Two newly recorded species of the family Gnaphosidae (Araneae) from Japan

Abstract

Two gnaphosid species, Heser infumatus (O. Pickard-Cambridge 1872) and Hongkongia reptrix Deeleman-Reinhold 2001, are reported as new records from Japan. The genera Heser Tuneva 2004 and Hongkongia Song & Zhu 1998 are recorded from Japan for the first time. Heser infumatus is distinguished from the other Japanese species of the subfamily Zelotinae by the epigyne with a pair of transvers furrows (copulatory openings) in median part. Hongkongia reptrix is separated from the other Japanese gnaphosids by having the posterior eyes closely situated to one another, the posterior eye row distinctly procurved, and the long spinnerets.
