Type localities.

The examination of the type of Alphitobius opacus  Gerstaecker, 1871 shows, that the original assignment to Alphitobius  is wrong and that this species must be transferred to the genus Peltoides  Laporte, 1832, subgenus Micropeltoides  Pic, 1916, because of entirely different body shape, different shape of antennomeres, and different shape of male genitalia with the base of basale not asymmetrical as in Alphitobiini  . The type of Peltoides (Micropeltoides) crypticoides  Pic, 1916 fully coincide with opacus, and is thus a junior synonym.
