Diagnosis.

Male length 15–16 mm. Wide rectangular punctuated area on scutellum. Middle femur with short and dark pubescence; anteapical protuberance weakly developed. Apex of metaxyphus variable, acute to spatulated.

Taxonomic notes.

This species shows some variation in general and hemelytral color pattern, from light-yellow to dark brown, with deep punctures on the scutellum. The amount of these punctures seems to follow the overall color of the specimens. It resembles E. lanemeloi Barbosa, Ribeiro & Nessimian, 2017 , as both species show middle femur with short setae and poorly developed apical spur, but can be distinguished from it by the coarser aspect and different pattern of the scutellar punctures, the different pattern of the punctuated area on the scutellum, and by differences in paramere shape. Differences between E. brasiliensis and the other species occurring in the study area, E. tricomerus , are provided in the key.
