Ceratojoppa cornuta CAMERON (Plate 5)

Ceratojoppa cornuta CAMERON 1905 - Ztschr. System. Hym. Dipt. 5: 346, Ƌ. Ceratojoppa cornuta cornuta HEINRICH 1967 - Ichn. Stenop. of Africa 1: 203-204, ♀, Ƌ. F e m a l e

F l a g e l l u m: Slender, bristle-shaped, with 40 segments and white annulus on 9-15 segments, slightly widened and flattened ventrally beyond white annulus, first segment long and slender, 6 times longer than the width at apex, segments beyond white annulus transversal, segment 35 square from lateral, apical segments elongated. Female flagellum almost equal by length to front wing and 1,6 times shorter than body length.

H e a d: Head contour from front roundly narrowed downwards, only just transverse, only 1,2 times wider than height; genae from front moderately long, 0,3 height of eye; head contour from above stout, transversal, 1,6 times wider than length. Vertex from lateral vertically abrupt to occipital carina just after the ocelli; temples long, in most broad part 1,4 times longer than longitudinal diameter of an eye at the middle, from above roundly narrowed behind eyes, temples from side strongly broadened toward mandible base; occipital carina from above angularly impressed but far not reach level of eyes and hind ocelli, very high, broadened almost lamelliform in top half, not reaching base of mandible and not meeting with hypostomal carina (reduced in lower fourth); malar space approximately equal to mandible base width; mandibles very broad, sharply curved at the middle almost at right angle, practically not narrowed toward apex, with wide gape between large teeth situated in the same plane, upper tooth longer and narrower than lower; mandibles strongly bordered; clypeus transverse, two times wider than height, with oblique lateral sides and rounded corners, not separated from face (practically confluent with middle field of face), with straight front margin; clypeal foveae deep; labrum equal by breadth to front border of clypeus, but very short, only just protrude from under clypeus; middle field of face very slightly elevated above lateral fields only at upper part; antennal cavities deeply impressed, reach front ocellus level and borders of eyes, laterally above antennal fossae with only just visible tubercles and with distinct tubercle between antennal fossae; frons with five longitudinal carinae, short middle carina under front ocellus only just visible, two more long from projecting corners of internal part of antennal fossae and two vertical carinae on lateral sides from level of front ocellus toward middle of antennal fossae; lower part of converging frontal carinae with strong horn- shaped projections triangular from side; ocelli of moderate size, diameter of lateral ocellus 1,5 times less than distance from ocellus to eye; ocellar triangle high elevated and well-defined; head surface not sculpturated, smooth, polished.

T h o r a x: Collar of pronotum moderately long, from above with straight front margin; transverse furrow shallow; pronotal ridge not swollen; epomiae distinct; lower angle of pronotum very sharp. Mesonotum dorsally flattened; middle lobe elevated, with flattened front surface, lateral lobes of mesonotum strongly lowered, theirs external margins form elevated ribs, directed mainly to apex; notauli sharp, forming all round broad shallow furrows, roughly and irregularly transversally-wrinkled, converging towards scuto-scutellar groove; mesonotum at apical corners between tegula and scuto-scutellar groove with roundish blade form projections above axillary tongues; surface of middle lobe punctured, without microsculpture, lateral lobes smooth, polished; prepectus above front coxae with two longitudinal ribs; subalarum thin, sharp; area of mesopleural fovea only just impressed; mesopleural suture without bend toward mesopleural fovea; sternauli absent; surface of mesopleurae not sculptured, polished; scutellum high elevated above postscutellum, laterally and apically carinated by very high carina, its dorsal surface flat with sparse punctures, shining. Hind margin of metanotum with sharp triangle projections opposite lateral longitudinal carinae. Propodeum from lateral gradually and roundly slanted backwards, horizontal part of propodeum 1,4 times longer than area posteromedia in middle; carinae of horizontal part of propodeum atrophied in considerably extent; area basalis merged with first lateral field and limited from behind only by cellular sculpture; from carinae of horizontal part developed only slightly expressed apical transverse carina and front branches of lateral longitudinal carinae, limiting areae dentiparae and external parts of costulae; coxal carina marked only at base; spiracles of propodeum long, slitshaped; front half of horizontal part up to costulae not sculptured, polished, posterior half presented by cellular sculpture (Morphology of propodeum somewhat remind of ichneumon flies of ophionoid complex).

L e g s: Long, thin, femora very thin with long and sparse pubescence, coxae small, hind coxae without scopa; claws smooth.

W i n g s: Areolet quadrangular, slightly petiolate, slightly asymmetrical (intercubital veins of equal length, but internal vein of apex shorter than external); stigma narrow, light; radius strongly sinuous; nervulus slightly postfurcal; ramulus distinct, but weak; membrane of wing hyaline; all veins of hind wing distinct; veins of both wings moderately darkened. Length of front wing more than 1,5 shorter than body length.

A b d o m e n Of females from above slender, long; second tergite almost 1,5 times longer than width at apex; abdomen oxypygous with projecting almost on length of seventh tergite sheath of ovipositor. First tergite from lateral without sharp bend, gradually convex, almost straight, without dorsal and lateral carinae; petiolus of first tergite from above gradually and slightly broadened to postpetiolus; postpetiolus without expressed middle field; distance between spiracles equal to distance from spiracles to apex; postpetiolus wrinkly-punctured. Gastrocoeli form long longitudinal lateral impression, with large transverse thyridia, that 1,4 times more than interval between them; lunulae absent, surface of second and third tergites densely punctured, semimatt, other tergites densely punctured, slightly shining, apical stripes of all tergites shining, without microsculpture. Hypopygium compressed from side.

C o l o r a t i o n: Main color of a body light-ferruginous, face, margins of frons

(broadly), most part of temples, coxae, mesopleurae, lateral parts of propodeum and apex of tergite 7 of abdomen (slightly) yellowish-white.

S i z e: Body length: 15,5; front wing: 9,5; flagellum: 10 mm.
