凹尾拟鲿(Pseudobagrus emarginatus)--长江上游中国鲇类一有效种(硬骨鱼纲:鲿科)
Pseudobagrus emarginatus (Regan, 1913), a valid Chinese bagrid species from the upper Yangtze River drainage (Teleostei:Bagridae)
摘要
Abstract
Pseudobagrus emarginatus is here regarded as a species distinct from P. pratti, and known only from the upper Yangtze River basin. It can be assigned to the species group comprising 18 species of Pseudobagrus characterized by having a smooth anterior margin of the pectoral-fin spine and short maxillary barbels not extending to the pectoral-fin insertion. It, along with P. ussuriensis, P. adiposalis, P. brevicaudatus, P. kyphus and P. pratti, differs from all congeners of the group in having a moderately forked caudal fin. Pseudobagrus emarginatus differs from P. ussuriensis and P. adiposalis in the number of vertebrae, dorsal-fin spine length, and P. brevicaudatus and P. kyphus in the structure of dorsal spine, and the presence or absence of the interspace between the supraoccipital process and the nuchal plate. It differs from P. pratti, in body depth, predorsal length, adipose-fin depth and caudal-peduncle depth. Both differ in many osteological characters related to the cranium, vomer, nuchal plate and pelvic girdle.关键词
