''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. M

The beetles of this genus are diverse and the characters used to classify them are not well defined; historically, ''Acanthoscelides'' is a wastebasket taxon, "used as a genus into which species are placed that do not fit within the limits of other genera".
