The Maculipennis species group is composed of nine Dichroplus species (D. maculipennis (Blanchard), D. vittatus Bruner, D. pratensis Bruner, D. porteriMaculipennis species group is composed of nine Dichroplus species (D. maculipennis (Blanchard), D. vittatus Bruner, D. pratensis Bruner, D. porteri(Blanchard), D. vittatus Bruner, D. pratensis Bruner, D. porteri Liebermann, D. obscurus Bruner, D. conspersus Bruner, D. robustulus (Stal), D. vittiger (Blanchard), and D. silveiraguidoi Liebermann). Desmopleura concinnaD. obscurus Bruner, D. conspersus Bruner, D. robustulus (Stal), D. vittiger (Blanchard), and D. silveiraguidoi Liebermann). Desmopleura concinna(Blanchard), and D. silveiraguidoi Liebermann). Desmopleura concinna Scudder is here considered to be a junior synomym of Dichroplus vittiger (Blanchard). The Maculipennis group is widely distributed in Argentina, mostly in the Pampas, northern Patagonia, Monte and Espinal biogeographic regions, southern Brazil, Uruguay, and central Chile, with a few records from Bolivia and Paraguay. Based on a unique combination of characters from the phallic complex and the external morphology, it appears to constitute a monophyletic group. The species are mostly differentiated by their external morphology and slight differences of the male genitalia.Dichroplus vittiger (Blanchard).
