A revalidation and new synonymies among some species of Brontostoma Kirkaldy (Hemiptera: Heteroptera: Reduviidae: Ectrichodiinae)

Based on the examination of types and additional specimens, the following new synonymies and revalidation are proposed in the genus Brontostoma Kirkaldy, 1904 (Hemiptera: Heteroptera: Reduviidae: Ectrichodiinae): Brontostoma discus (Burmeister, 1835) = Brontostoma nanus Carpintero, 1980, syn. nov.; and Brontostoma haematodes (Blanchard, 1846), sp. reval. = Brontostoma discus nigricans Carpintero, 1980, syn. nov. The previous synonym of Brontostoma venusta (Walker, 1873) with B. discus is confirmed. Brontostoma discus is recorded from French Guiana for the first time. Brontostoma cicheroi Carpintero, 1980 is very similar to B. discus, but because its holotype was not available for study no taxonomic conclusion could be achieved.
