A review of the catfish genus Pterocryptis (Siluridae) in Vietnam, with the description of two new species

Abstract

Of the silurid catfish genus Pterocryptis in Vietnam, a total of four species are recognized as valid, of which Pterocryptis crenula and P. verecunda are described here as new. The type locality of P. cochinchinensis is restricted to central Vietnam, and the species is redescribed from topotypic material. Pterocryptis crenula (from northeastern Vietnam) can be differentiated from its congeners in having visibly confluent anal and caudal fins while P. verecunda (from Cat Ba Island in northeastern Vietnam) can be differentiated from its congeners in having the genital papilla concealed behind the anus. Notes on the identity of other nominal Pterocryptis species are also provided. 2001 The Fisheries Society of the British Isles

The complete mitochondrial genome of the catfish Silurus cochinchinensis (Siluriformes: Siluridae)

“…The mitochondrial genome of S. cochinchinensis was 16,501 bp in length and has been deposited in Genbank with accession number MH202954. The structural organization and gene order of the mtDNA was identical to other typical bony fishes, which contains the following: 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and one control region (Ng and Freyhof 2001 ; Xu et al. 2015 ).…”
