Diagnosis

Dorsum presenting many small orangish-copper coloured tubercles; head with few green iridescent punctures in front of eyes and near mesial margins of head foliations. Pronotum with 2 + 2 almost indistinguishable lines present, oriented diagonally from posterior part of eyes to anterolateral angles of hemelytra, few scattered small iridescent punctures present on each side. Scutellum with 1 + 1 dark-reddish, iridescent green fovea on basal angles; hemelytra coria concolor with body, with a thin, Y-shaped mark (sometimes barely distinguishable). Anterolateral portions of connexiva without iridescent spots. Anterior margins of head foliations round and convex, mesial margins contiguous right after clypeus; anterior pronotal margin curved anteriorly, pronotal angles rounded and lateral margins slightly undulated or convex. Hemelytra costa before foliations small and rounded; wing membranes with many wrinkle markings, veins highly branched and rarely forming closed cells. At most narrow portions of connexiva are visible when wings are at repose. Body foliations undulated laterally and rounded postero-laterally in segments IV– VII; in females, foliations of laterotergites VIII overlapped (Figures 3, 7, 9).

Chromatic polymorphism

Most individuals (82) presented a pale yellow body colour with many small orangish-copper tubercles scattered irregularly, some regions of body and pronotum a bit darker, and a dark brown venter (Figures 3, 4, 13, 14). Two females (listed with a ‘~’ in the examined material) presented a main body colour similar to the individuals mentioned above, but with a distinct dark, diagonal line in head foliations and a concolorous line in the abdomen foliations encircling the body (Figure 7); dark lines are also visible ventrally (Figure 9). A male (Figure 8) and a female (indicated with a ‘^’ in the examined material) had a darker body colour, with many ring-like patterns (similar to plant growth rings) in different shades of orange and brown extending through head, head foliations, pronotum and, more conspicuously shaped as rings, on hemelytra, scutellum and body foliations; ventrally, ring patterns are also visible in foliations (Figure 10).
