Rhinotora spiloptera Guimarães & Papavero

( Figs 5 D–F, 10)

Rhinotora spiloptera Guimarães & Papavero, 1966: 266 . Holotype ♂, MZUSP. Type-locality: Brazil, São Paulo, Salesópolis, Estação Biológica de Boracéia. Distr.— Brazil (São Paulo, Salesópolis). Refs—Guimarães & Papavero, 1966: figs 8–10 (male genitalia). Papavero 1967: 2 (catalogue); Almeida & Ale-Rocha 2011: 54 (male genitalia).

Diagnosis. Rhinotora spiloptera , similarly to R. paschoali sp. nov., has the male fore femur about four times longer than wide (i.e. narrower than in the remaining species). Rhinotora spiloptera shares with most Rhinotora species the presence of anterior orbital seta, the single supernumerary crossvein arising from the middle of R2+3, and the strong ventral setae on mid and hind femora. In addition, this species shares with lopesi , R. paschoali sp. nov., and R. travassosi , the complex pattern of brown and golden pruinose stripes and spots on scutum. Rhinotora spiloptera differs from its congeneric species by the triangular male cerci as shown by Guimarães & Papavero (1966).

Redescription. Head ( Figs 5 D–F). Mostly yellow, silvery to golden pruinose. Anterior reclinate orbital seta about as long as one fourth of posterior seta. Mouthparts brown, clypeus and palpus yellowish. Thorax ( Figs 5 D– E). Scutum brown with yellowish and reddish areas, golden setulose, with complex pattern of brown and golden pruinose stripes and spots; posteromedially golden pruinose. Scutellum triangular with apical and lateral spiniform protuberances; base of apical seta protuberant; yellowish brown, golden pruinose, apex and protuberances shiny. Wing ( Figs 5 E). Medial vein ratio: 0.44. Veins mostly dark brown with white and yellow areas; C mostly yellow, dark brown on distal two thirds of cell c. Membrane hyaline with dark spots. Cell r1 with eight simple supernumerary crossveins. Cell r2+3 with one simple supernumerary crossvein arising from the middle of R2+3. Legs ( Figs 5 D). Male fore femur about four times longer than wide. Distal third of mid femur with two rows of short strong ventral setae. Distal third of hind femur without strong ventral setae. Mid tibia with two or three distinct ventroapical setae. Abdomen. Generally brown in color, brown setulose. Male genitalia (illustrated by Guimarães & Papavero, 1966). Male cerci fused to each other, triangular in dorsal view. Surstylus single lobed, rectangular in lateral view, distal margin slightly concave. Phallus short, slender (Almeida & Ale Rocha 2011).
