Genera of the Asian Catfish Families Sisoridae and Erethistidae (Teleostei: Siluriformes)

Abstract

External morphological traits diagnostic for valid genera in the Asian catfish families Sisoridae and Erethistidae were identified from publications and the examination of specimens. Diagnoses based on external morphological traits are predicted to significantly facilitate taxonomic revisions in these families. Erethistidae contains six valid genera (Ayarnangra, Caelatoglanis, Conta, Erethistes, Erethistoides, Pseudolaguvia) and about 25 species. Sisoridae contains 16 valid genera (Bagarius, Euchiloglanis, Exostoma, Gagata, Glaridoglanis, Glyptosternon, Glyptothorax, Gogangra, Myersglanis, Nangra, Oreoglanis, Parachiloglanis, Pareuchiloglanis, Pseudecheneis, Pseudexostoma, Sisor) and about 144 species. Lists of valid species and their distributions are given for each genus.

A new species of sisorid catfish genus Glyptothorax (Teleostei: Sisoridae) from Salween drainage of Yunnan, China

“…nov. from G. rugimentum and G. indicus, even though slightly overlapping. Such characteristics are reflected by the length of dorsal spine ( (Thomson and Page 2006), and it geographically separates from G. obliquimaculatus sp. nov.…”

“…Another species, Glyptothorax horai (Fowler 1934), is also distributed at Salween drainage in Myanmar (Thomson and Page 2006). There is no correlative record for this species in China.…”

“…Xie et al (2001) considered G. fukiensis as a synonym of G. sinense based on the method of morphometric principal components analysis. However, some ichthyologists believed that they should be distinct species (Thomson and Page 2006;Ferraris 2007). In addition, maybe because of the Chinese habit of pronunciation, a wrong spelling-fukiensis, existed in China for many years.…”

“…A description of the new species, Glyptothorax zhujiangensis, within the Southern Zhujiang River (Pearl River) added a new member to the Chinese Glyptothorax (Lin 2003). According to Thomson and Page (2006), there is a total of 21 species distributed in China, namely, G. annandalei, G. burmanicus, G. deqinensis, G. dorsalis, G. fokiensis, G. hainanensis, G. honghensis, G. interspinalum, G. lampris, G. laosensis, G. longicauda, G. longjiangensis, G. macromaculatus, G. minimaculatus, G. obscura, G. pallozonum, G. quadriocellatus, G. sinense, G. trilineatus, G. zanaensis and G. zhujiangensis.…”

New record of Glyptothorax brevipinnis (Hora, 1923) (Pisces, Siluriformes, Sisoridae) in the River Ken, Central India

“…Glyptothorax brevipinnis (Hora, 1923), considered a valid species (Burgess, 1989;Talwar and Jhingran, 1991;Ng, 2005;Jayaram, 2006;Thomson and Page, 2006;Ferraris, 2007), was also treated as a synonym of Glyptothorax pectinopterus McClelland, 1842 (Menon, 1999). The exact location where this species was first collected in India is not known but it was probably somewhere in the Ganga drainage.…”
