Montemayor, Sara I. & Carpintero, Diego L., 2007, A new macropterous genus with a new species of Vianaididae (Heteroptera, Tingoidea, Vianaididae) from Peru, Studies on Neotropical Fauna and Environment 42 (2), pp. 133-136 : 133-135

Pterovianaida gen. n.

Head ( Figure 1 ). Triangular in dorsal view, convex above. Eyes well developed, in dorsal view drop-like, in lateral view ovate, higher than wide; ocelli absent. Bucculae very narrow, subrectangular in lateral view, in ventral view subparallel, contiguous. Antennae ( Figure 2 ) moderately long and slender, segments II, III and IV subequal, approximately three times segment I. Segment I barrel-shaped, segment II slightly claviform, segments III and IV cylindrical, wider at the center.

Thorax. Pronotum ( Figure 1 ) with anterior lobe smooth, weakly elevated; posterior lobe with small scattered punctuations; collar slightly raised. Paranota carina-like. Scutellum well developed with small scattered punctuations. Metathoracic scent gland ( Figure 4 ) provided with a Y-shaped peritreme that covers the entire metapleuron. Fore wings ( Figure 3 ) with defined membrane and clavus, punctuated, with long, erect, scattered hairs except for membrane; outer margins serrated. Clavus welldeveloped and punctuated, costal area narrow with one row of small rounded punctuations; subcostal area narrow at base of hemelytra, widest at base of membrane, from there gradually narrowing down following the margins of the costal area but not surrounding it completely; discoidal area triangular, widest part with six rows of punctuations; membrane without nervures.

Legs. Slender, procoxae more separated from mesocoxae than the latter from metacoxae.

Abdomen. Ventrally covered with scattered long, white, semidecumbent hairs.

Type-species by present designation. Pterovianaida melchiori sp. n.

Etymology. Ptero - in allusion to their macropterous condition; vianaida - to indicate yet another genus in the family.
