Abstract

We investigated the relative phylogenetic position of the spider genera Psechrus Thorell, 1878 and Fecenia Simon, 1887 comprising the family Psechridae Simon, 1890 within the order Araneae (plus 50 outgroup taxa) using molecular data of the nuclear 28S rRNA gene and the mitochondrial cytochrome c oxidase subunit I (COI) gene. We further revised the placement of genera formerly hypothesised in Psechridae and tested morphological species and species-group hypotheses recently proposed for Psechrus and Fecenia. Our results showed both genera as monophyletic and included within Lycosoidea but indicated no support for a monophyletic family Psechridae. Support for relationships to particular genera of other families (Lycosidae, Pisauridae) was found to be equally low. Previous removal of the genera Stiphidion Simon, 1902, Poaka Forster & Wilton, 1973, Tengella Dahl, 1901 (Metafecenia F. O. Pickard-Cambridge, 1902) and Themacrys Simon, 1906 from Psechridae is confirmed by recovering most of them outside Lycosoidea. For Tengella (part of Lycosoidea) a close relation to Psechridae is not supported. In the species-rich genus Psechrus, morphologically predefined species groups were generally recovered as monophyletic. COI information was applied to test the morphological species hypotheses for 28 Psechridae species, most of them represented by more than one specimen. Our analyses corroborated all proposed species and indicated COI as reliable for barcoding both Psechrus and Fecenia. COI enabled assignment of a juvenile specimen to Fecenia protensa, establishing the first species record for Brunei.
