Alloblackburneusacutulus Bordat, 2009: 126 .

Typelocality. Matopos N. P. (20 o 33’S- 28 o 30’E), Zimbabwe.

Type repository. Zoologisches Museum, Humboldt Universität. Berlin (paratype examined).

Redescription. Length 2.5-3.5 mm; oblong, convex, moderately shiny, elytra very shortly pubescent. Reddish brown; epistome, pronotal disc, lateral margins of scutellum, elytral suture and sometimes also elytral disc, darkened; legs reddish brown with tarsi somewhat paler; antennal club pale testaceous. Headwith epistome gibbous, simply, rather denselyregularly andmoderately coarsely punctured; clypeus distinctly sinuate at middle, round at sides, thinly bordered, edge glabrous, somewhat reflexed anteriorly, lateral margins almost straight; genae obtusely round, glabrous, feebly protruding from the eyes; frontal suture finely impressed, not tuberculate; front evenly, almost coarsely, not closely punctured. Pronotum transverse, convex, simply, rather densely regularly andmoderately coarsely punctured; punctationsomewhat denser on sides; lateral margins subparallel toward the base, thinly bordered, edge glabrous; hind angles obliquely subtruncate; base feebly bisinuate, distinctly bordered, edge sometimes with few short hairs at scutellum level. Scutellum narrow with lateral margins arcuate, sparsely coarsely punctured. Elytra oval elongate, subdenticulate at shoulder; epiplerural carina shortly bristled toward shoulder; striae rather fine, feebly crenulate, wider toward apex; interstriae strongly convex, almost roof-shaped, finely serially punctured laterally; each puncture shortly recumbently pubescent. Hind tibiae superior apical spur shorter than first tarsal segment; latter as long as following three combined. Male: pronotum somewhat more transverse, less convex and somewhat more sparsely punctured; apical spur of foretibiae stouter and abruptly downward bent; metasternal plate distinctly excavate; aedeagus Fig. 4-5 . Female: pronotum somewhat narrowed anteriorly, somewhat more convex, and somewhat more densely punctured; apical spur of fore tibiae rather slender and moderately curved downward; metasternal plate almost flat.
