The present paper deals with a new genus and two new species belonging to the families Gnaphosidae and Corinnidae respectively.Specimens were collected by Miss Wu karyee from Hong Kong in 1995.The diagnoses of the new genus and species are given below.Types are deposited in the Department of Ecology,University of Hong Kong.All measurements given are in millimeters. Hongkongia gen nov. Cephalothorax ovate,with narrow front and a long median furrow.The anterior eye row slightly procurved,posterior eye row strongly procurved.AME and ALE contiguous.AME round and dark,but other six eyes oblique and angulate,white in color.PME nearer to laterals than to each other.Chelicerae with 3 promarginal teeth and a minute retromarginal tooth.Labium as long as wide,not extending beyond the middle of the endite.Cymbium of male palp narrow and long.Embolus and conductor long.Spinnerets long. Type species: Hongkongia wuae Song et Zhu Etymology:The generic name is derived from the type locality of the type species and is feminine in gender. Remarks:The new genus differs from the genus Megamyrmaekion Reuss,1834 in:1.Median eyes nearer to laterals than to each others;2.Promargin of chelicerae with 3 teeth other than 2 teeth,retro margin with a minute tooth other than unarmed;3.Labium as long as wide,not extending the middle of the endite;4.The anterior spinerrets not furnished with nine or ten large spinning tubes placed in a semicircle as in the latter. Hongkongia wuae gen et sp.nov.(fig.1) Holotype,Ho Pui (22°05′N,114°04′E),New Territory,August 21,1995,grassland,altitude 30m,pitfall trap,No.50. Length of male 5.56:cephalothorax 2.20 long,1.71 wide;abdomen 3.06 long,1.39 wide.Carapace ovate,light yellow brown.AME round in shape,dark in color.ALE,PME and PLE oblique and angulate,white in color.Abdomen:dorsum grey yellow with grey black fine spots,darder than carapece;venter light yellow orange in color. The specific name is a patronym in honor of the collector of the holotype,Miss Wu Karyee. Oedignatha platnicki sp.nov.(fig.2) Holotype,No.54,the same data as the species mentioned above. Length of male 5.32:cephalothorax 2.55 long,1.84 wide;abdomen 2.61 long,1.58 wide.Carapace sclero tized, red brown in color.Anterior eye row nearly straight.Posterior eye row slightly procurved.AME>ALE>PLE>PME.Promargin of chelicerae with 3 teeth,retromargin with six teeth.Labium longer than wide.Legs red brown.Tibia I:promargin of ventral surface with 8 spines,retromargin 7 spines.Metatarsus I with 6 pairs of ventral spines.Tibia II:promargin with 8 ventral spines,retromargin 6 spines.Metatarsus Ⅱwith 5 promarginal ventral spines,3 retromarginal ventral spines.Male palp:distal end with two processes,the dorsal one with 2 teeth.Embolus slender,located at the groove formed of conductor.Abdomen brown with irregular black spots.Whole dorsum and about 2/3 part of venter sclerotized. The new species may be readily distinguished from oedignatha mogamoga Marples by its chelicera and palp different. The specific name is a patronym in honor of Dr.N.I.Platnick of the American Museum of Natural History.
