Abstract: | Homatula laxiclathra, new species, is here described from the Wei-He of the Yellow River drainage in Shaanxi Province, northern China. It is similar to H. berezowskii, H. longidorsalis, and H. variegata in the shared possession of a shallower body with a uniform depth, a character distinguishing all of them from all other congeners, but differs from these three species in the width of vertical brown bars on the caudal peduncle. This new species, along with H. berezowskii, differs from H. longidorsalis, and H. variegata in head length, caudal-peduncle depth, length of the dorsal adipose creast of the caudal peduncle, body squamation, and intestinal coiling. Homatula laxiclathra and H. berezowskii are further distinct in the caudal-fin shape and interorbital width. |
