Parahiranetis gen. nov.

Type species. Parahiranetis salgadoi sp. nov., by present designation.

Diagnosis. General appearance: wasp-mimetic. Head elongate, 1.6 to 1.8 times as long as wide across eyes. Postocular portion of head, in dorsal view, narrowing gradually to form collum, with a pubescence of long hairs on postocular portion, dorsally, and on gula, ventrally. Postantennal spines small, acute. Legs slender and elongate; fore femur subequally longer than head and pronotum together; femora thicker basally. Hemelytra long, surpassing abdomen by about a quarter of the length of the body.

Description. Head elongate, 1.6 to 1.8 times as long as wide across eyes; integument shiny, with sparse long and short, straight or somewhat curved blackish setae and hairs; these latter much denser, forming pubescence of long blackish hairs on postocular portion, dorsally, and ventrally on gula. Anteocular portion slightly longer than postocular; the latter, in dorsal view, narrowing gradually to form collum. Clypeus straight. Antenna inserted at level of upper third of eye; antennal segments I and II [other absent] slender. Postantennal spines small, somewhat acute. Transversal (interocular) sulcus deep, well marked, curved laterally, reaching eyes approximately at distal third. Labium stout, curved, reaching prosternum at proximal or mid portion; segment II (first apparent), thickest, straight, reaching level of middle portion of eyes, slightly longer than segment III; segment III somewhat curved, reaching level of prosternum; segment IV shortest, triangular, tapering.

Thorax. Midlongitudinal sulcus shallow anteriorly, deep distally; transverse sulcus well defined; anterior margin of mesepisternum flat, without tubercle (i.e., ‘plica’); stridulitrum attaining level of middle of fore coxa. Scutellum subtriangular, with median shallow depression.

Legs slender and elongate; coxae and specially trochanters with sparse long straight hairs and dense erect brush-like setae ventrally; fore and hind femora and tibiae straight; mid femora and tibiae somewhat curved in dorsal view; femora thickened basally in proportion of approximately 1.7 times the thickness on median portion of the segment; femora slightly dilated subapically too, with sparse long straight hairs and dense erect brush-like setae ventrally, which are quite longer on basal portion, and restricted to the latter on hind femur; fore tibiae somewhat enlarged at apex, with a small apical spur on anterior surface; mid tibiae with uniform thickness; hind tibiae somewhat enlarged on basal half and narrowing a little to apex; tarsi three-segmented.

Hemelytra long, surpassing abdomen by about half length of membrane and a quarter of length of body.

Abdomen elongate; spiracles rounded.

Female external genitalia. Spiracle 8 on paratergite 8; syntergite 9/10 nearly vertical; first gonocoxa wide; first gonapophysis narrowing to posterior margin, reaching basal fourth of first gonocoxa.

Etymology. The name of the new genus was given in reference to its general similarity to Hiranetis .
