Other material as listed in Anton & Delobel (2003), including specimens from Algeria, Burkina- Faso, India, Jordan, Lybia, Mali, Niger, Oman, Sri Lanka, Sudan and Tunisia.

A small to medium-sized (1.4–2.7 mm) species, from light yellowish to checkered with blackish and whitish spots, elytra with double-toothed protuberance at base of striae 3–4, and a sharp isolated tooth at stria 2. Other distinctive morphological traits: in male, a large circular spot of short erect setae in basal angle of first ventrite; last visible tergite of female with pair of small foveae with shiny margin.

Genitalia [see Figs. 25–28 , p. 189 in Anton & Delobel 2003]: Internal sac entirely lined with small broad or slim based spines, and 3–6 large denticles with base as long as point; lateral lobes separated to about 80% their length; tegminal strut with very small carina. In female, vagina long, no dorsal sclerite at entrance of bursa copulatrix.

Biology. Reared from seeds of Vachellia farnesiana , V. flava , V. gerrardii negevensis (Zohary) Ragup. et al., V. hockii , V. nilotica tomentosa , V. seyal , V. tortilis , V. tortilis raddiana , and an unidentified species of Hydnocarpus (Achariaceae) . Dichrostachys cinerea , Senegalia senegal and V. sieberiana are other possible hosts.

Distribution. Algeria, Burkina Faso, Egypt, India, Iran, Israel, Jordan, Libya, Mali, Mauritania, Morocco, Niger, Oman, Saudi Arabia, Senegal , Sri Lanka, Sudan, Tunisia, United Arab Emirates, and Yemen ( Anton & Delobel 2003).

FIGURE 27. Results of molecular phylogenetic analyses. On the left side the best-fit maximum likelihood (ML) tree is figured. Support values are only provided for nodes leading to species (BV <50 % are not figured). On the right side the majority-rule consensus topology from Bayesian inference (BI) analyses is figured. Support values are only provided for nodes leading to species (PP <50 % are not figured). Representatives of the Bruchidius albosparsus species group are highlighted using a red frame.
