Anthaxia (Capanthaxia) capensis Kerremans, 1903 species-group

DEFINITION OF THE SPECIES- GROUP. Small to medium-sized (3.5–6.0 mm), black, black-bronze or multicolorous, asetose species ( Figs. 19–21 ).

Head relatively large, as wide as anterior pronotal margin, eyes large but not projecting beyond outline of head; antennae short reaching anterior third of lateral pronotal margins when laid alongside; sculpture consisting of very small, polygonal cells with tiny central grains.

Pronotum almost regularly convex, with fine, longitudinal, medial groove at least on posterior half ( Figs. 19– 21 , 52 ), lateral margins regularly rounded at anterior two thirds, posterior angles rectangular; lateroposterior depressions wide, very shallow sometimes almost missing; sculpture consisting of fine, transversely widened cells and transverse, somewhat undulate rugae on disc, and polygonal cells with central grains along lateral margins ( Fig. 52 ), exceptionally entire pronotum with fine, polygonal ocellation which is almost missing on disc ( Fig. 21 ). Scutellum small, subcordiform, only slightly longer than wide.

Elytra short, robust, widely, separately rounded apically, not completely covering the pygidium ( Figs. 19–21 ); lateral groove deep, in posterior half with large, strong punctures; humeral callosities small; basal transverse depression shallow, not reaching scutellum; sculpture consisting of rather fine, irregular punctures and strong punctures forming poorly defined, longitudinal rows ( Figs. 19–21 ); elytral epipleura wide, almost reaching elytral apex.

Anal ventrite of both sexes simply rounded, legs short, male metatibiae only with very fine, almost invisible, inner serrations.

Aedeagus ( Fig. 76 ) shortly spindle-shaped, parameres weakly narrowed at apical half, median lobe without lateral serrations.

DISTRIBUTION: South Africa (Cape Provinces).
