6. Cyclolabellus HEINRICH

Cyclolabellus HEINRICH 1974 - Ann. Zool. Warszawa 32: 145-146.

Type species: Cyclolabellus pertenuis HEINRICH.

D i s t r i b u t i o n: Oriental Region ( Burma). 1 species.

I n t r o d u c t i o n:

The genus is affined with Cyclolabus by small, almost circular spiracles of propodeum. In contrast to Cyclolabus propodeum is shortened, horizontal part approximately two times shorter than area posteromedia in the middle. Area superomedia is distinctly longer than width. Notauli not developed. Gastrocoeli are distinctly impressed, rather long, nearly quadrangular. Thyridia are slightly expressed, interval is some wider than breadth of thyridia.

M o r p h o l o g y:

F l a g e l l u m: Very long and slender, bristle-shaped, beyond middle not widened with very long basal segments, all segments longer than wide. Flagellum considerably longer than the front wing.

H e a d: Head contour from front roundish, genae from front short, strongly narrowed toward mandibles base; eyes very large. Temples behind eyes (from above) very short; occipital carina meeting with hypostomal carina almost on mandible base; mandibles slender, evenly narrowed behind base, lower tooth moved inside; clypeus moderately convex, transversal, with straight apical margin and rounded lateral corners; middle field of face only just elevated; antennal cavities small, slightly impressed with tooth between antennal fossae; ocellar triangle practically not elevated. Surface of face and clypeus densely and finely punctured, slightly shining.

T h o r a x: Transverse furrow of pronotum not interrupted by keel; pronotal ridge not thickened; pronotal base gradually uniformly curved. Mesonotum moderately convex, some wider than length, notauli only just marked in front third; surface of mesonotum very densely punctured; subalarum thin, not sharpened; sternauli slightly impressed in front third; scutellum convex, laterally carinated up to apex, gradually sloping to postscutellum. Hind margin of metanotum with very long bacilliform projections opposite lateral longitudinal carinae. Propodeum from lateral gradually slanting; length of horizontal part approximately two times shorter than area posteromedia in middle; carinae of propodeum developed, with exception of costulae and coxal carina; area dentipara with only just visible denticle at apex; spiracles small, circular, only just longer than width. Surface of propodeum very densely wrinkly-punctured, slightly shining.

L e g s: Quite long, moderately slender.

W i n g s: Areolet big, quadrangular (almost pentagonal with very narrow base), almost symmetrical; radius slightly sinuous, long; nervulus interstitial. Front wing some shorter than body length.

A b d o m e n Of females compressed dorso-ventrally. Petiolus flattened, from lateral with distinct, but gradual bend; laterally carinated; from above petiolus gradually broadened to postpetiolus; middle field of postpetiolus distinctly elevated, with slight rugosity. Gastrocoeli distinctly impressed, rather long, approximately quadrangular; thyridia slightly expressed; lunulae distinct, moderately large; tergites 2 and 3 delicate and rather densely punctured, distinctly shining.

C o l o r a t i o n: Head and thorax black, with rather reach, yellow-white pattern; most part of abdomen red, base and apex black, last tergite with white border at apex.
