Abstract

ARIAS-BURITICA, Jorge Armando  and  VAZ-DE-MELLO, Fernando Z. Redescription of Dichotomius camposeabrai and D. nemoricola (Coleoptera: Scarabaeidae: Scarabaeinae), with notes on their systematic position. Rev. Mex. Biodiv. [online]. 2012, vol.83, n.2, pp.387-395. ISSN 2007-8706.

The redescription of Dichotomius camposeabrai Martinez, 1974 and D. nemoricola (Pereira, 1942) is presented, including the description of the female of the first species and the male of the second so far unknown. For each species, illustrations of the male habitus, male genital organ, the sclerites of internal sac and head and pronotum of female are presented. Information about geographical distribution and some comments are available. In addition the transfer of D. camposeabrai to the bitiensis group is proposed and discussed, given the similarities of the external morphology and male genital organ with those of D. nemoricola.

Keywords : male genital organ; sclerites of internal sac; copulatrix lamella; bitiensis group.
