Two New Species of Dihammaphora (Coleoptera, Cerambycidae, Rhopalophorini), with Taxonomical and Geographical Notes for the Genus

Dihammaphora Chevrolat (Arc Nat 1:50–54, 1859) is one of the most diverse genera of Rhopalophorini, with 46 species. It is characterized mainly by species with antennae short and subserrated, with 10 or 11 antennomeres, prothorax cylindrical, and elytra punctuated. In this study, two new species of Dihammaphora are described and illustrated, new records are provided to 11 species, and taxonomic notes are given to six species of the genus. We examined 55 specimens and identified 16 species of the genus Dihammaphora, including Dihammaphora aureasp. nov. from Honduras, and Dihammaphora cruzisp. nov. from Brazil. The number of species of Dihammaphora is increased to 48, two of them in Central America, resulting in seven species for this region. In Brazil, 24 species are now recognized, being the country with the largest number of species of the genus. This study shows that there is still a deficit of knowledge about the diversity and distribution of Dihammaphora.
