【Abstract】 The present paper reports the results of a systematic investigation of fishes Homalopteridae, based on a collection made by the writers in Fujian Province. The collection consists of 5 genera and 18 species, among which one species diagnosed as new to science. Pseudogastromyzon meihuashanensis,Li sp. nov. (Fig.1) D.3,7; A.2,5; P.1,17; V.1,9; L1.78～84; Body depth contained in standard length 5.2～6.2 (5.8),width of body 5.4～6.3(6.1), length of head 4.8～5.4(5.2),length of caudal peduncle 7.2～7.7(7.5),depth of caudal peduncle 9.1～9.8(9.5). Depth of head contained in its length1.7～2.0(1.8),width of head 0.7～0.9(0.8), length of snout 2.0～2.2(2.1), diameter of eye 4.0～4.3(4.2), width of interorbital space 1.4～1.7(1.6), length of coudal peduncle 1.2～1.8(1.6), its depth 1.7～2.1(2.0). Depth of caudal peduncle contained in its length 1.1～1.3(1.2),width of mouth contained in width of head 2.1～2.4(2.3). This new species is distinguished from any other known species of the same genus by its chin adhesive apparatus and the colour of its body. Its specific shape can be definitely identified by the following three respects: first, there are three dermal ridges extending fowards each corner of its under lip, but the three dermal ridges are slanting tightly, not like those of the other species: their three dermal ridges slanting separately and left a certain space between each dermal ridge. Second, in the center of the chin emerged a “π”,not like the other species (There are two “V”on P. liangiangensis and P. maculatus; two “Y” on P. fasciatus).And the shape of the adhering apparatus is not like the shape of "品" on P. changtingensis. Third, the colour on the body of the new species and the horizontal line on each side of the body differ from those of other known species. When alive, the whole body is showing the colour of orange and at the edge of its dorsal fin, there is a black line, and there are nine dark brown narrow indistinct horizontal lines of different lengths and irregular three black drops on each side of its body. Holotype No. FM00248, total length 83.0mm, standard length 68.0mm, collected in Jiulong River, Meihuashan Nature Reserve of Fujian Province(25°25′N,116°55′E), on November, 1990. Paratype No. FM01312. FM01313. FM01314, 3ex., total length 51.0mm～84.0mm, standard length 41.0mm～67.0mm, collected on January, 1977, same River as holotype. All type specimens are deposited at Department of Nature, Fujian Province Museum.更多还原
