The present paper deals with two new species of the family Philodromidae and their diagnoses are given below:Philodromus xinjiangensis sp. nov. (figs. 1-4)Holotype ♀, allotype ♂, paratype 1♀, Turpan County, Xinjiang Uygur Autonomous Region (42°55'N, 88°04'E), May 10, 1983, collected by Jia Guo-jun; paratypes 6♀♀ 1♂, Manas County, Xinjian (44°20'N, 86°20'E), June, 1981, collected by Yang Hai-feng. Type specimens are kept in the Institute of Zoology.Length of female 4.71 mm. Cephalothorax 1.86 mm long, 1.86 mm wide, ahdomen 2.00 mm long, 1.43 mm wide. Carapace orange on yellowish white background. Legs yellow or yellowish white with brown spots. Median septum of epigynum arched laterad. Spermathecae nearly round in outline.Length of male 3.71mm. Cephalothorax 1.86mm long, 1.66mm wide, abdomen 2.00 mm long, 1.43mm wide. Ventral apophysis of palpal tibia smaller and indistinct and set close to the retrolateral one.The r.ew species resembles Philodromus mysticus Dondale et Redner, 1975, but differs from the latter in the structures of epigynum and palp.Tibellus zhui sp. nov. (figs. 5-7)Holotype ♀, paratypes 21 ♀♀, Xichang, Sichuan Province (27°55'N, 102°20'E), October 16, 1975, collected by Zhu Chuan-dian. Type specimens are deposited in the Department of Biology, Norman Bethune University of Medical Sciences, Changchun, Jilin Province.Length of females 9.50-12.00 mm. Cephalothorax 3.40 mm long, 2.30 mm wide, abdomen 7.00 mm long, 2.00 mm wide. Carapace orange with brown spots, median longitudinal stripe brown. Eyes small, approximately uniform in size. Abdomen elongate, slender, with brown midstripe dorsad, and with one pair of small black spots near posterior end. Anterior half of epigynum concave, with copulatory openings at posterior margin. Spermathecae kidneyshaped.This new species may be readily distinguished from other members of the genus by its shape of epigynum.The specific name is a patronym in honor of Prof. Zhu Chuan-dian of Norman Eethune University of Medical Sciences, who made the type specimen available to us for study.
