Remarks. Type material of Paracladopelma simantodeea Sasa et al. was not examined. Paracladopelma simantodeea is a synonym of Paracladopelma furudoprimum on the basis of the description and figures of Sasa et al. (1998). The genus name Paracladopelma is neuter, and the adjectival ending of the species epithet is thus changed to ­um. The species is recorded from Russia for the first time.

Distribution. Palaearctic species. Known from Japan ( Sasa & Arakawa 1994) and the Russian Far East ( Makarchenko et al. 2005).
