Width of collar, anterior pronotal lobe, and posterior pronotal lobe: 0.69; 1.04; 1.70, respectively. Scutellum brown; punctate; with short decumbent setae, and long erect setae as on anterior pronotal lobe. Hemelytra light brown, apex of corium darker; with short decumbent setae. Clavus with three rows of punctures and an incomplete row over distal half, between the inner and median rows. External corial margin slightly concave. Membrane brown, not homogeneously pigmented. Pleura dark brown, acetabular area, proepimeron and metepimeron lighter; punctate and setose, with abundant decumbent short silver setae. Protibiae with numerous minute tubercles on ventral surface. Coxae dark brown, tinged with red; femora, tibiae and tarsi light brown; femora mottled. Legs with semierect and erect setae, more abundant on distal tibiae and tarsi.

Abdomen brown. Abdominal length: 3.00. Pygophore ( Figs. 21–22): anterior margin of dorsal aperture rounded; inner projections with an anterior spine, more projected posteriorly. In lateral view: dorsal margin slightly declivent posteriorly. Parameres ( Figs. 23–24): blade gradually narrowing to apex, slightly curved; shank with setose inner projection, with setae on upper margin and basal portion of blade, and outer projection with two long setae. Aedeagus as in figure 25.

Distribution. Argentina, Brazil.

Remarks. Some specimens are darker, with dark brown anterior pronotal lobe and brown hemelytra, and with the anterior 2/3 of the corial margin and a subapical macula light brown. This is the only species in the genus that has mottled femora.
