Cyclolabellus pertenuis HEINRICH (Plate 29)

Cyclolabellus pertenuis HEINRICH 1974 - Ann. Zool. Warszawa 32: 147, ♀. F e m a l e

F l a g e l l u m: Very long and slender, with 30 segments, scarcely widened and very slightly flattened ventrally beyond middle, gradually attenuated toward apex, with white semiannulus on segments 8-13; basal segments very long, first segment 4 times longer than width at apex, all segments longer than wide. Flagellum longer than front wing and body length.

H e a d: Head contour from front roundish, 1,3 times wider than height; genae from front short, 0,2 height of eye; genae strongly narrowed toward mandibles base; eyes very large; head transversal, from above 2,3 times wider than length. Vertex from lateral gradually slanting down to occipital carina; temples behind eyes (from above) very short, strongly, but roundly narrowed backwards, from side parallel to hind margin of eye, 2,4 times shorter than longitudinal diameter of eye at middle; occipital carina from above slightly angularly impressed, not reach level of eyes and hind ocelli, sharp, but not high all round, meeting with hypostomal carina almost on mandible base; malar space approximately equal to mandible base width; mandibles thin, evenly narrowed behind base, lower tooth moved inside; clypeus moderately convex, transversal, 2,2 times wider than length, apical margin straight, lateral corners rounded, distinctly separated from face; clypeal foveae rather large, deep; labrum broad, rounded, but short, equal by breadth to clypeus front margin; middle field of face only just elevated, slightly separated from lateral fields, only just wider than lateral fields in middle; antennal cavities small, slightly impressed, not reach borders of eyes and very far not reach front ocellus level, laterally above antennal fossae with tubercles and tooth between antennal fossae; margins of antennal fossae high elevated; ocelli of normal size, diameter of lateral ocellus approximately equal to distance from ocellus to eye; ocellar triangle practically not elevated. Clypeus and lateral fields densely superficially punctured; middle field superficially wrinkly-punctured; frons with only just visible wrinkled; surface of head shining.

T h o r a x: Collar of pronotum short, transverse furrow narrow, moderately deep. Mesonotum moderately convex, some wider than length, notauli only just marked in front third; surface of mesonotum very densely punctured, slightly shining; subalarum thin, but not sharpened; area of speculum slightly shining, sculpturated as other part of mesopleurae; area of mesopleural fovea broadly and deeply impressed; sternauli slightly impressed in front third; mesopleurae densely wrinkly-punctured, almost matt; scutellum convex, laterally carinated up to apex, gradually sloping to postscutellum, horizontal part with superficial punctures. Hind margin of metanotum with very long bacilliform projections opposite lateral longitudinal carinae. Propodeum from lateral gradually sloped; length of horizontal part approximately two times shorter than area posteromedia in middle; carinae of propodeum developed, with exception of lacking costulae and coxal carina; area superomedia longer than width (1,4 times), narrowed backwards, from front rounded; area dentipara with only just visible denticle at apex; spiracles small, circular, only just longer than width, equal 0,4 breadth of area spiraculifera at place of spiracle. Surface of propodeum very densely wrinkly-punctured, slightly shining; surface of area superomedia with slight rugosity, shining, metapleurae very densely punctured to wrinkled.

L e g s: Quite long, moderately slender.

W i n g s: Areolet big, quadrangular (almost pentagonal with very narrow base), almost symmetrical; stigma broad, moderately darkened; radius slightly curved, sinuous, long; nervulus interstitial; ramulus only just marked; membrane of wing hyaline, veins dark. Front wing some shorter than body length.

A b d o m e n Longish-oval from above, dorso-ventrally compressed, second tergite with approximately equal length to breadth at apex, apical tergites not hidden, visible from above; sheath of ovipositor practically hidden (only just visible from above). Petiolus flattened, from lateral with distinct, but gradual bend, without sharp break; dorsal and ventral lateral carinae sharp; from above petiolus gradually broadened to postpetiolus; middle field of postpetiolus distinctly elevated, with slight rugosity, two times wider than lateral fields; postpetiolus shining. Gastrocoeli distinctly impressed, rather long, approximately quadrangular; thyridia slightly expressed, interval some wider than thyridia width, slightly wrinkled; lunulae distinct, moderately large, situated at hind third of tergite; surface of second and third tergites densely punctured with exception of apical parts; fourth tergite with superficial punctures, other smooth. Hypopygium from below triangle, sharply pointed, without longitudinal fold, flat, membranous at apex.

C o l o r a t i o n: Head and thorax black with yellow pattern: corners of clypeus, ex- ternal and internal orbits (broadly), upper and lower margins of pronotum, scutellum, subalarum; abdomen ferruginous with darkened in most part first and tergites 5-6; tergites 5-6 with yellow margin apically, 7th in most part yellow.

S i z e: Body length: 6,0; front wing: 5,4; flagellum: 6,0 mm.
