Koch M., Ďuriš Z., Huang J. & Chan T. 2014. First report of the swimming crab Ovalipes iridescens (Miers, 1886) (Brachyura, Portunidae) from Taiwan. Crustaceana 87(14): 1640-1647. DOI:10.1163/15685403-00003386
Abstract [+] [-]The portunid crab Ovalipes iridescens (Miers, 1886) is reported for the first time from the marine waters of Taiwan, and is just the second Ovalipes species known from this region. The only previously known Ovalipes species from Taiwan is a commercially-used species, Ovalipes punctatus (De Haan, 1833). The present study provides morphological and distributional data, and discusses the variability of the external morphology. The colour pattern of the body and the shape of the male gonopods of the newly recorded O. iridescens are illustrated.

Abstract [+] [-]A new species of portunid crab from the genus Cycloachelous Ward, 1942 is described from Vietnamese waters. Cycloachelous levigatus sp. nov. is morphologically most similar to C. orbitosinus (Rathbun, 1911), which was originally described from the syntype series collected from Western Pacific area (Cargados Carajos Islands, Amirante Islands, Seychelles) and C. octodentatus (Gordon, 1938) described from one single male from Singapore. There are differences in the sternal segments, third maxilliped, chela, abdomen and male gonopode shapes. The specific status of C. levigatus sp. nov. is also clearly supported by molecular data. Aside from a comparison of this new species with other known congeners, new photographs of syntypes of C. orbitosinus and the holotype of C. octodentatus are also provided.

Koch M., Spiridonov V.A. & ĎUriš Z. 2023. Revision of the generic system for the swimming crab subfamily Portuninae (Decapoda: Brachyura: Portunidae) based on molecular and morphological analyses. Zoological Journal of the Linnean Society 197(1): 127-175. DOI:10.1093/zoolinnean/zlac017
Abstract [+] [-]Abstract Swimming crabs of the genus Portunus are revised based on analysis of three genetic markers (COI, 16S and H3) and a morphological comparison. The analyses reveal the polyphyletic composition of Monomia, Portunus and Xiphonectes and the paraphyly of Achelous. Portunus, in our revised composition, is restricted to 13, Monomia to ten and Xiphonectes to 14 species. Other species are transferred to Achelous (28) and Cycloachelous (nine) or to newly established genera. Four new genera are separated from Xiphonectes and one new genus from Monomia. The systematic composition of the portunid subfamily Portuninae now comprises 11 genera: Arenaeus, Allomonomia gen. nov., Cavoportunus, Callinectes, Cycloachelous, Eodemus gen. nov., Incultus gen. nov., Monomia, Portunus, Trionectes gen. nov. and Xiphonectes. The genus Lupella is synonymized with Achelous (Achelouinae). Xiphonectes pulchricristatus and Xiphonectes spinipes are placed in Alionectes gen. nov., Portunus ponticus is transferred to Lupocycloporus (both Lupocyclinae), and Monomia euglypha is now placed in Cycloachelous (Portuninae). Portunus mokyevskyi is considered a junior synonym of Scylla tranquebarica (Necronectinae). Xiphonectes leptocheles is confirmed as a valid species. Cycloachelous granulatus unispinosus is also considered a valid species and is to be treated as Cycloachelous unispinosus.
