摘要
Two spined loaches, Cobitis oxycephala Chen YX ＆ Chen YF, sp. nov. and C. brachysoma Chen YX ＆ Chen YF, sp. nov., are described based on specimens collected from Guangdong and Hainan Provinces, South China. Morphology features and sequences of mitochondrial cytochrome b gene of these two new species were analyzed. Morphological and molecular data show that C. oxycephala Chen YX ＆ Chen YF, sp. nov. is closely related to C. dolichorhynchus Nichols, and C. brachysoma Chen YX ＆ Chen YF, sp. nov. is closely related to C. microcephala Chen ＆ Chen. These two new species can be distinguished from their congeners by the combination of characteristics of body shape, color pattern, lamina circularis, mental lobes, suborbital spine, subdorsal scales, and caudal peduncle.
