Abstract

Distoechodon species are widely distributed in rivers of southern China. Previous studies recognized only two species in the genus, viz., D. tumirostris and D. hupeinensis. A morphological analysis of 164 specimens from different localities permits recognition of four species. Distoechodon tumirostris is mainly restricted to small coastal rivers in the Zhejiang Province. Distoechodon multispinnis is widely distributed in the Chang Jiang and Zhu Jiang basins. Distoechodon compressus is known only from the Fujian and Jiangxi Provinces, and Taiwan. Distoechodon macrophthalmus, the new species, is known only from the Chenghai Lake, Chang Jiang basin in Yunnan Province.
