Delobel) [CBAD]; other material as listed in Anton & Delobel (2003), including specimens from Burkina-Faso, Democratic Republic of Congo, Israel, Mauritania, Saudi Arabia and Sudan. A medium to large-sized (2.1–3.1 mm) species, from light yellowish to checkered with blackish and whitish spots; elytral intervals 1 and 2 blackened beyond half length, antennae and legs yellowish, apical antennal segments often darker; ventrite 1 with baso-central pear-shaped area with dense, semi-erect thinner setae in male; in female, last visible tergite with pair of oblong, micropunctate foveae that are devoid of shiny margin; Genitalia [see Figs. 1–7, p. 163 in Anton & Delobel 2003]. Internal sac slender (w/l = 0.12), entirely lined with small broad-based spines or slim based spines, and 19 to 44 large denticles with base twice as long as point; lateral lobes separated to about 80 % their length; tegminal strut with very small carina; in female, vagina long and membranous, with dorsal dentate sclerite. Biology. Reared from seeds of Dichrostachys cinerea (L.) Wight & Arn., Senegalia dudgeoni (Craib ex Holland) Kyal. & Boatwr., S. polyacantha campylacantha (Hochst. ex A. Rich.) Kyal. & Boatwr., S. macrostachya (Reichenb. ex DC.) Kyal. & Boatwr., Vachellia farnesiana (L.) Wight & Arn., V. gerrardii, V. nilotica adstringens (Schumach. & Thonn.) Kyal. & Boatwr., V. n. nilotica, V. n. tomentosa (Benth.) Kyal. & Boatwr., V. sieberiana (DC.) Kyal. Boatwr., V. tortilis and V. t. raddiana. Discussion. Bruchidius centromaculatus is morphologically related to B. arabicus and can be distinguished by having broader apical antennal segments, no or only shallow protuberances at base of elytra, apically broader male last visible tergite, paired foveae at apex of female last visible tergite, distinctly lower number of denticles in internal sac, dentate sclerites in bursa copulatrix [see Figs. 1 a–c in Decelle 1979 for habitus and male genitalia of B. arabicus]. Distribution. Burkina Faso, Democratic Republic of Congo, Egypt, Kenya, Mauritania, Saudi Arabia, Senegal, and Sudan.
