| Popis: | A new genus and species of termitophilous staphylinid, SKATITOXENUS coatoni , is described from South- West Africa. This genus is so different from other staphylinids, both termitophilous and free-living, that a new tribe, Skatitoxenini, is proposed to contain it. It is the first termitophile to be reported from a new genus and species of termite related to Speculitermes . The species shows both positive and regressive glandular adaptations. Regressive adaptations are: reduction of the tergal defense gland and of the postpleural glands; type 1 glandular cells at the anterior edges of abdominal segments III–VI also somewhat reduced. Positive adaptations are: a stipital gland; type 1 glandular cells at the anterior edge of sternite VII and between tergite I and the metapimera; type 2 glandular cells numerous in all abdominal sclerites but especially in abdominal sternites and in the highly modified mouthparts. Glands associated with the genital organs were also studied. Some of the adaptations exhibit a convergent resemblance to those of the Corotocini, but these adaptations are sufficiently different in detail to support separate tribal status for the genus. |
