Background and Objective: The bean weevil, Acanthoscelides obtectus (Say) (Coleoptera: Bruchidae) is a serious Neotropical origin insect pest on kidney beans, Phaseolus vulgaris L. and other legume seeds. The objective of this study was to discriminate A. obtectus through morphological, molecular and biological studies. Materials and Methods: All stages of A. obtectus were morphologically described and their biology was performed. The adults of both A. obtectus and Callosobruchus chinensis were characterized by molecular analysis. Results: All the developmental stages were morphologically described. The morphological description of antennae, legs and wings of the adults indicated that the insect is A. obtectus. The partial sequence of COI gene of A. obtectus revealed 99% similarity with A. obtectus that previously recorded in GenBank and located in a separate glade in the phylogenetic tree. The biological parameters such as eggs per female, hatchability and durations of the developmental stages were also estimated. Conclusion: The morphological description, the partial sequence of COI gene and the biological parameters discriminated A. obtectus obviously from C. chinensis.
