To date, 20 species of Kurixalus Ye, Fei, and Dubois have been described, and all of these species are distributed throughout South and Southeast Asia, from eastern India, throughout Myanmar and the mountainous regions of southern China, to Indochina, western and northern peninsular Thailand, Malaysia, Sumatra, Borneo, and the Philippines (Frost 2021). Descriptions of the tadpoles of only 6 species have been published: K. berylliniris and K. wangi Wu, Huang, Tsai, Li, Jhang, Wu (Wu et al. 2016); K. eiffingeri (Boettger) (Kuramoto Wang 1987); K. idiootocus (Kuramoto Wang) (Kuramoto Wang 1987); K. cf. verrucosus (Boulenger) (Ziegler Vences 2002), and Kurixalus yangi Yu, Hui, Rao, Yang (Humtsoe et al. 2020). A description of the tadpoles of K. baliogaster (Inger, Orlov, Darevsky) is also given in the species description (Inger et al. 1999), but described larvae are assigned tentatively to this species in the published text. Additional studies on the identification of the conspecificity of the described tadpoles with K. baliogaster have not been conducted. Based on the much larger size of the tadpole body (TL up to 40.3 mm), as well as the labial tooth row formula 6(26)/5(1) given by Inger et al. (1999), we concluded that these described tadpoles cannot be larval K. baliogaster and most likely belong to some other species of rhacophorid frogs.
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).
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.
Two new species of thinly encrusting sponge Hamacantha (Demospongiae, Merliida, Hamacanthidae) are described from Japan. Hamacantha (Vomerula) mamoi sp. nov. was collected from Sagami Bay, and Hamacantha (Vomerula) umisachii sp. nov. from off Hachijo Island. This is the first record of Hamacantha and the Hamacanthidae from Japan. H. (V.) mamoi sp. nov. is characterized by having styles, two types of diancistras and one of sigmas. Only two known species have the same spicule composition: H. (V.) acerata Lévi, 1993 and H. (V.) esperioides Ridley Dendy, 1886, described from New Caledonia, and south-west Africa and south-east South America, respectively. H. (V.) acerata has larger diancistras and much smaller sigmas compared with those of H. (V.) mamoi sp. nov. H. (V.) esperioides can be separated by having larger styles and smaller sigmas than those of H. (V.) mamoi sp. nov. H. (V.) umisachii sp. nov is characterized by having styles, diancistras, cyrtancistra-like diancistras and sigmas. Hamacantha (V.) carteri Topsent, 1904 seems to have similar spicule composition, however the size of all spicule types is different.
The genus Lichnofugia is reported for the first time from India with a description of Lichnofugia umshingensis sp. nov. from Shillong, Meghalaya. The distribution of Lichnofugia thus extends eastward from Peninsular Malaysia and Thailand to north- eastern India.
The small pseudoscorpion family Pseudochiridiidae Chamberlin, 1923 comprises two genera and 12 extant species recorded from Asia (Burma, Christmas Island, Indonesia, India, Nepal, Malaysia, New Guinea, Philippines, Nicobars and Sumba), eastern, central and southern Africa (Chad, D.R. Congo, Kenya, South Africa, Tanzania), Madagascar, Seychelles (Aldabra), North America (Florida) and the Caribbean Islands of Dominican Republic and Cuba (Harvey 2013, Barba & Barroso 2013); one unidentified species is mentioned for the fauna of Mexico (Ceballos 2004). A fossil species has been described from Dominican amber by Judson (2007), who predicted the presence of this family in South America.
The monotypic genus Chandleriella Hlaváč, 2000 is reported from China for the first time, and a new species, C. yunnanica Yin, sp. nov. (type locality: Lincang, Yunnan), is described. It can be readily separated from C. termitophila (Bryant, 1915) of Sarawak by possessing a conspicuously modified antennomere 11 of the male.
The genus Eleazara Distant is reported from Malaysia for the first time based on one new species, E. viraktamathi sp. nov. This new species is described and illustrated. A checklist and key to the known species of Eleazara are provided.
Oliparisca menglaensis sp. nov. (Hemiptera: Fulgoromorpha: Cixiidae: Pentastirini) is described and illustrated from Yunnan Province of China. This represents the first record of the genus Oliparisca from China. The new taxon extends the distribution range of the genus Oliparisca, previously known only from Indonesia, Malaysia, Philippines and Sri Lanka. A key of identification to all known species of this genus and a map of their geographic distributions are provided.
Three new species of the fungal-inhabiting plant bug genus Punctifulvius Schmitz, 1978 (Cylapinae: Fulviini) are described, namely P. aleksanderi n. sp. from Selangor, Malaysia, P. parvus n. sp. from East Kalimantan, Indonesia, and P. sakaerat n. sp. from Nakhon Ratchasima, Thailand. The present discovery represents the first record of the genus from the Oriental Region. Punctifulvius members are now confirmed to be widespread from the cold temperate climatic zones in the eastern Palearctic regions, across the tropics of the Oriental Region, to the temperate rainforest of Australia. Punctifulvius kerzhneri Schmitz, 1978 is recorded from Taiwan for the first time. The systematic position of Teratofulvioides Carvalho & Lorenzato, 1978 is discussed, and its single species Teratofulvioides punctatus Carvalho & Lorenzato, 1978 is redescribed. Color adult habitus images of Punctifulvius aleksanderi, P. kerzhneri, P. parvus, P. sakaerat, and Teratofulvius punctatus, images of male (P. parvus and P. sakaerat) and female (P. aleksanderi) genitalic structures, as well as scanning electron micrographs of selected structures of P. aleksanderi, P. kerzhneri, P. parvus, P. sakaerat, and T. punctatus are provided. Key to the species of Punctifulvius is given.
The recently described genus Spinomarmessoidea is comprised of only 2 species from Peninsular Malaysia. The 3rd species of this genus, Spinomarmessoidea damingensis sp. nov. is described from Guangxi Province, China. The new species represents the first record of this genus in China. The granulose head of new species without large spines and mesonotum with short spines are distinguished from the other 2 species. A key to the female of this genus is compiled. Type materials are deposited in the Yunnan Agricultural University (YNAU).
The spider genus Desis Walckenaer, 1837 is the type genus of the spider family Desidae Pocock, 1895. Desis spiders hide in silk sacs between rocks or shells during high tide and forage during low tide (Baehr et al. 2017). Four Desis species have been recorded from Asia: Desis gardineri Pocock, 1904 (India), Desis inermis Gravely, 1927 (India), Desis japonica Yaginuma, 1956 (Japan) and Desis martensi L. Koch, 1872 (Malaysia) (World Spider Catalog 2020). Until now, only one species of the family Desidae, Badumna tangae Zhu, Zhang Yang, 2006, has been reported from China (Zhu et al. 2006). Here, we describe a new species of Desis and report the genus from China for the first time.
Five new species of the family Rotundabaloghiidae are described from Indonesia and Malaysia. Angulobaloghia pedunculata sp. nov. differs from the other Angulobaloghia Hirschmann, 1979 species in the shape of the genital shield of the female. Rotundabaloghia (Rotundabaloghia) wangi sp. nov. has one pair of short and pilose setae (V8) on the ventral idiosoma, which is unique in the subgenus Rotundabaloghia (Rotundabaloghia) Hirschmann, 1975. Rotundabaloghia (Circobaloghia) javaensis sp. nov. has a small triangular anterior process on genital shield of female, which has not been detected previously in South-East Asian members of this subgenus. The long and thick ventral seta (V4) in Depressorotunda (Depressorotunda) robusta sp. nov. is a character state so far unknown in the subgenus Depressorotunda (Depressorotunda) Kontschán, 2010. Depressorotunda (Depressorotunda) hirca sp. nov. has two apically serrate anterior branches on the margin of the female genital shield.
Six species in the genus Busonia Distant are described and illustrated, including five new species from Thailand and Malaysia: Busonia curvata, B. fusca, B. lactata, B. micrata, B. serrata, spp. nov., and one newly recorded species from China: Busonia albilateralis Maldonado-Capriles. A redescription of this genus is provided together with a key to species for separation of males.
An overview of the Oriental species of Cleruchus Enock (Hymenoptera: Mymaridae) is given, and its five newly described species as well as one undescribed species from Malaysia are keyed. The described new taxa are C. funiculatus Manickavasagam Palanivel sp. n., C. indicus Manickavasagam Palanivel sp. n. and C. orientalis Manickavasagam Palanivel sp. n., all from India, C. blimp Triapitsyn sp. n. from Brunei, and C. pmilb Triapitsyn sp. n. from Thailand. Anaphes quinquearticulatus Huber Triapitsyn is newly reported from India.
Five new species of Notosacantha are described from Borneo (Sabah): N. flaviventris Borowiec and Takizawa sp. nov. (also described from Sumatra), N. flavosuturata Świętojańska and Takizawa sp. nov., N. minuta Świętojańska and Takizawa sp. nov., N. obscuricornis Borowiec and Takizawa sp. nov. and N. ovoidea Borowiec and Świętojańska sp. nov.

Myrsinaceae and Myristicaceae are new host plant families for tortoise beetles and Ardisia elliptica Thunb., Ardisia sp., Embelia sp., Gironiema sp. (all Myrsinaceae) and Knema sp. (Myristicaceae) are new host plants for Notosacantha.
The genus Savarna Huber, 2005 comprises only five species, from southern Thailand, Peninsular Malaysia and Sumatra. In this study, five new species are described from Thailand: Savarna bannang sp. nov. (Yala), S. chiangmai sp. nov. (Chiangmai), S. huahin sp. nov. (Prachuap Kiri Khan), S. satun sp. nov. (Satun), S. thungsong sp. nov. (Nakhon Srithammarat). All new species are described from males and females. The distribution of S. chiangmai sp. nov. represent the northernmost record of the genus.
Megaselia bangiensis Disney sp. nov., M. cumpapillarum Disney sp. nov., M. hyplongiseta Disney sp. nov. and M. selangorensis Disney sp. nov. were collected from rabbit carcasses placed in concealed environments in Bangi, Malaysia.
The 'Cephennomicrus group' of Cephenniini includes nine genera distributed mostly in SE Asia (but with some species known also from other continents, except for the Americas). Four new Oriental species are described: Cephennococcus penangensis sp. n. (W Malaysia), Cephennomicrus matangensis sp. n. (E Malaysia), Cephennomicrus selangorensis sp. n. (E Malaysia), and Trurlia nova sp. n. (E Malaysia). Cephennomicrus selangorensis is unique in having the pronotum in both sexes with broad lateral impressions demarcated from the disc by a sharp ridge, a modification slightly similar to that of only one (Australian) congener.
