Neolinycus michaelis HEINRICH 1971 View in CoL - Nat. Canad. 98: 1025, ♀. F e m a l e

F l a g e l l u m: Bristle-shaped, very slender, with white semiannulus on segments 6- 11, beyond middle scarcely widened and slightly flattened ventrally, strongly attenuated toward apex; basal segments moderately long, first segment 2,7 times longer than width at apex. Flagellum equal by length to front wing and 1,2 times shorter than body length.

H e a d: Head contour from front roundish, strongly narrowed downwards, 1,2 times wider than height; eyes very large; genae from front 5 times less than height of eye; internal margins of eyes parallel, with slight concave opposite antennal cavities; head contour from above transversal, 1,9 times wider than length. Vertex from lateral gradually slanting down to reduced in middle, low occipital carina; temples from above very short, more than 3 times shorter longitudinal diameter of an eye in middle, roundly nar- rowed backwards, from lateral slightly broadened downwards; occipital carina from above angularly impressed behind level of eyes, but not reach level of ocelli, meeting with hypostomal carina far from mandible base; malar space longer than mandible base width; mandibles behind base strongly linearly narrowed with very small lower tooth; clypeus strongly convex relative to lower level of lateral fields above clypeal foveae, approximately with equal breadth and width, separated from middle field of face by impression, with thin, straight apical margin; clypeal foveae small, deep; labrum short, broad, rectangular; middle field of face practically not expressed, broad, more than two times narrower than lateral fields in middle; antennal cavities moderately impressed, reach borders of eyes but far not reach front ocellus level, with roundish tubercles laterally and without tubercle between antennal fossae; ocelli normal, ocellar triangle slightly elevated. Surface of clypeus, face and frons with dense punctures with microsculpture and only just visible shine (almost matt).

T h o r a x: Collar of pronotum short, transverse furrow shallow. Mesonotum strongly convex, with equal length and breadth, notauli distinct only in front third; surface of mesonotum densely punctured, with microsculpture (delicate coriaceous), slightly shining; subalarum thin, but not sharpened; speculum smooth, shining, area of mesopleural fovea not broadly and not deeply impressed; sternauli distinct, reach approximately to middle of mesopleurae; surface of mesopleurae delicate wrinkled, shining; scutellum slightly convex, gradually sloping to postscutellum, laterally carinated up to apex, surface delicate coriaceous with sparse punctures. Hind margin of metanotum with distinct broad triangle projections opposite lateral longitudinal carinae. Propodeum from lateral gradually slanting to apex, horizontal part considerably shorter than area posteromedia in middle; carinae of propodeum, with exception of coxal, distinct; area superomedia hexagonal, wider than length, costulae approximately in middle of area superomedia; area dentipara with distinct denticle at apex, its apical carina high, widened; spiracles small circular, equal 0,4 breadth of area at place of spiracle, of equal length and breadth. Surface of propodeum delicate wrinkled, metapleurae delicate wrinkled, coriaceous.

L e g s: Moderately long and slender. Claws small, broad at base and slightly curved at apex.

W i n g s: Areolet quadrangular, almost symmetrical (external vein of apex some shorter than internal); stigma broad, light; radius almost straight, short; radial cell broad; nervulus interstitial; ramulus distinct; membrane of wing hyaline, veins light. Front wing 1,3 times shorter than body length.

A b d o m e n From above uniformly longish-oval, flattened dorso-ventrally; second tergite shorter than width at apex; apical tergites not hidden; sheath of ovipositor only just protrude. Petiolus distinctly flattened, from lateral with gradual passage to postpetiolus, almost straight, lateral carinae distinct, surface between them sculpturated by ribs; from above petiolus gradually broadened to postpetiolus; middle field distinctly elevated, but not carinated, lateral fields many narrower than middle field; surface of postpetiolus delicate coriaceous with separate punctures, shining. Gastrocoeli shallow, thyridia distinct, removed from base of second tergite, transverse, interval approximately equal to breadth of thyridia; lunulae distinct, big; surface of tergites 2 and 3 densely and uniformly punctured by big punctures, slightly shining; third tergite with superficial punctures, other tergites with only just visible punctures. Hypopygium with longitudinal fold and membranous apex.

C o l o r a t i o n: Body of females ferruginous with white coloration on head and thorax: face, clypeus, external orbits, frontal orbits very broadly, collar, lateral and upper margins of pronotum, closed from behind stripes along notauli, scutellum and postscutellum, tegulae, subalarum, spots on mesopleurae, front and middle coxae.

S i z e: Body length: 5,1; front wing: 4,0, length of flagellum: 4,2 mm.
