A revision of the genus Epiphanis Eschscholtz, 1829 (Coleoptera: Eucnemidae: Melasinae: Epiphanini)

Abstract

The cosmopolitan false click beetle genus, Epiphanis Eschscholtz (Coleoptera: Eucnemidae: Melasinae: Epiphanini) distributed largely across the Holarctic region is revised. Eleven new species are described: Epiphanis ainu (type locality: Shikoku, Japan), Epiphanis apache (Arizona, USA), Epiphanis basque (Spain) Epiphanis dobunni (England, British Isles, UK), Epiphanis hoh (Washington, USA), Epiphanis kwakiutl (British Columbia, Canada), Epiphanis menominee (Wisconsin, USA), Epiphanis navajo (New Mexico, USA), Epiphanis shoshone (Idaho, USA), Epiphanis ute (Utah, USA) and Epiphanis yayoi (Hokkaido, Japan). Epiphanis cristatus LeConte status restored and Prosopotropis devillei Abeille de Perrin are resurrected from synonymy with Epiphanis cornutus Eschscholtz. Furthermore, Fleutiaux (1920) had concluded that Prosopotropis devillei and Epiphanis cornutus are conspecific. After interpreting contents of the information provided by Abeille de Perrin (1898) and Fleutiaux (1920) and comparing the descriptions against the holotype of E. cornutus, it is concluded Abeille de Perrin’s species belongs to Epiphanis resulting in a new combination: Epiphanis devillei (Abeille de Perrin) from which the species is quite different from that of E. cornutus. Epiphanis cornutus, Epiphanis cristatus, Epiphanis devillei and Epiphanis tristis (Sharp) are redescribed. Holotype images for E. cornutus collected from Baranof Island near Sitka, Alaska from the Zoological Museum in Moscow (ZMUM) are included. A checklist for all species of Epiphanis present in the Holarctic region is provided. Each species in this study is diagnosed and illustrated. An identification key is provided for all known species of Epiphanis.
