Intertidal mudflat crabs of the genus Metaplax H. Milne Edwards, 1852 (Crustacea: Brachyura: Varunidae) from China, Taiwan, and northern Vietnam are taxonomically revised by morphological and molecular evidence. These crabs show sexual dimorphism and morphological variation of a considerable range in the infraorbital ridge, one of the primary features previously used for species identification. In this study, four species were identified from the region: M. elegans De Man, 1888; M. longipes Stimpson, 1858; M. sheni Gordon, 1930; and M. tredecim Tweedie, 1950. Based on the results of the morphological examination, and as confirmed by molecular evidence from mitochondrial cytochrome oxidase subunit I (COI), taxonomic confusion surrounding M. longipes was resolved, and M. takahasii Sakai, 1939, is considered a junior synonym of M. longipes. The geographical distribution of Metaplax longipes extends along the shores of China, north to Jiangsu, whereas the Southeast Asian M. tredecim was newly recorded from northern Vietnam and Hong Kong.

A New Species

Abstract This study dealt with three species of ornamental palaemonid freshwater prawns of the genus Macrobrachium, based on morphological and molecular analysis. Macrobrachium pentazona He, Gao & Guo, 2009; M. laevis Zheng, Chen & Guo, 2019; and M. bilineare sp. nov. are distinguishable from closely related species by segmental ratios, spination of the second pereiopods and the slender scaphocerite. Macrobrachium bilineare sp. nov. can easily be recognized in the field by its bright colour pattern. Molecular evidence of mitochondrial cytochrome oxidase subunit I (COI), also supports the characterization of this new species, raising the total number of Macrobrachium spp. known from China to 41. Detailed description, illustrations, colour photographs, habitat information, distribution maps and features of conservation significance are also briefly discussed.

Recently, Kehlmaier & Assmann (2008) presented a revision of the European representatives of the big-headed fly genus Chalarus Walker, 1834. The work introduced four previously unknown taxa and provided diagnoses of all other known species, illustrated through numerous line drawings and photo-micrographs. In total, the authors treated 25 species including one nomen dubium. Three of these were known from males only and five solely from females. Taxonomic decision-making was backed up by molecular evidence, published partly therein and in the context of a phylogenetic study of the subfamily Chalarinae (Kehlmaier & Assmann 2010). Despite large collecting efforts, three taxa could not be analysed genetically, namely C. argenteus Coe, 1966, C. elegantulus Jervis, 1992 and C. proprius Jervis, 1992, all representing species based on females only.    Shortly after the publication of the above mentioned revision, a specimen of C. elegantulus was identified amongst material sent by Dr. Gunilla Ståhls (Finnish Museum of Natural History, Helsinki): 1&, Finland, Ab (Regio aboënsis), Karjalohja, Karkalinniemi, 66581:33221, control trap #2, 25.VI.–22.VII.2007, leg. G. Ståhls, coll. C. Kehlmaier. The 5’ half of the mitochondrial cytochrome oxidase subunit 1 (CO1) gene was sequenced following standard lab procedures (see Kehlmaier & Assmann 2010) using the primer pair LCO1490 and HCO2198 (Folmer et al. 1994). The resulting DNA-barcode (Genbank sequence accession number: FN999909) was compared against a set of reference Chalarus barcode sequences and matched C. absconditus Kehlmaier in Kehlmaier & Assmann, 2008 syn. nov., a species know from male specimens only, sharing an identical haplotype.

A New Species

A new species of the megascolecid earthworm genus Pontodrilus Perrier, 1874, Pontodrilus longissimus sp. n., is described from seashores of Thailand and Peninsular Malaysia. The new species differs from congeners, especially the cosmopolitan P. litoralis (Grube, 1855) in the size of the body, number of segments and the shape of the spermathecae. P. litoralis is redescribed, based on specimens collected from the same region and the same type of habitat. DNA fragments of the mitochondrial cytochrome oxidase subunit I of both species were sequenced. Morphological as well as DNA sequence-based comparisons confirm that P. longissimus sp. n. is a lineage distinct from P. litoralis and in fact a new species. The illustrated descriptions are accompanied by a key to species of Pontodrilus.

A New Species

A new species of land-locked freshwater shrimp, Neocaridinafonticulatasp. n. (Atyidae), is described from Kenting, Hengchun Peninsula, Pingtung County, southern Taiwan. This new species can be distinguished from its congeners by rostrum structure, pereiopods, and male first and second pleopods. The molecular evidence of mitochondrial cytochrome oxidase subunit I (COI) also supports the establishment of a new species. This is the third endemic species of Neocaridina known from Taiwan.

Molecular Phylogenetic Data

The first stygobitic species of atyid freshwater shrimps from Vietnam is described from Cuc Phuong National Park, Northern Vietnam. Caridina thachlam sp. nov. can be distinguished from its congeners by a suite of morphological characters such as strongly reduced eyes without eyestalk, short and almost unarmed rostrum and slender pereiopods. Molecular phylogenetic data from the mitochondrial cytochrome oxidase subunit I (COI) and 16S ribosomal RNA genes also support the distinctiveness of the new species from all other species that we have examined.

A new freshwater crab is described from the montane area in northeastern Taiwan based on morphological and molecular evidence. Geothelphusa boreas sp. nov., from the Fushan Botanical Garden situated around New Taipei City and Yilan County, is distinct from similar congeners by the structure of the male first gonopod and the proportions of the male thoracic sternites. In addition, after comparing the holotypes of G. takuan and G. hirsuta Tan & Liu, 1998, no substantial difference could be found. Molecular evidence from mitochondrial cytochrome oxidase subunit I also supports the recognition of the new species and the conspecificity of G. hirsuta with G. takuan.

Epimeria schiaparelli sp. nov. from the Ross Sea, Antarctica, is described in detail. The new species occurs on the shelf in 130–350 m depth. Epimeria schiaparelli can be distinguished from the most similar species, E. similis Chevreux, 1912 and E. macrodonta Walker, 1906 by a relatively short rostrum and a short second pereonite amongst other characters. Two distinct colour patterns are reported. Partial gene sequences of the mitochondrial cytochrome oxidase subunit I (COI) from 11 specimens of E. schiaparelli confirm that this species is new to science and closely related to E. similis, E. macrodonta and E. reoproi. The recent and historical separation of this Antarctic species is discussed. The syntypes of E. macrodonta consist of two species, so a lectotype is here designated.

Sarcophaga Meigen, 1826 is proposed as a senior synonym of Cornexcisia Fan & Kano, 2000, syn. nov. and Fanzideia Xue, Verves & Du, 2011, syn. nov. Cornexcisia Fan & Kano, 2000, stat. rev. is given status as a subgenus and is considered a senior synonym of Fanzideia Xue, Verves & Du, 2011, syn. nov. at the subgeneric level. Cornexcisia is argued to contain S. (Cornexcisia) longicornuta (Fan & Kano, 2000), comb. nov., S. (C.) cygnocerca (Xue, Verves & Du, 2011), comb. nov., S. (C.) kurahashii (Shinonaga & Tumrasvin, 1979), subgen. comb. nov. (from Phallosphaera Rohdendorf) and S. (C.) suthep Pape & Bänziger, 2003, subgen. comb. nov. (from Rosellea Rohdendorf). Sarcophaga (C.) kurahashii is newly recorded from China (Yunnan), the male is redescribed and the female is described for the first time, supported by photographs, illustrations and mitochondrial cytochrome oxidase subunit I (COI) gene sequences. Species of Cornexcisia share an exceptionally long postpedicel in the female and the following apomorphic distiphallic appendages in the male: juxta ventro-proximally with an apically divided arm with cuticular pile, and lateral styli bifurcated from the base with each branch elongate, gently curved and slightly expanded apically. A key to the species of Cornexcisia is provided.
