Martarega brasiliensis Truxal, 1949: 16, figs 3, 4 [original description].

Diagnosis.

Medium-sized species, male length 5.2–5.4 mm. Ocular commissure 1 / 2 of eye width. Ventral surface of third labial article pubescent. Scutellum with hyaline apex. Fore femur with a short spiniform seta. Ventral surface of middle trochanter with a patch of thin setae. Hemelytra of brachypterous specimens with medial longitudinal hyaline stripe narrow, slightly tapering from base of hemelytra up to membrane suture; hemelytral process stripe short, 20–30 % of hemelytral length; hemelytral process slightly shorter than membrane length (Fig. 9 B ).

Taxonomic notes.

Martarega brasiliensis is slightly larger than M. nessimiani Barbosa & Rodrigues, 2013 , a species with which it shares some similarities. Martarega brasiliensis has some distinctive features, like the pubescent labial surface and differences in the width of the hyaline band of the hemelytra.
