  3. Garibian PG, Sanoamuang LO, Kotov AA
    Zootaxa, 2021 Oct 14;5052(2):111-129.

    It is widely accepted among the Cladocera (Crustacea) taxonomists that almost all cosmopolitan taxa are represented by some un-revised complexes of cryptic species. But many macro taxa of the cladocerans are still unrevised. The aim of this work is to analyze the taxonomic status of Oriental populations of the genus Bosminopsis Richard, 1895 (Anomopoda: Bosminidae) based on morphological characters. We have studied populations from India, Myanmar, Cambodia, Thailand, Laos, Vietnam, Philippines, Malaysia and Papua New Guinea and concluded that Oriental populations belong to a single species, Bosminopsis africanus (Daday, 1908), initially described from Africa. Analysis of literature data confirms that is widely distributed through whole Oriental zone. A single large mucro, or the mucro accompanied by an additional small spine in both sexes, is the main trait which differentiates B. africanus from B. zernowi Linko, 1901 distributed in more northern regions of Eurasia.

    Recent orthopteran surveys in the hyper-diverse Borneo, i.e., Brunei Darussalam and Sandakan in Sabah, allow us to review the scaly crickets from the subfamily Mogoplistinae there. We discover and describe the male, as well as formally naming Cycloptiloides bimaculata Tan, Japir Chung, sp. nov. from Sandakan. This species was previously described as sp. 1 in a comprehensive revision by Ingrisch (2006) but only the females were known. We also describe Ectatoderus nigrofasciatus Tan Wahab, sp. nov. from Brunei Darussalam. New locality records are reported for Apterornebius kinabalu Ingrisch, 2006 in Sandakan (Sabah) and Ornebius pullus Ingrisch, 2006 in Belait District (Brunei).

    A new saperdine species belonging to a new genus, Tsounkranaglenea hefferni gen. et sp. nov., is described from Sabah, Malaysia. The new genus differs from other genera of the tribe Saperdini by the special male sternite VII modified into a rake-shape, with the apex of the ventral plate of the median lobe unusually emarginated.

    The intertidal serpulid polychaete Spirobranchus kraussii was originally described from South Africa and has since been reported in numerous sub (tropical) localities around the world. Recently, however, S. kraussii was uncovered as a complex of morphologically similar and geographically restricted species, raising the need to revise S. cf. kraussii populations. We formally describe S. cf. kraussii from Singapore mangroves as Spirobranchus bakau sp. nov. based on morphological and molecular data. Despite their morphological similarities, Maximum Likelihood and Bayesian Inference analyses of 18S and Cyt b DNA sequence data confirm that S. bakau sp. nov. is genetically distinct from S. kraussii and other known species in the complex. Both analyses recovered S. bakau sp. nov. as part of a strongly supported clade (96% bootstrap, 1 posterior probability), comprising S. sinuspersicus, S. kraussii and S. cf. kraussii from Australia and Hawaii. Additionally, paratypes of S. kraussii var. manilensis, described from Manila Bay in the Philippines, were examined and elevated to the full species S. manilensis. Finally, we tested the hypothesis that fertilisation and embryonic development of S. bakau sp. nov. can occur under the wide range of salinities (19.630.9 psu) and temperatures (2531C) reported in the Johor Strait. Fertilisation success of ≥70% was achieved across a temperature range of 2532C and a salinity range of 2032 psu. Embryonic development, however, had a narrower salinity tolerance range of 2732 psu. Clarifying the taxonomic status of S. cf. kraussii populations reported from localities elsewhere in Singapore and Southeast Asia will be useful in establishing the geographical distribution of S. bakau sp. nov. and other members of the S. kraussii-complex.

    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.

    Taiwan is one of the richest in the world in terms of eel fauna. In this study, we examined the osteological and morphological characteristics of eels under order Anguilliformes. Furthermore, we focused on the neurocranium of total of 30 Anguilliformes fishes under family Congridae (10), Muraenesocidae (1), Muraenidae (7), Nemichthyidae (1), Nettastomatidae (2), Ophichthidae (5), Synaphobranchidae (4), which are caught in Taiwanese waters. This paper shows the results of a comparative study on osteological characters of the neurocranium including the ratio of seven length characters using its NCL (neurocranium length), NCW (neurocranium width), OBL (orbit length), MFW (maximum frontal width), NCDB (neurocranium depth at basisphenoid), PEVW (premaxilla-ethmovomer width) and mPOBL (mid pre-orbital length), and 20 morphological diagnostic characters for 30 eel species. Results shows that species under family Nemichthyidae and Nettastomatidae have the highest values on the ratio of NCL/MFW, NCL/NCDB, and NCW/mPOBD. In morphological characters, it shows that species of the same family mostly share similar formation of the PEV plate and frontal structure. The usage of the length measurements and morphological diagnostic characters of neurocranium allowed for a more in depth understanding of how similar or different these eels can be. The neurocranial description and morphological characters may prove valuable for identification purposes and might be necessary tool for further studies on the status of order Anguilliformes.

    Two new species of the gecarcinucid freshwater crab genus Arachnothelphusa are described from the Malaysian state of Sarawak in Borneo; one from Lanjak-Entimau Wildlife Sanctuary and another from Bako National Park. Arachnothelphusa rimba n. sp. is distinctive in possessing very long legs and a male first gonopod which has a cylindrical proximal part of the terminal segment, with the distal part sharply tapering to an acute tip. Arachnothelphusa bako n. sp. is superficially closest to A. kadamaiana from Sabah, but differs markedly by its narrower epistome, and proportionately shorter third maxillipeds and ambulatory legs.

    The species composition of the genus Epitettix (Tetrigidae: Cladonotinae) is discussed. The differential diagnosis of the genus is given. New synonymies are proposed: Epitettix Hancock, 1907 = Vaotettix Podgornaja, 1986, syn. nov., = Pseudepitettix Zheng, 1995, syn. nov. Two new taxa are described, namely Epitettix mikhailovi sp. nov. from Vietnam (Gia Lai Province) and Epitettix punctatus montanus subsp. nov. from Malaysia (Sabah, North Borneo). Seven new combinations are established: Epitettix guibeiensis (Zheng et Jiang, 1995), comb. nov., E. hainanensis (Deng, 2020), comb. nov., E. linaoshanensis (Liang et Jiang, 2004), comb. nov., E. nigritibis (Zheng et Jiang, 2000), comb. nov., E. pimkarnae (Storozhenko et Dawwrueng, 2014), comb. nov., E. strictivertex (Deng, 2020), comb. nov., and E. parallelus (Podgornaja, 1986), comb. nov. The unknown male of the latter species is also described and illustrated.

    The Rhoptrobothriidae are one of the more enigmatic families of cestodes of elasmobranchs. Opinions on the taxonomic status of the familys three original genera (i.e., Myzophyllobothrium, Rhoptrobothrium, and Myzocephalus) have varied over the 115 years since they were erected. Some authors have considered all three valid, others have considered Rhoptrobothrium to be a synonym of Myzopyllobothrium or a genus inquirendum, yet others have considered Myzocephalus to be a synonym of the phyllobothriid genus Thysanocephalum. All three genera were established for specimens collected from eagle rays off Sri Lanka. The erection of Mixophyllobothrium for two specimens from a cowtail stingray off India three decades ago added additional confusion to the situation, with some authors considering it valid and others a synonym of Myzocephalus. These disagreements stem largely from differences in interpretation of the complex morphology of the scolex of members of these genera. Furthermore, with the exception of Rhoptrobothrium comprising four species, each genus is monotypic. All but Rhoptrobothrium has not been considered in detail for nearly a century, largely because of a lack of available material. The taxonomic status of these genera is assessed here based on light and scanning electron microscopy, and molecular data generated from new material collected from eagle rays off Indonesian and Malaysian Borneo, Japan, Sri Lanka, and Viet Nam. Morphological work indicates that the genera differ largely only in the degree of folding of the four remi that extend from the cephalic peduncle. A molecular phylogeny based on sequence data for the D1D3 region of the 28S rRNA gene, which include new data for eight specimens of four species, indicates that Myzophyllobothrium, Myzocephalus, and Rhoptrobothrium are not mutually monophyletic. The latter two genera and Mixophyllobothrium are considered synonyms of Myzophyllobothrium and five species are transferred to that genus. Myzophyllobothrium okamuri n. comb. is considered a species inquirendum. Myzophyllobothrium nagasawai n. sp. is described from Aetobatus narutobiei off Japan. Myzophyllobothrium narinari n. comb. is re-described based on newly collected cestodes from the type host and locality (i.e., Aetobatus ocellatus off Sri Lanka). Despite consisting of only a single genus, the family status of the group is retained in recognition of the unusual configuration of the scolex, which bears four biloculate bothridia and four remi extending from the cephalic peduncle. The ordinal placement of the family remains uncertain, but affinities with the Phyllobothriidea, rather than Tetraphyllidea are considered.

    The agamid genus Bronchocela Kaup, 1827 comprises 13 species of diurnal, arboreal lizards distributed from India east through Myanmar, Thailand, Cambodia, Vietnam, Malaysia, Singapore, Indonesia, the Philippines, to Papua New Guinea (Diong Lim 1998; Hallermann 2005; Grismer et al. 2015). Once occupying this entire range, B. cristatella's distribution has now been restricted to the Andaman and Nicobar Islands, southern Thailand, Malaysia, Singapore, Indonesia, the Philippines, and Papua New Guinea (Hallermann 2005). My intention here is to: 1) clarify the type species of the genus-group name Bronchocela; 2) resolve the valid name for the taxon under consideration; 3) designate lectotypes for Agama cristatella Kuhl, 1820 and Agama gutturosa Merrem, 1820, and; 4) discuss the type locality for the taxon under consideration.

    Although the first issue of Zootaxa appeared in 2001 it was not until two years later, in August 2003, that this aspiring and inspiring new journal issued the first paper on the insect Order Thysanoptera, in Volume 268. Moreover, it was not until February 2005 that the second paper concerning this group appeared in Zootaxa. The subsequent expansion is summarized most succinctly by the number of Thysanoptera papers that appeared in Zootaxa in each of the four five-year periods of these two decades: 5; 40; 92; 134 (see Table 1). The 270 papers concerning this group of insects that appeared in Zootaxa over the 20-year period involved more than 120 authors. These papers were submitted by workers from about 30 different countries, but most of them were from areas of high but previously unexplored species diversity, particularly Australia, Brazil, China, India, Iran, Japan and Malaysia. However, significant contributions were submitted from the far north, including Poland and Russia, as well as the far south, such as Argentina and New Zealand. One reason for the popularity of Zootaxa amongst workers on thrips is presumably the knowledge that this section is edited by two active students of these insects. The editors are pleased to have rejected no more than five papers over these two decades, but they provide much help to authors in shaping manuscripts to ensure that the submitted information is both appropriate, scientifically correct, novel and clearly expressed. Moreover, the journal ensures that manuscripts are published very quickly, usually within four weeks of acceptance by the editors. For the readers a further advantage of Zootaxa is that just over 50% of the published articles on Thysanoptera are freely available on the web, as authors have arranged for Open Access. The thrips publications issued in Zootaxa have included descriptions of 563 new species and 41 new genera of Thysanoptera. These new species represent 9% of the 6300 valid extant species currently listed in this Order, and the new genera represent 5% of the 780 currently recognized genera (ThripsWiki 2021). Many of the publications are only of one or two pages and are issued as Correspondence. Each of these deals with a single new species, or a previously unknown male of a species, or some new and particularly unusual record for a country or host plant. At the opposite extreme are the Monographs that involve revisions of all of the species in a genus, such as the 60 species recognised in the South American genus Holopothrips, or the 30 species known in the worldwide genus Mycterothrips. Others provide illustrated keys to large numbers of genera, such as the 100 genera of Phlaeothripinae that have been recorded from South East Asia. Such extensive studies provide the factual resource on which many of the Articles published in Zootaxa are based. These Articles range from taxonomic revisions of small genera, or of the species found in particular geographic areas, through studies on character state variation and homologies, to historical accounts and catalogues. The very considerable increase in information in recent years about the taxonomic and biological diversity of this group of insects (Mound Hastenpflug-Vesmanis2021) owes much to the existence of the journal Zootaxa.
