Abstract
In this study, two new genera of Desmiphorini (Lamiinae) are proposed: Cleidaria gen. nov., to include Cleidaria cleidae sp. nov. from the state of Chiapas in Mexico, and Obscenoides gen. nov. for Desmiphora (D.) comptaMartins & Galileo, 2005Martins, U.R. & Galileo, M.H.M. 2005. Contribuição para o conhecimento dos Desmiphorini (Coleoptera, Cerambycidae, Lamiinae) da Região Neotropical. Papéis Avulsos de Zoologia, São Paulo, 45(19): 243-248.. The shape of tarsal claws of Cleidaria cleidae sp. nov. (abruptly narrowed from basal half) is so far, not found in any current genera of the tribe. With respect to Obscenoides compta (Martins & Galileo, 2005Martins, U.R. & Galileo, M.H.M. 2005. Contribuição para o conhecimento dos Desmiphorini (Coleoptera, Cerambycidae, Lamiinae) da Região Neotropical. Papéis Avulsos de Zoologia, São Paulo, 45(19): 243-248.) comb. nov., the genitalia of males have an unusual shape with non-retractile parameres. The character combination related to this genital structure is unknown to us in other species in the family, and hypotheses about its function are suggested.
