enlarged femoral scales, 19-22 subdigital lamellae, and five distinct bands on the dorsum. Both species are phylogenetically distinct and deeply divergent from all other congeners. The description of two new karst-dwelling species highlights the need to conserve karst habitats and the endemic species they harbor.
Two new species of the family Eriophyidae (Acari: Eriophyoidea) from Mount Trusmadi, Malaysia, are described and illustrated. They are Neodicrothrix grandcaputus sp. nov. on Stachyurus himalaicus (Stachyuraceae) and Latitudo asiaticis sp. nov. on Psychotria asiatica (Rubiaceae). Both of the two new species are vagrant on the lower leaf surface. No damage to the host was observed. In addition to the description, a key to species of Neodicrothrix is provided.
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.
