Remarks.

This tribe exhibits several primitive features (for example, mandibles with distinct mola) and belongs among the basal groups of Trogossitinae . While earlier entomologists always classified Acalanthis , Egolia and Calanthosoma together with Nemozoma and allied genera (for example, in the " Nemozomini " of Reitter 1876 and " Nemosomatinae " of Léveillé 1910), i.e. they always associated the present tribe with Trogossitinae , Crowson (1964a, 1966) was convinced of a relationship to Peltidae . His main reason was perhaps the relative primitiveness of adult egoliins with respect to trogossitids s.lat. Later, Crowson (1970) transferred it to Trogossitidae s.str., together with his newly-established subfamily Calitinae (in fact, only a change of status for Calityini Reitter, 1922). Having examined larvae of Egoliinae ( Acalanthis , Paracalanthis ) I consider its classification with modern trogossitins undeniable.
