摘要
In this paper three new species of genus Lordiphosa were reported from Yunnan,China.These three new species all belong to nigricolor species-group.All of the types were deposited in College of Life Sciences,Peking University. 1 Lordiphosa nigrifemur sp.nov.(Fig.1) Diagnosis:Femora dark brown to black except for terminal parts.Paramere (Fig.1:D,E) caudally bifurcated:dorsal branch approximately twice as long as ventral branch;anterior process small,ventral margin with ca.6 sensilla points medially.Aedeagus(Fig.1:D,E) double branched,bifurcated submedially at dorsal part of each branch,finger-shaped at the tips,dorsal process shorter;aedeagal basal process connected to gonopod with membrane,bearing numerous finger-shaped processes.Male Terminalia:Epandrium (Fig.1A) nearly entirely pubescent except for ventral and anterior margin,with ca.8 setae laterally and dorsally and ca.8 setae on caudoventral margin.Surstylus (Fig.1:A,B) with ca.12 dark brown,apically pointed primary prensisetae decreasing in size downward and arranging in convex row on nearly entire length of distal margin;with a few long stout spines on inner surface and 2 setulae caudoventrally.Cercus (Fig.1:A,C) oval,entirely pubescent,with ca.12 setae;tapering ventrally,with ca.5 stout spines in a row on caudoventral corner.Hypandrium(Fig.1:D,E) slightly triangular,without paramedian spines.Gonopods(Fig.1:D,E) fused,saddle-shaped in lateral view,with slender process at caudoventral margin.Apodeme(Fig.1:D,E) broad terminally,dark brown,approximately twice as long as aedeagus.Female Terminalia:Oviscapt (Fig.1F) apically round,submedially broad,with ca.13 marginal and ca.7 apically pointed lateral ovisensilla.Spermatheca (Fig.1G) oblate,with shallow indentation on capsule;spermathecal duct introverted into the inner tip of spermatheca.The basal half of introvert and duct both wrinkled. Holotype:♂,Deqin,Yunnan Province,China,alt.ca.3 650 m,8-Ⅵ-1994,coll.ZHANG Wen-Xia. Allotype:1♀,same data as holotype. Paratype:
