Large species well defined by its mainly red colour, with major part of antennae, elytra, and often disc of mesothoracic sternite, black ( Fig. 1 ); pubescence white, denser on median longitudinal line of pronotum, scutellum, base of elytral suture; pygidium with two lateral spots near base and a longitudinal line. Other major morphological traits are as follows: pronotum 1.5 times wider at base than long, without oblique lateral impression, its sides concave, produced anteriorly into a neck; elytral striae narrow and deep, with small punctures, interstriae wide and flat, with small punctures on shagreened background; antennae serrate. Male genitalia. Median lobe ( Fig. 8 ) of moderate length (maximum width excluding basal hood / total length = 0.23), strongly widened and sclerotized apically; basal hood oval, apically indented; ventral valve large, subtriangular, with apex acute, with numerous sensillae, bearing two lateral groups of 10–12 setae; dorsal valve unsclerotized; no hinge sclerites; anterior part of the internal sac lined with hyaline spinules becoming denser and larger distally, then large ctenoid scales, posterior saccus with numerous sclerotized teeth; apical ampoule unarmed. Tegminal strut ( Fig. 9 ) without keel, triangularly pointed apically, lateral lobes cleft to base; apex of parameres with numerous setae, slightly modified, with dorsal velum. Biology. Specimens from Thange were reared from a sample of Crotalaria sp. near polysperma pods. This constitutes the first report on its biology. Distribution. Kenya and Zimbabwe . Discussion. The red color of the last visible tergite distinguishes Conicobruchus rubricollis from C. cicatricosus , C. flabellicornis and C. strangulatus ( Fig. 1 ). It cannot be confounded with C. decoratus based on differences on the shape of the pronotum. Finally the presence of a longitudinal line of whitish setae on the pronotum separates C. rubricollis from dark specimens of C. atrosuturalis . Male genitalia ( Fig. 8 ) are similar in shape with other members of the group (except C. decoratus ) but completely lack large sclerites.
