Extremely resembles other species of this group in body shape and elytral pattern. Without dissecting male specimens could be rather difficult to distinguish. It differs from other species of the group by internal sac without spines, only with two, more or less cylindrical microtrichial patches composed of extremely small spicules. Description. Length 4.5–5.4 mm . Yellowish red-brown, elytra with black transverse band in middle ( Figs. 22– 24 ). Head with coarsel, deep and irregular punctation, dull, with very distinct microsculpture. Punctures separated by 1–1.5 their diameters, occasionally punctures spreading to zone between eyes. Eyes large and bulging. Pronotum 1.26–1.4 times as wide as head, 1.42–1.54 times as wide as long, widest behind marginal setae. Anterior margin straight, anterior angles effaced, sides regularly rounded, weakly sinuate before rectangular to weakly acutely prominent posterior angles. Punctation coarse, somewhat sparser on disc and sometimes confluent, especially at sides of disc. Lateral margin flat, rapidly widened basad lateral setae. Basal grooves indistinct, flat. Microsculpture strong and irregular. Elytra subovate to slightly elongate, 1.48–1.57 times as long as wide, with polygonal microsculpture. Striae deep, narrow and minutely punctate. Intervals 4–7 convex at humerus, gradually flattened towards apices; other intervals almost flat. Claws with 5 teeth. Abdominal smooth, shiny, with few short tiny setae. Propleuron, mes- and metepisterna smooth. Aedeagus ( Figs. 22–24 ). Aedeagal median lobe moderately broad, ventral surface almost straight to apex. Apex of median lobe moderately long, sometimes slightly downturned. Internal sac without spines, only with two, more or less cylindrical microtrichial patches composed of extremely small spicules. Size of spicules and shape of patches may slightly vary. Variation and comments. Throughout its large area of distribution varies in size, elytral pattern (dark transversal band may be reduced to spot on 1–4 intervals), shape of pronotum and aedeagal median lobe. The figures shows the extreme forms of variability ( Figs. 10–11 ). Most specimens shows intermediate forms. What unites them is only the general structure of internal sac of aedeagus. Perhaps S . (s.str.) africaorientalis sp. n. is a group of closely related species. The absence of complex internal structures of aedeagus does not allow divide it into species. To make a final decision about this taxon it is necessary additional material for make genetic analysis. Name derivation. The name refers to the area of distribution of this new species.
