Revision of the Anthonomus subgenus Anthonomocyllus Dietz (Coleoptera: Curculionidae)

The seventeen species of Anthonomus Germar in the subgenus Anthonomocyllus Dietz include Anthonomus tenuirostris Champion (= A. filirostris Champion, new synonymy), A. argentatus Gyllenhal, A. costulatus Suffrian (= A. elegans LeConte), A. contaminatus Boheman. A. dentipes Hustache (= A. murinofasciatus Voss, new synonymy), A. xanthoxyli Linell, A. leucostictus Dietz. A. aeroides Champion, A. caeruleisquamis Champion, and eight new species: A. acus, A. accola, A. azalus, A. guanita, A. pazmani, A. aeroides, A. cymatilis and A. caesius. The species occur in the Southern United States, Mexico, Central and South America and in the West Indies. Some are known to be associated with plants in the genus Zanthoxylum (Rutaceae). Lectotypes are designated for A. tenuirostris, A. filirostris, and A. dentipes, and a neotype is designated for A. murinofasciatus. Characters of the subgenus and of the species groups and included species are described and illustrated and a key to adults of the species is presented. The phylogenetic relationships of the species are reconstructed on the basis of apomorphic characters of adults.
