Abstract:The present paper deals with a new species in the genus Psechrus from China, named Psechrus triangulus sp. nov. This new species is closely related to Psechrus sinensis Berland & Berland, 1914, but differs from it with a triangular in epigynal median sclerite: the head of spermatheca protruding from inner surface of spermatheca, the tip of the embolus not pointed and the base of the embolus with two lamellar projections. The specific name is from the Latin triangulus, refering to the median sclerite of the epigynum triangular in shape. Type specimens are deposited in the Museum of Hebei University.
Keywords:Araneae  Psechridae  Psechrus  new species  China
