A medium to large-sized (2.6–4.7 mm) species, body light to dark brown, antennae and four anterior legs testaceous, often darkened, posterior legs reddish brown; pronotum with dense white setae on basal lobes and two lateral dots; elytra with white elongated spots separated by brown to black intervals in odd interstriae, even interstriae yellowish to largely dark brown; last visible tergite entirely white or with a median line of white setae, dark spots at base and middle, apex largely dark; female usually darker than male. Other distinctive morphological traits are as follows: antenna short, strongly serrate from segment 4 in male; base of interstria 4 bulging, with two wide teeth; first ventrite with small basal patch of erect setae; last visible tergite strongly turned under apically in male; in female antenna shorter, serrate from segment 5, last visible tergite regularly convex except faint bulge beyond middle, often almost bare, shining, without foveae.
Genitalia (Figs. 25–26): Median lobe elongated, almost cylindrical (maximum width excluding basal hood/ total length = 0.14), basal hood moderately widened; ventral valve large, subtriangular, with two lateral groups of 6 setae; no hinge sclerite; basal half of internal sac with 12–16 large thorn-like sclerites with broad base and blunt tip, followed by two median, hooked circular sclerites, then a pair of large thorn-like sclerites; posterior part of internal sac with a cluster of stout spicules; apical third with dense setation, ending in a setose tube; gonopore not sclerotized; basal strut narrow, with large keel; lateral lobes cleft to about 3/4 their length; apex straight, bearing about 18 short and long setae. In female, vagina long, entrance of bursa copulatrix with dorsal ovoid sclerite bearing a strong thorn-like spine oriented posteriorly, its surface lined with minute teeth.
Biology. Examined material was reared from the seeds of Vachellia nilotica (including V. n. tomentosa and V. n. adansonii) and Senegalia senegal. Also occasionally obtained from seeds of Vachellia flava, V. tortilis, and V. sieberiana in Mali and Senegal (Nongonierma 1978).
Discussion. As underlined beforehand B. uberatus is morphologically closely related to B. haladai.
Distribution. Angola (Decelle 1975), Burkina Faso (Nongonierma 1978), Egypt, Guinea (Zacher 1936), India (Allard 1895), Ivory Coast (Gillon et al. 1992), Mali, Mauritania (Nongonierma 1978), Namibia (Zacher 1936), Republic of South Africa (Van Tonder 1985), Senegal, Sudan (Fåhraeus 1839), and United Arab Emirates.
