Eidoreus is a genus of beetles in the family Eupsilobiidae, formerly placed in Endomychidae or Erotylidae. There are three described species in this genus.Deelder, C.L. (1942): Revision of the Erotylidae (Coleoptera) of the Leiden Museum. Zool. Meded. 24(3): 49-115. Fulltext

This genus resembles certain Erotylidae, such as Thaumastodacne, in overall appearance. A remarkable trait of these genera is that the mesosternum is so reduced as to be invisible, with prosternum and metasternum being directly adjacent.Deelder, C.L. (1942): Revision of the Erotylidae (Coleoptera) of the Leiden Museum. Zool. Meded. 24(3): 49-115. Fulltext
