Theopea Baly, 1864 species lacking a modified clypeus of East Asia are revised. Theopea aureoviridis Chûjô, 1935, T. collaris Kimoto, 1989, and T. sauteri Chûjô, 1935 are redescribed. Theopea coerulea Gressitt & Kimoto, 1963 is removed from synonymy with T. sauteri Chûjô, 1935. Hoplosaenidea irregularis (Takizawa 1978) and H. kanmiyai Kimoto, 1984 are transferred to Theopea and redescribed. A lectotype is designated for T. aureoviridis Chûjô, 1935. Five new species are described, T. cheni sp. nov. from Taiwan, T. geiseri sp. nov. from Northeast India, T. hainanensis sp. nov. from South China (Hainan Island), T. laosensis sp. nov. from West China, North Laos and Vietnam, and T. sekerkai sp. nov. from Central and South Laos.

Abstract The Stegana (Steganina) shirozui species group is mainly distributed in East Asia. In the present study, the molecular phylogeny of the S. shirozui group was investigated based on mitochondrial (COI and ND2) and nuclear (28S rRNA) markers. The resulting trees support the S. shirozui group as monophyletic and indicate that in this group, species associated with closer affinities show higher structural homogeneity in male genitalia. Molecular species delimitation assess most species limits and recognize four new species in the S. shirozui group from south-west China: S. alianya sp. nov., S. diodonta sp. nov., S. zebromyia sp. nov. and S. zopheria sp. nov. One new synonym was also recognized. Additionally, three typical male genital characters of the S. shirozui group were placed on the molecular phylogenetic framework. The outcome of both divergence-time estimation and ancestral area reconstruction suggests that the S. shirozui group likely originated in south-west China in the Middle Miocene.

Three New Species

Three new species of the genus Oligaphorura are described from southwestern China (O. wanglangensis sp. nov.) and Russian Far East (O. ussurica sp. nov. and O. kedroviensis sp. nov.). The first species is most similar to O. inya (Weiner & Kaprus’, 2014) known from the Altai Mountains, and can be distinguished from the latter by larger body size and the number of ventral psx (00/000/121101m in O. wanglangensis sp. nov. vs 1/000/212101m in O. inya). The other two species, together with O. montana Weiner, 1994, O. pseudomontana Sun & Wu, 2012 and O. chankaensis Sun & Wu, 2012, form a distinct species-group characterized by the presence of 4+4 pso on antennal base and full-sized anal spines. Both these new species differ from the known congeners of this group by having only 2+2 posterior pso on the head. O. ussurica sp. nov. and O. kedroviensis sp. nov. can be separated due to different number of abdominal pso, i.e. 5(6)5554 in the former vs 44454 in the latter species.

AbstractThe hispidus species group is formed for four new species from East Asia of the genus Plagiophorus Motschulsky: P. hispidussp. nov., P. hlavacisp. nov., P. serratussp. nov., and P. grandoculatussp. nov. Uncoated specimens were examined using field-emission scanning electron microscopy, and micrographs of the holotypes are presented. Keys to the species groups of the genus occurring in East Asia and to the species of the hispidus group are given. The hispidus group is probably monophyletic, having peculiar spinous setae on the male metasternum. The chaetotaxy of the labrum and clypeus is useful for distinguishing species of Plagiophorus.

A New Species

Sand bubbler crabs of the genus Scopimera are common on sandy shores in East Asia yet the taxonomy of the species remains unclear. Scopimera globosa De Haan, 1835, the type species, was described from Japanese specimens and also occurs in Korea and China. Scopimera tuberculata Stimpson, 1858, described from Japan, has been regarded a junior synonym of S. globosa, but the types had long been lost. Some workers have considered the two taxa distinct and S. tuberculata has been recorded from South China. In the present study, we confirm using male gonopod morphology and molecular analysis, that the early records of S. tuberculata from Hong Kong and S. globosa from Taiwan are in fact S. intermedia Balss, 1934. The present study regards S. tuberculata as a subjective junior synonym to S. globosa. A new species, Scopimera ryukyuensis sp. nov. from the Ryukyus, is identified and described herein. The new species is close to S. globosa but can be separated by carapace characters. The mitochondrial cytochrome oxidase I (COI) gene revealed basepair (bp) difference between the new species and other Scopimera spp. to be at the interspecific level, at least 28 bp (4.3%).

First Record

The fiddler crab fauna (Brachyura: Ocypodidae: Uca) of China is reviewed. Thirteen species are recognised here, viz. Uca acuta (Stimpson, 1858), U. annulipes (H. Milne Edwards, 1837), U. arcuata (De Haan, 1835), U. borealis Crane, 1975, U. coarctata (H. Milne Edwards, 1852), U. crassipes (Adams & White, 1848), U. dussumieri (H. Milne Edwards, 1852), U. lactea (De Haan, 1835), U. paradussumieri Bott, 1973, U. tetragonon (Herbst, 1790), U. triangularis (A. Milne-Edwards, 1873), U. typhoni Crane, 1975, and U. vocans (Linnaeus, 1758). Two females of U. typhoni collected from southern Hainan Island represent the first record of this species from China and East Asia. Two males of U. tetragonon collected from southern Hainan also represent a new record for China. The Uca fauna of southern Hainan is biogeographically distinct being different from those of northern Hainan and continental China, with U. annulipes, U. tetragonon, U. typhoni, and U. vocans common in Southeast Asia. In addition, continental China also lacks some insular species such as U. coarctata, U. formosensis Rathbun, 1921, U. jocelynae Shih, Naruse & Ng, 2010, U. perplexa (H. Milne Edwards, 1837), and U. tetragonon which are common in the East Asian islands of Taiwan and the Ryukyus.

The genus Typopeltis Pocock, 1894 is poorly known regarding its systematics, natural history, and distribution, despite important taxonomic advances during the 1990s. Currently, only 13 species are known from East Asia, including areas in south China, Japan, Vietnam, Laos, Thailand, and Taiwan. In this work, we describe and illustrate a new species of Typopeltis from Vietnam and provide a new description for the male of T.guangxiensis Haupt & Song, 1996. Additionally, we describe and illustrate the female gonopod of T.guangxiensis for the first time and propose a new homology hypothesis for the male gonopod parts. The male of T.laurentianussp. n. is characterized by the unique patellar apophysis that presents a smooth texture and no spines. Typopeltislaurentianussp. n. is the third species of this genus to be described from Vietnam.

A New Species

Specimens previously identified asBathyconchoecia paululasensu Yin & Chen, 1991 andBathyconchoecia galeritasensu Yin & Chen, 1991, together with two similar specimens, are reclassified as a new species,Bathyconchoecia incisasp. nov., which we describe and illustrate in detail here. The present species is similar toBathyconchoecia sagittariusandBathyconchoecia kornickeriin having a shallow notch on the posterodorsal corner of the carapace, but can be easily distinguished from these species by the structure of the posterior margin of the carapace and the striated sculpturing on the surface of the valves. The specimens on which this new classification was based were collected at shallow depths (<125 m) off the east coast of Hainan Island, in the northern South China Sea and in the Zengmu (James) Shoal and adjacent areas in the southern South China Sea.B. incisais likely to be a shallow-water species or has a wide bathymetric range.
