Abstract

There are currently doubts about the correct genus of many Japanese species of coelotine spider provisionally classified in the genus Coelotes. Thus, taxonomic revisions were performed on 16 species with two retromarginal teeth on their chelicerae. Consequently, three new genera of the subfamily Coelotinae are described here. Aeolocoelotes gen. n. consists of seven species, which are characterized by extremely diverse variations in their genital organs and by the clear parapatric distributions among the congeneric species. Individuals in Aeolocoelotes gen. n. have large and dark-colored bodies, and females have a stiff chitinous epigyne. Curticoelotes gen. n. consists of six species, which are characterized by a short cymbium in the male palp. Finally, Griseidraconarius gen. n. consists of three species, which are characterized by their pale-colored bodies, spiraled conductors in the male palp, and tiny epigynal teeth.
