摘　　要：旨在描述采集于云南省文山壮族苗族自治州丘北县树皮乡小新寨村龙山脚下一喀斯特洞穴出水口的金线鲃属鱼类一新种。新种以采集标本的地名命名为龙山金线鲃(Sinocyclocheilus longshanensis Li et Wu sp.nov.)。经形态学鉴定,该新种背鳍具有7根分枝鳍条,末根不分枝鳍条后缘呈锯齿状;眼正常;口亚上位;背部隆起;体侧分布有不规则黑褐色圆斑;侧线孔59~62。新种与背部隆起,体侧分布有不规则黑褐色圆斑,口端位、侧线孔81~88的麻花金线鲃(Sinocyclocheilus maculatus)能明显区分;与口亚上位,与背部无明显隆起,通体金黄色,侧线鳞71~81的阳宗金线鲃(Sinocyclocheilus yangzongensis)亦能明显区分。根据以上形态学特征组合,亦可将该新种与金线鲃属其他种明显区别。This study elaborates a new species in a karst cave near the foot of Longshan Mountain,XiaoxinzhaiVillage,Shupi Township,Qiubei County,Wenshan Zhuang and Miao Autonomous Prefecture,YunnanProvince,China.The new species is a member of Sinocyclocheilus,and named as Sinocyclocheilus longshanensis Li et Wu sp.nov.according to the name of collection region.Morphological observation showsthat the new species has 7 branched dorsal-fin rays,serrated trailing edges of the last unbranched dorsal-finray; normal eyes; sub-upper mouth,humped back; black-brown round spots distributed on exposed bodysurface; 59-62 lateral line pores.The new species can be distinguished from Sinocyclocheilus maculayus,which has humped back,black-brown round spots distributed on exposed body surface,and 81-88 lateral linepores.The new species can be distinguished from Sinocyclocheilus yangzongensis,which has flat back,goldenbody color,and 71-81 lateral line pores.The new species also can be distinguished from other species of Sinocyclocheilus by having the described combination of morphological characteristics.
