Papunega armocula Gnezdilov et Soulier-Perkins , sp. nov.

( Figs 13–19)

Type material. ♀, holotype, Papua New Guinea, Wilhelm Mt, 200 m, 5°44'28''S 145°19'46''E, 7.XI.2012, Malaise trap. MNHN (EH) 22061.

Description. Metope wide, slightly enlarged above the clypeus, with thick subapical transverse carina and distinct sublateral carinae altogether horseshoe-shaped, also with a tiny median carina reaching almost middle of metope ( Figs 14, 19 ). Median and sublateral carinae not reaching metopoclypeal suture. Two indistinct rows of tubercles between lateral margins (keels) and sublateral carinae of metope present. Lateral margins (keels) of metope raised, slightly leaf-shaped above the pedicel. Metopoclypeal suture complete, distinct. Postclypeus large, with weak medial groove. Pedicel elongately cylindrical. No ocelli. Coryphe transverse, nearly 1.5 times as wide as long medially, anterior margin widely convex, posterior margin obtusely angulately concave ( Figs 13, 16 ). Coryphe with two large tubercles near its posterior margin besides of median line. All margins of coryphe keelshaped. Pronotum 1.3–1.5 times as long as mesonotum, with weak median carina, anterior margin obtusely angulately convex, keel-shaped, posterior margin slightly concave ( Figs 13, 16 ). Paradiscal fields of pronotum very narrow behind the eyes. Paranotal lobes of pronotum wide. Mesonotum with weak median and lateral carinae. Fore wings elongate, slightly narrowing to rounded apices, without hypocostal plate ( Figs 15, 17 ). Basal cell elongately oval. Radius with 2 main branches (furcates near to basal cell, posterior branch (R2) also shortly furcates apically), median with 5 branches (first furcation near wing middle), cubitus anterior with 2 branches (furcates near wing middle). Many transverse veinlets are present between main longitudinal veins. Clavus opened (postcubitus + first anal vein joining cubitus posterior at apex of clavus). Hind wings well developed (3-lobed). Hind tibia with 2 lateral spines distally ( Fig. 17 ) and with 7 spines apically. First metatarsomere with 2 lateral and 7 intermediate (in entire row) spines apically.

1 mm Coloration. General coloration light brown yellowish ( Figs 16–19 ). Metope in frontal view black between its upper margin and subapical transverse carina; brown below; with a wide median whitish band bordered with darker brown one between sublateral carinae at the level of antennae ( Fig. 19 ). Two tubercles on coryphe, median carina of pronotum, lateral carinae of mesonotum and scutellum, and legs light yellow. Postclypeus brown frontally. Anteclypeus totally brown. Paranotal lobes of pronotum each with large black spot. Fore wings with brown or dark 21 brown cells disseminated ( Figs 16, 17 ). Hind wings with dark brown veins. Abdominal sternites IV–VI dark brown medially ( Fig. 18 ). Hind margin of sternum VII dark brown. Gonoplacs with dark brown margins. Apices of rostrum and anal tube dark brown. Apices of leg spines black. Apices of third tarsomeres of middle and hind legs and claws of all legs dark brown.

Female genitalia. Hind margin of VII sternum almost straight, weakly convex ( Fig. 18 ). Gonoplacs convex. Anal tube long and narrow. Anal column short.

Total length. 6.2 mm.

Etymology. Species name is derived from Latin “armus” (shoulder) and “oculus” (eye) referring to the large black spots on the paranotal lobes of the pronotum.
