Type species

Colpixys necator Waterston, 1916 , by monotypy and original designation.

Diagnosis

Pronotum with lateral semicircular ridge under protruding shoulders ( Fig. 2E ); face with V-shaped frontal suture; propodeum with coriaceous median furrow delimited by margins which are subparallel or weakly diverging posteriorly and more or less straight, submedian areas usually reticulate: lighter anteriorly and coarser posteriorly, lateral sulcus of propodeum incomplete ( Figs 1F , 8C , 9A–B , 11F ); prosternum evenly curved or at most with a carina ( C. eburnus sp. nov.); mesopectus poorly pubescent above mesofurcal pit; mesepisternum without epicnemial protrusion; axillula without a projection, at most with carinulae or plicae( Fig. 9C–D, F ); metascutellum long, semi-circular (but somewhat shorter in C. eburnus sp. nov.); supracoxal flange with setae; gena not bulging; male antenna with three-segmented funicle and two-segmented clava ( C. necator ) or five-segmented funicle (clava not present, C. gigas ); male gaster without pale subbasal spot.

Biology

The available records concern parasitism of larvae of Erotylidae and Languriidae ( Coleoptera ) ( Waterston 1916; Bouček 1972).

Distribution

Afrotropical region.
