Distribution: Brazil, Paraguay, and Argentina ( Fig. 21 ).

Head. Mandibular plates ventrally parallel.

Thorax. Posterolateral angles and posterior margin of pronotum forming a semicircle. Evaporative area yellowish to dark brown, with few and minute setae; peritreme yellowish to dark brown. Costal margin of hemelytra slightly sinuous.

Abdomen. Spots of the connexiva without a clear delimitation, ranging from light red on the anterior margin of the segments to dark red on the posterior margins. Pygophore at rest leaving visible an area equivalent to its own length of the urotergite VII, in ventral view.

Genitalia. Male. Pygophore dark yellow, with brown spots laterally and blackish distally. Dorsal rim of pygophore sub hexagonal. Posterior surface of the pygophore, in lateral view, slightly projected subapically. Cuplike sclerite projected as much as its own width in the lateral view of the pygophore. Parameres robust, light yellow, except for the apex of the head and basal region, dark brown; head short, about one-fifth of the total length of the paramere, turned abruptly to the inner side, and with setae distributed ventrally and dorsally. Ventral sclerotization of the phallotheca as a regular shield. Basal plate triangular, little sclerotized, except for the upper portion more sclerotized with about one-fourth of the transversal bridge thickness; sclerotization of the central part of the ductifer longer than half of the length of the ligamentous processes. Processes of conjunctiva entirely membranous.

Measurements (mm), male and female, respectively: Total length: 21.4–24 and 22.6–27.3; width, on the posterior margin of the IV abdominal segment: 11.1–12.5 and 11.4– 15.2. Head length: 1.7–2.0 and 1.6–2.3; width: 2.2–2.4 and 2.2–2.5. Interocular distance: 1.3–1.4 and 1.3–1.5. Antennomeres length I: 3.5–4.5 and 4.0–4.9; II: 3.6–4.7 and 4.1–5.5; III: 3.2–3.9 and 3.2–4.4; IV: 2.4–2.9 and 2.9–3.5. Pronotum length: 7.4–8.8 and 8–10.1; width: 9.5–11.6 and 10.5–13.5. Scutellum length: 2.2–2.6 and 2.4–3.3; width: 2.9–3.5 and 3.1–4.
