Epierus lucus Lewis, 1884: 136 [Japan: Kasuga no Miya, Nara]; Bickhardt, 1917: 124; Mazur, 1984: 152.
Larger and more ovate than E. comptus; the head is very finely punctured, with a transverse stria between the eyes. The thorax is clearly punctate, and rather thickly so at the base in front of the scutellum; the interstices of the elytral striae are all finely punctured.
The type of this species came from a rotten tree in the ground of Kasuga
no Miya, at Nara, June 1881, and I believe all the species of this genus
are of arboreal halbits. I have only one specimen."
