( Fig. 4 j; table 3)

Nezara rogenhoferi Stål 1872 , 40–41; Lethierry & Severin 1893, 166.

Nezara (Nezara) rogenhoferi: Kirkaldy 1909 , 117.

Acrosternum (Chinavia) rogenhoferi: Rolston 1983 , 108, 160–161; Frey-da-Silva & Grazia 2001, 112. Chinavia rogenhoferi: Schwertner & Grazia 2007 , 424, 432.

Diagnosis. Scutellum and pronotum with two wide yellow spots on the anterolateral regions. Yellow bands present on the external margins of the pronotum, hemelytra and connexivum.

Head. Margins of juga with a moderate concavity in front of eyes; apex of head semicircular, with a thin black line. Proportion of antennal segments: I<II<III<IV≈V. All antennal segments black. Rostrum surpassing the metacoxae. Tylus and base of head black.

Thorax. Anterolateral margins of pronotum with a strong submarginal dorsal depression and with a wide yellow band. Cicatrices of pronotum and external margins of propleura black. 1 + 1 black spots present close to the humeral angles.

Abdomen. Abdominal spine not reaching metacoxae. Spiracles brown. Connexivum with wide black bands on both anterior and posterior margins.

Male genitalia. Unknown.

Female genitalia. Gonocoxites 8 convex and laterotergites 9 concave. Posterior margins of the gonocoxites 8 slightly curved. Gonocoxite 9 slightly concave. Pars intermedialis slightly conical, as long as the capsula seminalis; capsula seminalis three times the width of pars intermedialis. Anterior annular flange shorter than the posterior and slightly curved towards the vesicular area. Posterior annular flange curved towards the pars intermedialis. Processes of capsula seminalis subequal in length, twice the length of pars intermedialis.

Adult size. 12–13mm.

Distribution. Brazil (RJ).

Material examined. Rio de Janeiro (RJ—Brazil), 1902, Wagner col., NHM (1♀); Ferraz de Vasconcelos (SP—Brazil), 1976, Ferraciolli col., MZSP (1♀); Rio de Janeiro (RJ—Brazil), 1956, NMNH (1♀).

Comments. The color pattern of this species is unique within the genus. The whole body is covered with small yellow macules, and with large yellow macules on the scutellum and pronotum.
