CLERUCHUS Enock, 1909

( Figs 94–101 )

Cleruchus Enock, 1909: 453 . Type species: Cleruchus pluteus Enock, 1909 , by monotypy. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Body dorsoventrally flattened ( Fig. 99 ); head strongly produced anteriorly, in lateral view almost triangular ( Fig. 95 ); ocelli, when present, far apart, with lateral ocellus next to posterior apex of supraorbital trabecula ( Fig. 94a ); female antenna with funicle segments about as long as wide and clava 1-segmented ( Fig. 97 ); fore wing narrow, parallel sided ( Fig. 96 ); ovipositor short, originating in apical third or less of gaster ( Figs 100b, 101b ).

Discussion. Cleruchus belongs to the Cleruchus group of genera. In the Afrotropical region this group also includes Cleruchoides , Eubroncus and Platystethynium . It is most similar to Cleruchoides ; in both genera the clava is 1-segmented and the fore wing venation is distinctly constricted anterior to the large triangular stigma ( Fig. 96 ).

Afrotropical hosts. Coleoptera .
