A new species belonging to Sinocyclocheilus Fang, 1936 is describes in this paper. The new species was collected from Guangxi, China, and named as Sinocyclocheilus tianlinensis. Sinocyclocheilus tianlinensis sp. nov.(Fig 1) Description of holotype (in?mm). No. 20028, total length 117 and body length 93, collected from a cave in Ping Shan (24°50′N, 106°20′E), Tianlin County, Guangxi, China, Aug. 2000.

D. iii 8; P. i 11; V. i 7; A. iii 5. Depth of body in standard body length 3 4, length of head 3 0, length of caudal peduncle 6 6, depth of caudal peduncle 8 5. Length of snout in length of head 1 7. Depth of caudal peduncle in length of caudal peduncle 1 5. Body elongate. Snout projected, compressed and duckbill shaped. Back head hoiked and with non forked projecture forward. Without eyes. Mouth subinferior. 2 pairs of slender barbells. Without scales around body. Dorsal fin unbranched ray soft and without serration behind last unbranched fin ray.

The new species is similar to Sinocyclocheilus albeoguttatus (Zhou and Li, 1998), S. anatirostris (Lin and Luo, 1986), S. anophthalmus (Chen and Chu, 1988) and S. hyalinus (Chen et al ., 1994) in having degraded eyes, duckbill shaped snout, frontal projecture, translucence body, etc., but different from other known congeners in the genus (Zhang et al ., 2000). The new species is differented from S. albeoguttatus by its incomplete lateral line. The new species is differented from S. anatirostris and S. anophthalmus by its non forked frontal projecture, incomplete lateral line and without serration behind last unbranched dorsal fin ray. It is differented from S. hylianus by its less developed frontal projecture and last soft unbranched dorsal fin ray without serration (Fig 1). The new species was known to be distributed in underground water of a cave in Pingshan, Tianlin County, Guangxi, China.
