FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK XLII (XXXIV) 2 1981 p. 187-195 A revision of the Indo-Australian Gonolabis Burr, 1900 species (Dermaptera: Carcinophoridae) By H. STEINMANN (Received November 5, 1981) Abstract. - After a zoogeographical survey of the clrcumtropically 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 Indo-Australian faunal region. The description of three new species: Gonolabis bidens sp.n., G. gilesi sp.n., and G. dentata sp.n. is given. The systematical examination of the supraspecific taxa of the subfamily Carcinophorinae is a timely task. Several endeavours aiming to classify the genera of 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 Indo-Australian region are treated in detail. Gonolabis Burr, 1900 Gonolabis Burr. 1900, Ann.Soc.Ent.

Body of Euborellia- or Anisolabistype, but abdomen strongly expanded to last tergite. Head tumid, broad, postfrontal sutures and coronal suture distinct, very well or faintly visibly. Eyes relatively small, shorter than first antennái joint. Tegmina and wings completely absent, or tegmina rudimentary. Male forceps various, asymmetrical, and forceps of female almost symmetrical, tapering. Male genitalia well developed, genital lobes with or without virgae; external parameres longer than broad, outer margins usually sinuate. Species of genus distributed in the Aethiopical, Oriental and Indo-Australia regions. Identification key to the Indo-Australian species 1 (6) Genital lobes of male genitalia without virgae. 2 (3) External parameres of male genitalia expanded at middle portion, appendicular apex bifurcata (Fig. 2); genital lobes with very distinct reticulum lobi genitalis apically. Male forceps strongly asymmetrical, trigonal basally, and curved apically (Fig. 1) bidens sp.n.
