description: Key to the Alevonota species of the Western Palaearctic region
The following key does not account for A. lentipes (PEYERIMHOFF, 1938), a doubtful species originally described from Algeria, but also recorded from Morocco (SMETANA 2004). According to the original description, it is similar to A. rufotestacea, but distinguished by more transverse antennomeres VI-X, coarser puncturation of the pronotum, and darker coloration.The details indicated in the description do not rule out the possibility that the species is in fact conspecific with A. rufotestacea.
