Acanthoscelides Oblongoguttatus
''Acanthoscelides'' is a genus of bean weevils of the subfamily Bruchinae. They are native to the New World. About one third of them can be found in Mexico.Nápoles, J. R. and J. M. Kingsolver. (2009)A new species of ''Acanthoscelides'' Schilsky (Coleoptera: Bruchidae) from Mexico with some biological notes.''Neotropical Entomology'' 38(4), 497-500. In 1946 this genus was populated with at least 322 species transferred from other genera, mainly ''Bruchus''. Some of these were later placed into other genera.Kingsolver, J.

Acanthoscelides Obtectus
''Acanthoscelides obtectus'', the bean weevil, is a species of bruchid beetle. The species was described in 1831 by Thomas Say. Bean weevils feed primarily on the seeds of common beans but also feed on the seeds of peas, vetches, and many other leguminous plants. They have also been reported to develop on the seeds of a few non-legumes, such as maize and buckwheat. Bean weevils are pests of legume seeds both in field and in storage. Only the larvae feed on seeds: the adults feed on pollen. Originating in mountainous regions of northern South America, its has been inadvertently introduced to Central America, then around the world in grain shipments. Taxonomy American naturalist Thomas Say described the bean weevil species as ''Bruchus obtectus'' in 1831, and was later moved to the genus ''Acanthoscelides''. In a 1870 publication John Lawrence LeConte mistakenly called it '' Bruchus obsoletus'', which led several later author to call it under this name which in fact belong ...
