Urubaxia solo Paladini & Carvalho n.sp.

( Figures 11–22 , 33 )

Measurements. Total length, 10.42 ± 0.26 (9.58–11.25); length of pronotum, 3.07 ± 0.07 (2.77–3.30); length of tegmina, 8.61 ± 0.19 (7.90–9.30); width of tegmina, 2.51 ± 0.04 (2.40–2.70).

Diagnose. Head orange-red; in males, anterior third of pronotum orange and posterior third black, and in females, pronotum entirely orange; basal third of tegmina orange, costal area black, median third and beginning of apical third translucent.

Description. Head orange ( Figs 11–14 ); second and third segments of rostrum 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; each antenna black; each pedicel sparsely setose, basal body of flagellum ovoid as long as wide, bearing one arista shorter than pedicel; postclypeus orange, inflated, convex in profile, with one longitudinal carina strongly marked, lateral grooves strongly marked; rostrum extending to the mesocoxae. Thorax orange; pronotum lacking median carina, in males with frontal area orange and posterior area black ( Figs 13–14 ) and in females entirely orange ( Figs 11–12 ); anterior margin of pronotum straight, antero-lateral margins straight, postero-lateral margins slightly sinuous, posterior margin grooved; scutellum orange with slight concavity centrally, lacking horizontal grooves; tegmina with basal third orange, costal area black, median third and beginning of apical third translucent, apical margin brownish; apical reticulation poorly developed; hindwing hyaline with brownish venation, vein Cu1 thickened at base; pro and mesothoracic legs orange, tibiae and tarsi black; metathoracic tibia orange, tibia and tarsus black apically, with two lateral spines (basal spine smaller in size than spines in apical crown; apical spine larger than spines in apical crown); apical crown of spines on each tibia consisting of two rows; basitarsus with two rows of spines covered by setae; subungueal process present and triangular. Abdomen: brownish.

Male. Pygofer brownish, with a rounded process between the anal tube and subgenital plates ( Fig. 15 ); subgenital plates long, wide at base and narrowing toward its apex, free for almost all its length ( Fig. 16 ), with a short and sclerotized spine-like process on inner margin medially ( Fig. 15 ); paramere slender, with a dorsal, sclerotized and robust spine, pointed upwards and a ventral spine pointed downward ( Figs 17–18 ); aedeagus robust, with a straight shaft, slightly enlarged basally, covered by small scale-like spines ( Figs 19–20 ).

Female. First valvulae of ovipositor long and slender, acute apically and one basal process, rounded, elongated and directed downward ( Fig. 21 ); second valvulae long, with apical third of dorsal margin serrate ( Fig. 22 ); third valvulae short and wide, with long ventral setae.

Distribution. Brazil (Rio de Janeiro) ( Fig. 33 ).

Remarks. This species is morphologically similar to U. tricolor , differing from it by the slender and sclerotized process on the dorsal margin of the subgenital plate and by the insertion of the paramere ventral spine on the paramere ventral margin and its lightly sclerotized aspect. U. solo n.sp. shows color dichromatism: the posterior half of pronotum is black in males and entirely orange in females, and females show a transverse black stripe on the anterior third of tegmina, whereas in males this area is yellowish.

Etymology. The solo is a noun in apposition; the epithet is relative to the paramere with only one sclerotized spine, and in honor of the sci-fi character Han Solo from Star Wars© saga—we grieve his death in the movie The Force Awakens.
