Pterovianaida Montemayor & Carpintero, 2007

Diagnosis: This genus is characterized by the abundant long hairs on the head, which is remarkably declined, by the presence of paranota constricted in the middle and a conspicuously raised distal part of the pronotum and by the scent gland that is laterally projected with the edges of the tips of both anterior and posterior peritreme branches enlarged.

Redescription: Head: Triangular in dorsal view, pubescent, with large, long hairs on vertex, once referred as macrochaetae; pedicel subequal to basiflagellomere and to distiflagellomere, each one of these more than twice the length of scape; eyes fully developed, compound; rostrum reaching at least the second abdominal segment. Thorax: Posterior lobe strongly raised, pubescent; entirely punctate; collar distinct, punctate; anterior border straight, posterior convex; paranota explanate, smooth, constricted in the middle, between the anterior and posterior lobes. Hemelytra: Macropterous, clavus and vein-less membrane well-defined; scale-like projections on hemelytra border; punctate on coriaceous parts; membrane with one inner row of punctations; hypocosta broad and finely punctate. Scent gland: Anterior branch gradually projected laterally, tip much more projected than base; tip tilted horizontally, large, conspicuously inclined frontwards; posterior branch usually curved, with enlarged tip. Legs: Femora same width of the other segments; tarsi two segment, second segment remarkably longer and many times the length of the first. Abdomen: Rectangular, covered with hairs; spiracles located ventrally near lateral margins of abdominal sternites, these straight.

Type species: Pterovianaida melchiori Montemayor & Carpintero, 2007 .

Distribution: Known from Brazil and Peru ( Fig. 18C ).

Discussion: Pterovianaida was described by Montemayor & Carpintero (2007) based on a single slide-mounted specimen. Additionally, it is clear the authors were not aware of macropterous species described by Schuh et al. (2006) when proposing this genus. However, the genus gained its second species almost ten years after its original description, based on
