On the erigonine genera Hubertella Platnick, 1989 and Oia WunderHch, 1973 in the Himalayas (Aranei: Linyphiidae), with descriptions of two new species

摘要

The main somatic and genital diagnostic characters are summarized for the Himalayan genus Hubertella Platnick, 1989 and the Palaearctic East Asian genus Oia WunderHch, 1973. Two new species, Hubertella montana sp.n. and Oia kathmandu sp.n., are described from Nepal. Both species are most similar to their Himalayan congeners, i.e. H. thanku-rensis (WunderHch, 1983) and O. sororia WunderHch, 1973, respectively, but are clearly distinguished by the structural details of the genitalia. A new diagnostic drawing of the palpal structure is provided for H. thankurensis for comparative purposes, based on the holotype.
