Revisão, análise cladística e biogeografia de Coccoderus Buquet (Coleoptera, Cerambycidae)

Abstract

Revision, cladistic analysis and biogeography of Coccoderus Buquet (Coleoptera, Cerambycidae). A revision of the South American genus Coccoderus is presented. Ten species are recognized, of which C. sexguttatus, previously considered a synonym of C. amazonicus, is reinstated. Key to identification and illustrations of the species are added. The cladistic analysis, based on 31 morphological characters and 12 taxa, resulted in two equally most parsimonious cladograms and in both the monophyly of Coccoderus is supported by five synapomorphies. Notes on biogeography and maps of distribution are provided. Seven species occurs in sympatry on Cerrado, of which two species also occur in the Amazon Forest and two on the Atlantic Forest. Two species occurs only in the Amazon Forest and one species in the oriental forests of the Andes.
