Two new species of glyptosternine catfish of the genus <i>Sineuchiloglanis</i> (Teleostei, Siluriformes, Sisoridae) from the upper Yangtze River drainage, China.

ABSTRACT: Two new species of the genus Sineuchiloglanis are described from two tributaries of the upper Yangtze River, China. These two new species can be distinguished from all congeners by morphological comparisons and phylogenetic analysis. Sineuchiloglanis chishuiensis sp. nov. can be distinguished from its congeners by the combination of the following characters: eye enlarged, with diameter 6.8-9.1% of head length (HL); interorbital width 24.1-24.8% of HL; maxillary barbel length 67.1-84.4% of HL; caudal-peduncle depth 27.1-40.3% of caudal-peduncle length; dorsal-fin rays i, 5^1/2; anal-fin rays i, 4^1/2; caudal-fin rays i, 7+8, i; gill opening extending to the base of second to third pectoral-fin elements; tip of nasal barbel not reaching anterior orbit
