Abstract 

Sinocyclocheilus simengensis Li,Wu,Li et Lan sp. nov. (Fig. 1).The upper side of the head is concave in the new species,with two protuberances,it similar with S. bicornutus (Xingren,Guizhou) and S. furcodorsalis (Tian'e,Guangxi),but the two protuberances of the new species are shorter,not triangular (Fig. 2).
Sinocyclocheilus pingshanensis Li,Li,Lan et Wu sp. nov. (Fig. 3).The new species is distinguished from all its congeners by the following characteristics:the morphological,distribution and last unbranched ray of dorsal fin with no serrations along the posterior edge,scale size along lateral line is similar with that of scales above and below lateral line. The new species is similar with S. macrolepis,S. guilinensis and S. jii,but it can be differentiated from S. macrolepis by last unbranched ray of dorsal fin hard (vs. soft),Scale row above lateral line 19~22 (vs. 11~14),Scale row below lateral line 11~13 (vs. 5~6);differentiated from S. guilinensis by last unbranched ray of dorsal fin hard (vs. soft),Scales along lateral line 75~78 (vs. 43~53),Scale row above lateral line 19~22 (vs. 19~20),Scale row below lateral line 11~13 (vs. 11~12);differentiated from S. jii by last unbranched ray of dorsal fin hard (vs. soft),Scales along lateral line 75~78 (vs. 47~52),Scale row above lateral line 19~22 (vs. 27~29),Scale row below lateral line 11~13 (vs. 15~17).
