Hepiopelmus eudoxius WESMAEL 1844 - Nouv. mém. acad. sc. Bruxelles 18: 142, Ƌ. Heresiarches eudoxius WESMAEL 1859 - Mém. cour. sc. Belgique 8: 93, ♀, Ƌ. F e m a l e

F l a g e l l u m: Slender, long, bristle-shaped, with 30 segments, and with white annulus on segments 7-12(13), beyond white annulus slightly widened and flattened ventrally, most segments beyond white annulus transverse from lateral; first segment slender, 3,3 times longer than the width at apex. Flagellum 1,2 times shorter than the front wing and 1,5 times shorter than body length.

H e a d: Head contour from front roundish, 1,2 times wider than height, strongly narrowed downwards, with large eyes and short genae, genae from front 5,6 times shorter than height of eye; head from above strongly transversal, 1,7 times wider than length. Vertex from lateral gradually sloping behind ocelli to occipital carina; temples short, 1,5 times shorter than longitudinal diameter of an eye at the middle, from side parallel to hind margin of an eye, behind eyes from above sharply roundly narrowed; occipital carina not high, but distinct all round, from above strongly and roundly impressed, but far not reach level of eyes; hypostomal carina not visible from lateral, meeting with occipital carina almost on mandible base; malar space equal 0,7 mandible base width; mandibles sickleshaped, slender, lower tooth far moved inside and practically not visible from front; clypeus flat, slightly impressed relatively face, approximately 3 times wider than height, only just separated from middle field of face, with straight front margin and roundly oblique lateral corners; clypeal foveae small, but sharp; labrum narrow, triangular; middle field of face slightly differentiated; antennal cavities slightly impressed, reach borders of eyes and not reach front ocellus level, laterally above antennal fossae with tubercles and only just visible tubercle between antennal fossae; margins of antennal fossae high elevated above face surface; ocelli of normal size, diameter of lateral ocellus 1,4 times less than distance from ocellus to eye; ocellar triangle not elevated. Surface of clypeus and face with sparse superficial punctures, slightly shagreen between punctures, other part of head polished.

T h o r a x: Collar of pronotum long with straight front margin (from above); transverse furrow of pronotum broad, not interrupted by keel; epomiae sharp; pronotal base gradually curved, almost straight, with acute apex; pronotal ridge not thickened. Mesonotum moderately convex, of equal length and breadth; notauli completely absent; surface of mesonotum densely punctured, front part of middle lobe shagreen, lateral lobes with coriaceous sculpture between punctures, mesonotum slightly shining; axillary tongue not developed; subalarum high, thin, but not sharpened; area of speculum and considerable surface around it not sculptured, smooth, polished; area of mesopleural fovea broadly, but moderately impressed; mesopleural suture straight, interrupted by strong transversal ribs; sternauli practically absent, only at base in form of broad slight impression; upper half of mesopleurae with sparse shallow punctures, polished, lower half densely punctured to wrinkled, with slight microsculpture; scutellum practically not elevated, flat, uniformly sloping to postscutellum, only just carinated up to middle, its horizontal part polished with sparse, scattered punctures. Hind margin of metanotum with sharp triangle projections opposite lateral longitudinal carinae. Propodeum from lateral uniformly sloping from base to apex, without dividing on horizontal and vertical parts; fields reduced: area dentipara and area posteroexterna completely merged, area superomedia merged with area basalis and area superoexterna, third pleural area (apical pleural area) extremely sharply reduced, as result apices of areae dentiparae especially close approach to hind coxae; coxal and metapleural carinae sharp; spiracles long, slitshaped. Central part of propodeum up to apical transverse carina not sculptured, polished, other surface punctured, without microsculpture, shining.

L e g s: Thin and slender; claws long, smooth, curved slight; hind coxae of female without scopa.

W i n g s: Areolet pentagonal, asymmetrical, external vein of base longer than internal аnd external vein of apex shorter than internal; stigma broad, dark, radial cell broad and short, radius almost straight; nervulus slightly postfurcal; ramulus only just marked; all veins of front and hind wing pigmented; membrane of wing hyaline. Length of front wing 1,2 times shorter than body length.

A b d o m e n: Abdomen from above long, fusiform, seventh tergite sharpened, long, ovipositor distinctly protrude behind apex; abdomen oxypygous. First tergite from lateral practically straight; from above with very narrow petiolus at base; from lateral smooth, without traces of lateral carinae and any sculpture; from above petiolus gradually broadened to postpetiolus; distance between spiracles many more than distance from spiracles to hind margin of tergite; middle field practically not expressed and not limited by dorsal carinae; postpetiolus polished. Gastrocoeli deep, triangle, but small; thyridia distinct, occupy 0,5 of apex of gastrocoeli; lunulae small, but distinct; middle part of second tergite with sharp longitudinal wrinkles, other surface with dense punctures; third tergite with dense superficial punctures, other tergites smooth, shining. Hypopygium compressed from sides.

C o l o r a t i o n: Body with reach white pattern: face, with exception of narrow middle stripe, frontal and external orbits broadly, front and hind margins of pronotum, subalarum and spots on mesopleurae, scutellum and postscutellum, with exception of middle, spots at hind corners of propodeum, spots at corners of tergites 1-3 and apical stripes on tergites 5-6 and 7th completely. Legs red.

S i z e: Body length: 8,2; front wing: 6,8; flagellum: 5,5 mm.

M a l e

Similar by morphology and coloration to female. Flagellum of males without white annulus and with sharp moderately narrow tyloides on segments (8)9-16(17). Legs more strong.
