This paper gives the description of a new species of fish of the genus Acr- ossocheilus collected from mountain streamlets in the Wuyishan Natural Reserve of Fujian, China. Acrossocheilus (Lissochilichthys) wuyiensis Wu et Li, sp. nov. D. 4, 8; A. 3, 5; P. 1, 15-16; V. 1, 8; C. 19. Gill raker, 9-11. Pharyngeal teeth, 2. 3. 5. -5. 3. 2. Scales line, 40(5.5/(3.5-v))41. Predorsal, 13-14. Total length 60-159 mm., length 41-136 ram. Depth 3.30-4.14 in body length, head 3.47-4.46, depth of caudal peduncle 7.84-9.19, length of daudal peduncle 5.32-6.45. Snout 2.48-2.84 in head, eye 3.93-5.0, interorbital 2.63-3.26. Holotype: No. Ao174586, body length 159mm., collected from Huangxilikeng of Lijiatang Town, July 3,1980, preserved in the Laboratory of Animals of Fu- jian Agricultural College. Paratypes: 19 specimens, body length 41-91 mm., July 3-12, 1980, collected from Wuyishan Natural Reserve, preserved in the Laboratory of Animals of Fu- jian Agricultural College and Fujian Museum. This species can be distinguished from Acrossocheilus (Lissochilichthys) labia- tus (Regan) in having black blotches along the back, three before and one behind the dorsal fin; and in having longer maxillary barbel, which is 1.97 times as long as the eye. It resembles Acrossocheilus (Lissochilichthys) wenchowensis beijiangensis Wu et Lin in the pattern of black blotches and transverse bands, but differs from the latter in having no clear weak serrate on the last dorsal spine.
