Urubaxia Fennah, 1968

Urubaxia Fennah, 1968: 173 . Type species: Hyboscarta tricolor Distant, 1909 , by original designation.

Description. Head orange or red with second and third segment 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; pedicel of each antenna sparsely setose; basal body of flagellum ovoid as long as wide, bearing one arista shorter than pedicel; postclypeus inflated, convex in profile, with one longitudinal carina, lateral grooves strongly marked; rostrum extending to the mesocoxae. Pronotum hexagonal, lacking median carina; scutellum reddish with slight central concavity centrally, lacking horizontal grooves; tegmina three times wide at level of apex of clavus, hindwing vein Cu1 abruptly thickened at base; legs with metathoracic tibia with two lateral spines (basal spine smaller in size to spines in apical crown; apical spine larger than spines in apical crown); apical crown of spines on tibia consisting of two rows; basitarsus with two rows of spines obscured by long setae; subungueal process present and triangular.

Male. Pygofer with a process between the anal tube and subgenital plates, these ones long, wide basally and narrowing toward the apex, free for almost all its length, with a process on the inner margin, medially; paramere slender, with a dorsal spine pointed upwards and another spine pointed downwards; aedeagus robust with a straight, cylindrical shaft, slightly enlarged at base, covered by small scale-like spines; apical gonopore.

Female. Ovipositor with first valvula long and slender, acute apically, and with one basal process directed downwards; second valvula long, with apical third of dorsal margin serrate; third valvula short and wide, with long ventral setae.

Remarks. This genus can be easily distinguished from other genera of Ischnorhininae by the shape of the paramere, with two divergent processes. The morphology of pygofer, subgenital plates and aedeagus are quite similar to the species of Tunaima . Species of Urubaxia are usually collected in high altitude zones (900–2400m).
