Expected species richness in the genus psechrus in laos (Araneae: Psechridae)

Abstract

Three new Psechrus species are described from Laos, P. steinen sp. n., P. antraeus sp. n. and P. ancor ans sp. n. New records for P. luangprabang Jäger, 2007 are listed. Relationships of the three new species to other Psechrus species are discussed. Species with similar copulatory organs (P. singaporensis Thorell, 1894, P. rani Wang & Yin, 2001 ) are illustrated for comparison. P. rani is recorded for the first time from Vietnam.
