Matangia gen. nov.

Type species. Idioscopus capriliana Viraktamath & Murphy , here designated.

Diagnosis. Externally similar to the genus Idioscopus , but differs in the male genitalia. Aedeagal shaft without apical or basal processes, male pygofer with or without ventral process and style with anterior part about half as long as distal process (see also Remarks).

Description. Greenish yellow or brown with reddish brown or dark brown markings on head, mesonotum or without such markings.

Crown parallel sided or medially slightly longer than next to eyes, transversely rugose, 4.0–4.8× as wide as long medially, fore margin rounded to face. Face including eyes wider than long, area dorsad of ocelli rugose; Lora slightly raised. Clypellus slightly widened distally, slightly exceeding outer margin of genae. Antenna without flagellar disc. Labium slender, either reaching or slightly exceeding metacoxae. Ocelli closer to adjacent eye than to each other. Pronotum shorter than mesonotum, about 2.0–2.5× as wide as long medially, shagreen, posterior margin shagreen. Mesonotum about as long as or slightly shorter than combined length of crown and pronotum, mesoscutellum irregularly rugose. Forewing with 2 or 3 subapical cells and 4 apical cells. Meta femur distal macrosetae 2+1; meta tibia with setal row AD 6, PD 11±8, AV 7–8; meta basitarsomere with two platellae on apical transverse row flanked by one seta on either side ( Figs 31E , 32E ). Tergal and sternal apodemes at base of abdomen in male well-developed. Female sternite VII wider than long medially, with posterior margin convex ( Figs 61 PQR).

Male genitalia. Anterior dorsal apodemes well-developed, pygofer incised at base, longer than height, without or with ventral processes, ventral margin not sinuate. Subgenital plate more or less of uniform width, with hair-like setae along margin, as long as or longer than pygofer. Style long, curved, anterior part about half as long as apical process, latter tapered distally with ventral surface serrated in mid-region and dorsal surface with thin setae in apical region. Aedeagus with poorly developed preatrium, dorsal apodeme in lateral view large, wider than width of shaft and at least 0.75× as long as shaft, aedeagal shaft tapered distally in lateral view, almost straight in basal 0.75 length then curved slightly anteriorly, without processes, proximal end with strong concavity for articulation with connective. Anal collar process well-developed, sclerotized with bilobed or bifurcate distal end.

Female genitalia. Ovipositor projecting well beyond apex of pygofer. Valvula I almost straight or slightly curved, tapering distally with oblique strigae reaching dorsal margin (strigae becoming reticulate for a short distance preapically near dorsal margin in M. capriliana and M. thapai ), sculpturing extending to distal 0.5 length ( Figs 68 IJ, MN). Valvula II straight or slightly curved dorsally, with well-developed toothed area confined to distal 0.25 to 0.33 length, teeth either close to each other or well separated from each other ( Figs 68 KL, OP).

Etymology. This genus is named after the Hindu Goddess Matangi; gender feminine.

Remarks. Matangia gen. nov. resembles the Palaearctic genus Balcanocerus Maldonado-Capriles in the shape of the aedeagus, but differs in the following aspects: a) crown and upper part of face are rugose (shagreen in Balcanocerus ); b) metafemur distal macrosetae 2+1 (in Balcanocerus 2+0); c) aedeagus with dorsal apodeme distally expanded laterally (not so expanded in Balcanocerus ).
