Pterovianaida duckensis

Guidoti & Montemayor, 2016 ( Fig. 31 View Figure 31 )

Diagnosis: Pterovianaida duckensis can be easily distinguished from P. melchiori by the wider paranota and the longer subcostal area reaching the apex of the membrane.

Redescription: Body: Head, pronotum dark brown, scutellum even darker; hemelytra, antennae, rostrum, legs and abdomen yellowish ( Fig. 31A View Figure 31 ). Head: Eyes fully developed, at least half of length of the head; antenniferous process small, less than one-sixth of pedicel length; pedicel, basi- and distiflagellomere subequal and more than two times the size of scape; bucculae roundish, widest anteriorly, bearing hairs on its border and few punctations displayed in a row, these big, almost the size of an ommatidia, posterior border concave ( Fig. 31F View Figure 31 ); rostrum reaching middle of abdomen ( Fig. 31B, C View Figure 31 ). Thorax: Projected towards head, covering part of the posterior region of the eyes; posterior lobe considerably raised; paranota always explanate, narrowing posteriorly; scutellum less than one-fourth the maximum width of pronotum ( Fig. 31E View Figure 31 ); sternal laminae narrow, punctate. Hemelytra: Clavus almost as wide as discoidal area, this, subequal to subcostal area; subcostal area extending to the apex of membrane, at least four times wider than costal area; costal area equally wide on its whole extent; all coriaceous regions equally and coarsely punctate; membrane with one inner row of punctures. Scent gland: Anterior brand gradually projected laterally, tip considerably projected, visible dorsally ( Fig. 31A, D View Figure 31 ), and tilted horizontally and enlarged, strongly inclined forward; posterior branch curved and enlarged on its tip; sulcus fading on anterior branch and deeply marked on posterior branch; evaporatorium barely projected on mesopleuron, occupying a straight, rectangular area ( Figs 16L View Figure 16 – 31C View Figure 31 ).
