【Abstract】 During the years of 1973 to 1976, several collections of fishes were made in the region of Qinghai-Xizang plateau. Seven genera and ten species of the family Sisoridae were identified and they are listed as follows.1. Glyptothorax zanaensis, sp. nov.2. Glyptothorax annandalei Hora3. Pseudecheneis sulcatus (McClelland)4. Glyptosternum maculatum (Regan)5. Glaridoglanis andersonii (Day)6. Parachiloglanis hodgarti (Hora), gen. nov.7. Euchiloglanis kamengensis Jayaram8. Euchiloglanis gongshanensis Chu9. Euchiloglanis gracilicaudata Wu et Chen 10. Exostoma labiatum (McClelland)In the present list one can easily recognize the two new forms; one is a new genus and another is a new species. These new forms are diagnosed as follows.Parachiloglanis, gen. nov.,The new genus is described basing upon the type species--Glyptosternumhodgarti Hora, 1923. It is characterized by having no postlabial groove, thus the lower lip continuing with the isthmus without demarcation, and by the presence of arch-shaped teeth band in the upper jaw; the former characteristic differs from all the glyptosternoid genera of which the postlabial groove is always present and the latter characteristic is only known previously in two genera, Glyptosternum and Coraglanis of the glyptosternoid fishes.Glyptothorax zanaensis, sp. nov.The new species is closely related to Glyptothorax gracilis (Gunther) but differ from the latter in the following characteristics: (1) skin with scanty dermal papillae, especially posterior part of the body; (2) occipital process not contact with the basal bone of the dorsal fin; (3) the dorsal fin situated ahead, the distance from its origin to end of the snout is comparatively shorter than the distance to the origin of adipose fin; (4) the dorsal spine weak, enveloped with skin, its posterior serration feeble; (5) the origin of pelvic fin is distinctly behind the posterior end of the base of the dorsal.更多还原
