Martarega bentoi Truxal, 1949: 22, 23, figs 7, 8 [original description].
Diagnosis.
Male length 5.2–5.3 mm. Ocular commissure> 1 / 3 of eye width. Scutellum with hyaline apex; ventral surface of middle trochanter with a group of ensiform bristles. Hemelytra of brachypterous specimens with medial longitudinal hyaline stripe wide, tapering from base of hemelytra up to coastal margin in membrane suture; wide range of hemelytral process stripe, 25 % up to 40 % of hemelytral length; hemelytral process shorter than membrane length (Fig. 9 A).
Taxonomic notes.
Martarega bentoi is a medium-sized species that is very common and widespread in Brazil. It is very similar to M. uruguayensis (Berg, 1883), but can be distinguished from it after examination of the hyaline band on the hemelytra of coleopteroid specimens (Fig. 9 A), or the different position of the ensiform bristles on the middle trochanter. Also, it differs from Martarega brasiliensis and M. membranacea, the other two species found in this survey, by the combination of a scutellum with a hyaline apex and the middle trochanter with ensiform bristles.
