Notes on Bruchidae of America North of Mexico With a List of World Genera

Abstract

This paper contains notes affecting the classification of the Bruchidae of United States and Canada, a list of all species found north of Mexico, and a list of World genera and their type-species. The Mexican Merobruchus vacillator (Sharp) is added to the fauna of this area. Transferred from our list to that of Latin America are: Acanthoscelides californicus (Boheman), Megacerus eugenie new name for Bruchus ramicornis Boheman nee Erichson, and Mimosestes innotatus (Pic.). The following are synonymized: Spermophagus (Zabrotes) semicinctus Horn (1894) with Zabrotes subfasciatus (Boheman 1833); Bruchus subserripes Fall (1910) with Acanthoscelides compressicornis (Schaeffer 1907); Lithraeus electus Bridwell (1952) with Lithraeus elegans (Blanchard 1851); Bruchus alboguttatus Motschoulsky (1874) with Meibomeus musculus (Say 1831); Bruchus bivulneratus Horn (1873) with Bruchus abbreviatus, inadvertently validated by Say = Sennius abbreviatus (Say 1824); Bruchus nigrinus Horn (1873), B. nictitans Motschoulsky (1874), and B. depressus Fall (1912) with Sennius cruentatus (Horn 1873); Bruchus pythonicus Pic (1913) with Stator pygidialis (Schaeffer 1907); and Bruchus biguttatus Fabricius (1801) = Bruchus biguttellus Schoenherr (1833) with Callosobruchus chinensis (Linnaeus 1758). Original spellings of the specific names of two species are revived: Megacerus pygidalis (Motschoulsky) nee pygidialis Pic, and Megacerus discoidus (Say) nec discoideus: authors. Bruchus lividus J. E. LeConte 1824 is placed in our list as an unrecognized species. Thirty-five new combinations are proposed.

“…However, we need to await more research in molecular and morphological character analysis to be made in order to have a firmer basis to build a phylogeny of these gibbous bruchids.

Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations

“…Sennius comprises 62 Neartic and Neotropical species, and Bridwell (1946) defined this genus by the presence of a carina extending near the base of the inner margin of the hind femur, and a tooth posterior to this carina. Subsequent authors such as Bottimer (1961Bottimer ( , 1968 and Johnson (1968) transferred eight species originally described in Bruchus Linnaeus, 1767 to Sennius. made the most relevant contribution by reviewing the North and Central American species of the genus.…”
