A revised generic taxonomy for Far East Asian minnow Rhynchocypris and dace Pseudaspius

The Far East Asian dace and minnow clade Pseudaspininae of Leuciscidae sensu stricto, as recognized by molecular phylogeny, comprises three genera, viz. Oreoleuciscus , Rhynchocypris (removed from Phoxinus ), and Pseudaspius (including hitherto Tribolodon spp.). Descriptions of Rhynchocypris and Pseudaspius are revised following comparison with Oreoleuciscus as well as with two Eurasian genera Leuciscus and Phoxinus . Eurasian Leuciscus is distinguished from the other genera by having fewer than 60 longitudinal scales and Phoxinus by having a comb-like scale patch between the pectoral fin and opercle. Far East Asian Oreoleuciscus is unique in having a single pharyngeal teeth row, Rhynchocypris in having the anal fin base originating under the posterior end of the dorsal fin base, and Pseudaspius in having axillary scales on pelvic fin base.
