Type localities.

“Ugano-Berge” (opacus), "Fort Crampel (Kaga Bandora)" (crypticoides).

Remarks.

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.

Distribution.

Tanzania (type locality opacus), Central African Republic (type locality of crypticoides); Senegal ( Ardoin 1963b), Ivory Coast ( Ardoin 1969), Mali, The Gambia ( Grimm 2002, all under Peltoides (Micropeltoides) crypticoides ); Benin, Cameroon, Guinea, Uganda, Angola, Zambia (new records).
