(Figures 1–10, 33)
Hyboscarta tricolor Distant, 1909: 190; Metcalf, 1961: 507. Urubaxia tricolor Fennah, 1968: 184.
Measurements. Total length, 9.07 ± 0.15 (8.25–9.75); length of pronotum, 2.85 ± 0.05 (2.64–3.10); length of tegmina, 7.55 ± 0.11 (6.90–8.00); width of tegmina, 2.4 ± 0.06 (2.10–2.60).
Diagnose. Head, pronotum and scutellum orange-red; tegmina with basal third orange-red, costal and apical margins until the beginning of clavus brownish, median and posterior third translucent.
Description. Head orange-red (Figs 1–2), second and third rostral segments black; compound eyes black, rounded, arranged transversely; vertex smooth and rectangular, lacking median carina; ocelli black, closer to each other than to compound eyes; tylus smooth and rectangular, lacking median carina; antennae black, each pedicel sparsely setose, basal body of flagellum ovoid as long as wide, bearing one arista shorter than pedicel; postclypeus orange-red, inflated, convex in profile, with one longitudinal carina strongly marked, lateral grooves strongly marked; rostrum extending to mesocoxae. Thorax orange-red, basal area of mesosternum black, pronotum orangered, hexagonal, lacking median carina; anterior margin of pronotum straight, antero-lateral margins straight, postero-lateral margins slightly sinuous, posterior margin grooved; scutellum reddish with slight concavity centrally, lacking horizontal grooves; tegmina with basal third orange-red, costal and apical margins until the beginning of clavus brownish, median and posterior third translucent; apical reticulation slightly developed; hindwings hyaline with brownish venation, vein Cu1 abruptly thickened at base; legs orange-red, tibiae and tarsomeres black; metathoracic tibia with two lateral spines (basal spine smaller than spines in apical crown; apical spine larger than spines in apical crown); apical crown of spines on each tibia consisting of two rows; two rows of spines covered by setae on basitarsus; subungueal process present, triangular. Abdomen: pale to orange-red.
Male. Pygofer brownish, with a finger-like process between anal tube and subgenital plates (Fig. 3); subgenital plates long, wide at base and narrowing toward its apex, free for almost all its length (Fig. 4), with a short spinelike process on the inner margin medially (Fig. 3); paramere slender, with a dorsal spine pointed upwards and a median spine pointed downwards (Figs 5–6), both spines sclerotized; aedeagus robust with a straight shaft, slightly enlarged at base, covered by small scale-like spines (Figs 7–8).
Female. First valvulae of ovipositor long, slender and acute apically, bearing a rounded, basal process, slightly elongated and directed downwards (Fig. 9); second valvulae long, with apical third of dorsal margin serrate (Fig. 10); third valvulae short and wide, with long ventral setae.
Distribution. Brazil (Paraná, Santa Catarina, Rio Grande do Sul) (Fig. 33).
Remarks. An exclusive characteristic of U. tricolor is the shape of the subgenital plates in ventral view: the base of the plate is larger and narrows abruptly toward the apex than in other congeneric species.
