Popis: | Genus Centeterichneumon Heinrich, 1938 Centeterichneumon Heinrich, 1938: 129. Type species: Centeterichneumon denticoxatus Heinrich, 1938, by original designation and monotypy. Diagnosis According to Heinrich (1938: 22) the genus Centeterichneumon is characterized by having “ Clypéus largement arrondi. Spiracules du propodéum ovales chez les grands exemplaires, ronds chez les petits. Hanches III avec une petite dent chez la ♀ [= Clypeus broadly rounded. Propodeum spiracles oval in large specimens, round in small ones. Coxae III with a small tooth in ♀].” However, Heinrich’s (1938) diagnosis is insufficient to separate Centeterichneumon from the other Afrotropical genera. We hereby attempt a more in-depth diagnosis of the genus. Centeterichneumon can be distinguished from all the other genera by the following combination of characters: (1) bidentate mandibles (that sets Centeterichneumon apart from Lusius and Heterischnus); (2) presence of distinct gastrocoeli, even though superficial (that allows the separation from Arearia, Chauvinia, Dicaelotus, and Hoplophaeogenes); (3) non-modified hypostomal carina, meeting occipital carina at the base of mandible (modified in Aethecerus and meeting occipital carina above mandibular base in Tycherus); (4) 2 nd metasomal tergite roughly square (and not elongated as in Kibalus); (5) clypeus well-separated from face (epistomal sulcus present) (that allows a clear separation from Diadromus); (6) malar space less than 0.5× as long as the mandible (different from Diadromus); (7) hind coxae of female with a ventral tooth or small carina. Remarks The genus Centeterichneumon was introduced by Heinrich (1938: 129) to accommodate only one species from Madagascar, Centeterichneumon denticoxatus Heinrich, 1938, later divided into two subspecies, the nominotypical one and C. denticoxatus obscutatus Heinrich, 1938. Except for the original type series, no other records have been reported for the genus. Townes & Townes (1973) provided a catalogue to the species with no new information on the distribution, while Rousse et al. (2013) failed to include the taxon into their review of the Afrotropical Phaeogenini. The species hereby newly described represents the first record of the genus after its original conception and expands its distribution for the first time to mainland Africa (Figs 5A–B, 8A–B).
