Acanthoscelides sousai Johnson, 1983  

This species is easy to recognize by its characteristic pattern of pubescence. In collections it is poorly represented, because it is difficult to collect. A reason may be high competition for host plants. In A. cornigera   , there is a complex of nine competing bruchid species. For example, in a sample of pods from this host collected at Campo Exp. Colegio de Postgraduados, km 21 carr. Cárdenas-Coatzacoalcos, Tabasco, Mexico, 23/X/2007, we found 33 specimens of A. oblongoguttatus   and only one specimen of A. sousai   . In its second host plant ( A. gentlei   ) there are two species of Mimosestes   ( M. brevicornis   and M. viduatus   ) also in competition with A. sousai   .

Host plants. OLD RECORDS: Acacia cornigera   (L.) Willd., Acacia gentlei Standley   , and Mimosa dormiens Humb. and Bonpl. ex Willd.
