The Mexican and Central American species of Astaenomoechus (Coleoptera, Scarabaeidae, Ceratocanthinae)

摘要

The Mexican and Central American species of Astaenomoechus Martinez and Pereira are revised. Thirteen species are recognized of which four were previously described: A. setosus, A. nevermanni and A. americanus all described by Boucomont (1936) from specimens collected in termite nests in Costa Rica and A. estriatus, a South American species described by Paulian (1982) that ranges into Central America. Nine new species are recognized: A. cavei, A. hispidus, A. mixtus, A. multipunctatus, A. paniculus, A. parvosetosus, A. punctifrons, A. solisi and A. strigulosus. All species occur in Costa Rica except A. cavei, which is found in Honduras and Belize. Only one species, A. americanus, occurs in Mexico. All species are described, keyed and lectotypes are selected for the species described by Boucomont (1936).
