Revision of the Neotropical Cholinae. The subgenus Cholus (Cholus) (Coleoptera, Curculionidae). Bulletin of the AMNH ; v. 158, article 1

Abstract

"Cholus is considered tentatively to include two subgenera, Cholus Germar and Aphyoramphus Guérin-Méneville, but only Cholus is revised in the present paper. Keys are given to the 63 species of the subgenus Cholus, which are arranged in 10 species groups, to the genera of the Cholini and Cholomini, and to the three tribes of Cholinae. Dionychus is placed in synonymy with Cholus. Fifteen new species are described from six countries of South America: acuminatus, apicalis, cephale, cinereus, coloreus, grandis, hirsutus, indubitatus, leopardinus, longus, magnidens, planus, pubescens, sagittarius, and varians"--P. 5.
