Ichneumon luteator FABRICIUS 1798 - Supplementum entomologiae systematicae: 222, ♀, Ƌ. Ischnojoppa luteator: HEINRICH 1934 - Mitt. Zool. Mus. Berlin 20 (1): 237, ♀, Ƌ. F e m a l e

F l a g e l l u m: Lanceolate, with 34 segments, most broad segments slightly more than three times broader than length, with white semiannulus dorsally on segments 8-12, rufous up to middle; first segment long, 4,8 times longer than the width at apex. Flagellum

relatively short, 1,2 times shorter than the length of front wing and 2,1 times of body length.

H e a d: Head contour from front narrowed downwards, with almost equal width and height; genae from front long, 0,7 height of eye; from above transversal, 1,5 times wider than length. Vertex from lateral gradually slanting down to occipital carina; temples very long, approximately equal to longitudinal diameter of an eye at the middle, slightly roundly narrowed backwards, from side broadened toward mandible base; occipital carina from above deeply roundly impressed, but far not reach level of eyes and hind ocelli, sharp all round, meeting with hypostomal carina on mandible base; malar space 2,3 times longer than the mandible base width; mandibles broad, with long large teeth situated in the same plane and separated by wide gape, sharply curved at the middle; clypeus with almost straight (slightly rounded front margin), forming with face single surface, without traces of sutures and impressions; clypeal fovea not impressed (but clearly visible through cuticula); antennal cavities moderately deep, laterally above antennal fossae with tubercles, without trace of tooth between antennal fossae; ocelli small, cross diameter of lateral ocellus some times less than distance from ocellus to eye, ocellar triangle elevated and clearly expressed. Surface of head with the exception of antennal cavities slightly superficially punctured.

T h o r a x: Collar of pronotum very long, from the front high leaf-shaped widened and slanting backwards, therefore transverse furrow very deep, interrupted in middle by keel with more weak carinae laterally, hind thin margin of front lamellae slightly impressed in middle, not reach epomiae; epomiae very sharp, thin, high elevated; pronotal ridge not thickened; pronotal base uniformly and sharply slanted backwards; only upper lateral part of pronotum densely punctured. Mesonotum moderately convex of equal length and breadth; notauli only just marked at base; surface very densely punctured, to wrinkled on lateral lobes, opaque; prepectus strongly impressed behind front coxae; subalarum low, but sharp; speculum smooth, shining, without of traces of punctures; mesopleural fovea moderately impressed; sternauli completely absent; ventral part of mesothorax with strong longitudinal impression broadened backwards; lower part of mesopleurae roughly wrinkly-punctured, with very slight shine; scutellum strongly convex, sharply carinated up to apex, its horizontal part punctured by big punctures (punctures much wider than interspace between them), vertical part wrinkled. Hind margin of metanotum with triangular projections. Propodeum from lateral roundly and gradually slanting backwards, without distinct break, horizontal part some longer than area posteromedia in middle; all carinae of propodeum, with exception of carinae, limiting basal area and slightly expressed hind branches of lateral carinae, distinct; basal area slightly impressed; area superomedia long, hexagonal, narrow, from costulae sharply narrowed backwards; spiracles long. Surface of propodeum cellular-wrinkled, without microsculpture.

L e g s: Slender; claws smooth, slightly curved.

W i n g s: Areolet pentagonal, narrow in front, asymmetrical, external vein of base longer than internal and external vein of apex shorter than internal; stigma narrow; radius sinuous; nervulus very slightly postfurcal, almost interstitial; ramulus only just marked; all veins of hind wing distinct; veins colored as a body; membrane of wing slightly-yellowish. Length of front wing 1,2 times longer than length of flagellum and 1,7 shorter than body length.

A b d o m e n: Long, narrow with strong constrictions between segments, second tergite longer than width at apex, sheath of ovipositor protrude almost on length of sixth tergite, seventh tergite from above only just visible; abdomen sharply oxypygous. Petiolus of first tergite narrow, gradually broadened to postpetiolus, from lateral without sharp break; lateral and dorsal carinae not developed; distance between spiracles slightly more than distance from spiracles to apex; middle field of postpetiolus very slightly elevated (differentiated); middle field shagreen, lateral fields punctured by big superficial punctures. Gastrocoeli very deep, sharp, oblique; thyridia distinct, breadth of thyridia equal to interval between them; lunulae absent; interval between thyridia with sharp longitudinal wrinkles, middle part of tergite wrinkled up to apex, lateral parts very densely punctured (intervals narrower than punctures); third tergite with similar sculpture, forth densely punctured, fifth and sixth practically smooth. All sternites with longitudinal fold.

C o l o r a t i o n: Main color of body, including veins of wings, ferruginous; black: apices of hind femora and tibiae, tergites 5-7, segments of tarsi darkened; dorsal strip on segments 8-13 of flagellum and dorsal spot on tergite 7 white.

S i z e: Body length: 14,5; flagellum: 7,0; front wing: 8,5 mm.
