The present paper reports a new species of Crossostoma collected from Zhejiang Province，China.Crossostoma galericula Zhang sp. nov.（Fig. 1）. Holotype: ZH070616, total length 54.1 mm, standard length 43.0 mm, collected in June, 2007 from a rivulet in Hehu Town, Qingyuan County, Zhejiang Province, China. Paratypes: 3 specimens, ZH070618（57.5 mm TL, 46.5 mm SL）, ZH070621（50.5 mm TL, 41.0 mm SL）and ZH070622（43.4 mm SL, 35.0 mm SL）. All paratypes have the same locality and same time as the holotype. D. III-8; A. II-5; P. I-13; V. Ii-8. Scales in L. l. 91-97. Depth of body in standard length 5.1-5.4, width of body 5.4-7.0, length of head 3.7-3.9, length of caudal peduncle 5.9-6.6, depth of caudal peduncle 7.2-8.8. Depth of head in head length 1.5-1.6, width of head 1.1-1.3, length of snout 1.8-2.1, diameter of eye 5.5-6.4, width of interorbital space 2.8-3.1. Depth of caudal peduncle in length of caudal peduncle 1.1-1.3. Width of mouth in width of head 2.2-2.5. Diagnosis: the new species has 13 sub-rostral barbells on the rostral fold. Bases of the rostral barbells are always connected to the rostral fold, and arranged in 1 row. This new species is similar to C. fasciolatus. But it can be distinguished from C. fasciolatus by the following comparisons: (1) the length of the longest rostral barbell is equal to the diameter of eye; (2) with 2 bright spots behind the sides of the dorsal fin; (3) all fins have no obvious spot; (4) naked area in abdomen extends to the base of the ventral fin.
