FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK (SERIES NOVA) XXXI. 1. 1978 p. 189-197 A revision of the African Gonolabis Burr, 1900, species (Dermaptera: Carcinophoridae) By H. STEINMANN (Received November 16, 1977) Abstract: After a zoogeographical survey of the circumtropically distributed species of the genus Gonolabis Burr, 1900 was it possible to revise systematically this particular group. The present contribution summarized the findings of a comparative morphological study of the male genital apparatus of the species inhabiting the Ethiopie faunal region. The description of two new species: Gonolabis splendida sp. nov. and G. puella sp. nov. is given. The systematical examination of the supraspecific taxa of the subfamily Carcinophorinae is a timely task. Several endeavours aiming to classify the genera or species-groups of this subfamily were published. All these conclude to the nowadays generally accepted view that only the comparative morphological and microsystematical study of the male genital apparatus give reliable results. The old descriptions based on external morphology may be evaluated on the basis of a systematical revision covering the entire family. At this place the representatives of the genus Gonolabis inhabiting the Ethiopie region are treated in detail. Gonolabis Burr Gonolabis Burr, 1900, Ann. Soc. Ent.

Discussion: General colour dark brown to reddish brown or yellowish brown, rarely black. Body Euborellia- or Anisolabistype, but abdomen expanded to ultimate tergite. Head tumid, postfrontal sutures and coronal suture distinct, very well or faintly visible. Eyes relatively small, shorter than scape. Tegmina and wings absent, or rudimentary. Forceps of male asymmetrical, rarely symmetrical, female's forceps contiguous, tapering. Male genitalia various, external parameres longer than broad, pointed or obtuse apically; genital lobes well developed, with or without virgae. Distribution: Africa, Indo-Australia, and Oriental region.
