Systematics of the seed beetle genus Acanthoscelides (Bruchidae) of northern South America

A key to species, descriptions of species, synonymical names, and geographical distribution are presented for the 103 species of Acanthoscelides known to occur in Panama, Colombia, Ecuador, and Venezuela. Of the 103 species, the following 47 are described as new: akanthodes, aldanai, altocaura, ampl...

Description
Summary:A key to species, descriptions of species, synonymical names, and geographical distribution are presented for the 103 species of Acanthoscelides known to occur in Panama, Colombia, Ecuador, and Venezuela. Of the 103 species, the following 47 are described as new: akanthodes, aldanai, altocaura, amplilobus, aragua, barinas, bechyneorum, bogota, bolivar, buenaventura, canar, caripe, caroni, cesari, colombia, colombiano, coro, curimagua, darlingtoni, dominicana, donckieriopsis, elvalle, equivocada, falcon, fernandezi, guaibacoa, guanare, guarico, guiana, ingeborgae, jolyi, klagesi, machala, macheta, machiques, manleyi, maturin, monagas, ramirezi, santander, santarosa, sennicola, suramerica, tibiospinalis, tinalandia, yepezi, and zulia. Host plant records are reported for 72 of the species. Host associations are primarily with seeds of papilionoid Leguminosae. Seeds of mimosoid and caesalpinioid legumes also are fed upon as are seeds of the plant families Malvaceae, Sterculiaceae, and Tiliaceae. Although species of Acanthoscelides and most bruchids feed chiefly in seeds of the Leguminosae, based on ratios, about as many feed in the seeds of Malvaceae as feed in those of the Leguminosae. The legume genus Mimosa is the host most preferred by the species treated here because 37 species in the genus are fed upon by species of Acanthoscelides.
