A medium-sized (2.1–3.0 mm) species with yellowish to reddish brown integument and various darker areas, antennae and 4 anterior legs light testaceous, posterior legs slightly darker. Vestiture generally pale, with more or less extended brown patches: pronotum mostly brown, with median longitudinal line and basal lobes, white or yellowish; usually elytra with three irregular transversal rows of dots and apex, often more or less extended circular or rhomboid sutural spot, brown; last visible tergite light coloured, with base and median line more densely setose, and often a brown elongated spot on each side. Other major morphological traits are as follows: two minute teeth at base of striae 3 and 4; last visible tergite of female moderately bulging in apical one-third, without foveae; base of ventrite 1 of male with large patch of short yellowish erect setae.
Genitalia (Figs. 3–4): median lobe short, stout (w/l = 0.20), apically widened, dorsal valve braced by strongly sclerotized ring, ventral valve acutely subtriangular, with two groups of 5 setae, internal sac lined with transparent tubercles, in proximal part a short dentate sclerite that lays in dorsal position when evaginated, followed by a long sclerite composed of 15–20 fused teeth, and a pair of short lateral teeth; apically a pair of leaf-like, lightly sclerotized plates. Tegminal strut with large carina, parameres short and apically truncated, cleft to 63% their length and with about 10 setae.
Biology. Reared from seeds of Vachellia tortilis, V. t. raddiana and V. t. spirocarpa.
Discussion. Bruchidius senegalensis was a replacement name for B. mimus Gyllenhal from Senegal. Subsequently the name senegalensis was erroneously used by authors for several other species (B. centromaculatus, B. cretaceus and B. meridionalis); the identity of B. senegalensis was established by Anton & Delobel (2003).
Distribution. Algeria (de Luca 1962), Burkina Faso (Nongonierma 1978), Chad (Hoffman 1965), Kenya, Mali (Nongonierma 1978), Mauritania (Nongonierma 1978), Morocco (de Peyerimhoff 1926), Saudi Arabia (Anton pers. com.), Senegal, Tunisia, and Yemen (Anton pers. com.).
