ABSTRACT
The Brazilian species of Exoplectra Chevrolat, 1844, based on the morphological analysis of external characters and genitalia, are revised. Among the 37 species in the genera, 14 Brazilian species were analysed, including three new species. It was studied the type material of nine of them. The lectotypes of E. angustifrons Weise, 1895, E. calcarata (Germar, 1824), E. coccinea (Fabricius, 1801) and E. miniata (Germar, 1824) are designated. Exoplectra companyoi Mulsant, 1850 is revalidated; E. aenea (Fabricius, 1801), E. bernardinensis Brèthes, 1925, E. impotens Mulsant, 1850, E. luteicornis Mulsant, 1850 and E. irregularis (Crotch, 1874) are provisionally removed from the genus. Two new species from Brazil are proposed: E. columba sp. nov., from Paraná and E. bimaculata sp. nov., from Amazonas. Dicotomic key for species is presented as well as pictures and illustrations for the main structures used in the identification.
RESUMO
As espécies brasileiras de Exoplectra Chevrolat, 1844 são revisadas com base no estudo de caracteres morfológicos do exoesqueleto e genitália. Dentre as 37 espécies do gênero foram estudadas 14 brasileiras, incluindo as três propostas como novas. Foi examinado o material-tipo de nove espécies. São designados os lectótipos de E. angustifrons Weise, 1895, E. calcarata (Germar, 1824), E. coccinea (Fabricius, 1801) e E. miniata (Germar, 1824). Exoplectra companyoi Mulsant, 1850 é revalidada; E. aenea (Fabricius, 1801), E. bernardinensis Brèthes, 1925, E. impotens Mulsant, 1850, E. luteicornis Mulsant, 1850 e E. irregularis (Crotch, 1874) são provisoriamente removidas do gênero. São propostas duas novas espécies do Brasil: E. columba sp. nov., do Paraná e E. bimaculata sp. nov., do Amamzonas. É apresentada chave dicotômica para as espécies, fotos e desenhos das principais estruturas utilizadas para identificação.
