Two new species of the subfamily Coelotinae (Araneae: Agelenidae) from Central Honshu, Japan

Abstract

Two new species of the genera Coelotes and Tegecoelotes, from Central Honshu, Japan, are described under the name of Coelotes isensisn. sp. and Tegecoelotes kumadain. sp. respectively. The former is included in the species group that has four retromarginal teeth on the chelicera, but there is no Japanese species that has a similar form of genital organs when compared to the new species. The latter can be distinguished from all congeneric species by its unique tegulum protruding downward in the male palp. In addition, male of T. kumadai is characterized by the leg formula of I–IV–II–III.
