Platylabus insulindicus HEINRICH 1934 - Mitt. Zool. Mus. Berlin 20: 244, ♀.

Cratolabus insulindicus HEINRICH 1974 - Ann. Zool. Wars. 32 (8): 162, comb. n. F e m a l e

F l a g e l l u m: Long and slender, bristle-shaped, slightly widened and flattened ventrally beyond middle, gradually attenuated toward apex, with white annulus on segments (7)-12(13); basal segments strongly elongated, first segment 3,9 times longer than width at apex. Flagellum longer than front wing and some shorter than body length.

H e a d: Head contour from front narrowed downwards, 1,3 times wider than height; genae from front sinuously narrowed downwards, rather long, 4,8 times shorter than height of eye; head contour from above transversal, 1,9 times wider than length. Vertex from lateral, obliquely and straightly abrupt just behind hind ocelli; temples (from above) sharply almost straightly narrowed behind eyes, from side 1,3 times shorter than longitudinal diameter of eye in middle, slightly widened downwards; occipital carina high, from above slightly almost angularly impressed to ocelli, far not reach level of eyes and hind ocelli; occipital carina meeting with hypostomal carina far from mandible base; length of genae approximately equal to mandible base width; mandibles sharply narrowed behind base, lower tooth moved inside; second segment of maxillary palps extraordinary strongly widened; clypeus strongly convex, 1,5 times wider than length, slightly impressed at apex (slightly concave apically), distinctly separated from face; clypeal foveae small, but deep; labrum broad, rather long, smoothly triangle (roundish); middle field of face almost not elevated above lateral fields, narrow; antennal cavities slightly impressed, laterally reach borders of eyes and far not reach front ocellus level, without lateral tubercles and atrophied interantennal tubercle; ocelli of normal size, diameter of lateral ocellus 1,4 times less than distance from ocellus to eye. Head surface shining with superficial punctures, without microsculpture; frons shining, not punctured.

T h o r a x: Collar of pronotum moderately short, transverse furrow shallow. Mesonotum moderately convex, some longer than width, notauli marked only at base; surface of mesonotum densely punctured, shining between punctures, without microsculpture; subalarum narrow, but not sharpened; speculum shining, punctured (intervals wider than diameter of the punctures); mesopleural fovea moderately and broadly impressed; sternauli distinct up to middle of mesopleurae; mesopleurae densely superficially-punctured, shining; scutellum moderately elevated, rounded in profile, laterally carinated up to apex, its surface with sparse superficial punctures. Hind margin of metanotum with triangle projections opposite lateral longitudinal carinae. Horizontal part of propodeum equal to length of area posteromedia in middle; all carinae of propodeum developed, sharp; basal area rather long and deep, area superomedia 1,3 times longer than width, hexagonal, slightly narrowed backwards, costulae approximately in middle; areae dentiparae with teeth curved upwards; spiracles narrow, elongated 2-2,5 times longer than width, of moderate size (length of spiracles equal 0,5 breadth of field at place of spiracle). Horizontal part of propodeum shining with irregular wrinkles, metapleurae densely uniformly punctured, shining.

L e g s: First segment of hind tarsus from lateral slightly curved; claws long gradually and strongly curved.

W i n g s: Areolet quadrangular, roundly pointed in front, asymmetrical (external vein of base longer than internal, and external vein of apex shorter than internal); stigma narrow, dark; radius slightly sinuous, long; radial cell long narrow; nervulus interstitial; ramulus distinct; membrane of wing hyaline, veins dark. Front wing only 1,2 times shorter than body length.

A b d o m e n:Fromabove broadly-oval, flattened; apical tergites not hidden and visible from above, ovipositor slightly protrude; second tergite transverse. Petiolus distinctly wider than height, from above gradually broadened to postpetiolus; first tergite from lateral without sharp transform to postpetiolus, with developed lateral carinae, middle field of postpetiolus slightly expressed, only just marked; distance between spiracles more than distance from spiracles to apex; surface of postpetiolus very slightly wrinkled, shining. Gastrocoeli deeply impressed, triangle; thyridia distinct, closed to base of tergite, equal by breadth to interval between them; interval punctured; lunulae distinct, of moderate size; tergites 2-3 densely punctured, intervals narrower than diameter of punctures, with very slight microsculpture, shining, forth tergite with very sparse shallow punctures, other tergites only slightly shagreen. Hypopygium sharpened with longitudinal fold, compressed from sides.

C o l o r a t i o n: Body with reach yellow-white pattern: genae, clypeus, face, with exception of narrow stripes on middle field, frontal orbits, stripes on pronotum, subalarum, spots on mesopleurae, scutellum and postscutellum, upper parts of metathorax (carinal triangle), propodeum apically, apical bands on all tergites of abdomen, sixth and seventh from above completely, front and middle coxae richly, hind with spot, trochanters I of front and middle legs completely and hind with spot.

S i z e: Body length: 9,3; front wing: 8,0 mm.
