The female of Idastrandia orientalis (Szombathy 1915) is described for the first time, with redescription of the holotype male. Female specimens collected from the type locality share the somatic morphology of the holotype male, especially in the presence of a serrated retrolateral tooth on the chelicerae. On the basis of coloration and external morphological similarities, we conclude that our female specimens are conspecific with Idastrandia orientalis.
