body
shape♀ 3mm [T15]. Body length 2.7 - 3.7 mm. [T2].
colorBlack. The body is completely rugulose, matte; The hairs on the body are relatively sparse and short, light-colored [T15].
head
shapeHead 2.5 times as wide as long, roundly narrowed behind eyes; temples equal to the width of the eye; the width of the base of the ocellar triangle is 1.5 times less [?] than the distance from it to the eye, the distance between the posterior ocelli is twice the ocellus diameter; longitudinal eye diameter 2.5 times transverse, 4 times longer than cheeks; face height half its width, 1.5 times its [?] height; palps short, slightly more than height of face [T15]. Head roundly narrowed behind eyes, wider than mesosoma, more than twice as wide as long. Length of temples equal to, or slightly less than transverse diameter of eye. Length of base of ocellar triangle 1.5 times OOL or subequal to it. POL 2–3 times diameter of ocellus. Longitudinal diameter of eye 2.5 times, or little more, exceeding transverse one, 3–4 times malar space. Width of face twice its height. Rostrum not developed. Length of maxillary palpus half height of face [T2][T14]. Malar space 0.4 times the longitudinal diameter of the eye [T14]. The head is wider than the mesosoma, roundly narrowed behind the eyes: its width is almost 2.5 times its length; the occiput is strongly carved; temples slightly shorter than the width of the eye; ocelli in an obtuse triangle, base of which is almost equal to the distance from it to the eye; the distance between the posterior ocelli is three times greater than the diameter of the ocellus; eyes relatively weakly narrowed downwards, their longitudinal diameter is slightly larger than twice the transverse and three times longer than the cheeks. The width of the clypeus is twice its height; the distance between tentorial pits is almost equal to the distance from them to the eye; [Ab2].
sculptureClypeus smooth, face and occiput without conspicuous transverse rugae [T15]. Face and vertex behind ocelli delicately transversely rugose; clypeus densely and finely punctate, shiny.
color
antenna
shape ♀Antenna slightly longer than the head and mesosoma, scapus much longer than the 3rd segment of the antenna; flagellum thin, filiform, segments of flagellum 3-4 times, at apex twice as long as wide [T15]. Antennae slightly longer than head and mesosoma combined; segments in basal part of flagellum 4 times as long as wide, those in its apical part nearly twice as long as wide [T2]. 12th antennal segment 3 times as long as wide [T9]. Third segment four times as long as broad [P4].
shape ♂Antennae 22-segmented [T2][T14]. Antennae longer than head and mesosoma, thin, filiform; 3rd antennal segment slightly shorter than the scapus, slightly longer than the 4th segment, three times as long as wide; segments of flagellum beyond middle slightly shortened towards apex [Ab2].
color
mesosoma
shapeThe mesosoma is one third longer than its height, the parapsidal grooves are indistinct. Propodeum with a weak transverse ridge and two lateral teeth [T15]. Length of mesosoma 1.3 times its height. Propodeum with weak transverse carina and moderately developed lateral teeth [T2][T14]. Notauli are weak. The propodeum is truncate posteriorly, with two teeth on the sides [Ab2].
sculptureScutellum densely and finely punctate, shiny [T2][T14].
color
legs
shape♀ Hind femur 4–5 times as long as wide [T2]. Length of hind tibia 6 times its apical width [T14]. Hind femora 4.0 - 4.2 times as long as wide; large spur of hind tibia slightly more than one third of 1st tarsus segment, 5th segment of hind tarsus equal to 3rd, shorter than 2nd [Ab2]. Hind femora 4.5 times as long as wide [T4].
sculpture
colorThe legs are brown. Fore and middle tibiae, apices of fore femora, main 2/3 of hind tibiae yellowish brown [T15]. Fore and middle femora apically, fore and middle tibiae, and also most part of hind tibia yellowish brown. Middle of hind tibiae usually brownish yellow [T2]. 1st segment of hind tarsus, except for apex, yellow [T9].
wings
shape1-R1 is 1.5 times as long as [shorter than?] the pterostigma; the radial vein departs at a short distance behind the middle of the pterostigma, r and 3-SR are approximately equal in length; 1-CU1 = 0.5 times 2-CU1 [T15]. 1-R1 0.6–0.9 times as long as pterostigma [T2]. 1-R1 is almost equal to the length of the pterostigma; 3-SR is 1.5 times shorter than r, 4.5-5 times shorter than SR1, 2.5 times shorter than 2-SR; 1-CU1 = 0.5 times 2-CU1 (Fig. 11) [Ab2, caucasicus]. 1-R1 distinctly (1.5 times) less wide than length of pterostigma [P4].
colorWings slightly darkened, pterostigma and veins in apical half of wing brown, veins in basal half of wing yellowish [T15]. Wings slightly infuscate [T2][T14]. Veins in the middle of wing, before 2nd submarginal cell, pale yellow [T9].
metasoma
shapeThe metasoma is equal to the length of the head and mesosoma, elongated-oval; metasomal carapace not bent posteriorly, its length 4 times its height at apex, 2.5 times its width in middle part [T15]. Metasoma oblong-oval, not bend apically [T2]. Metasoma slightly shorter than head and mesosoma, slightly oval, bent down from behind, its length 2.5 times its width, 3.5 times its height in apical third [Ab2]. Carapace more or less linearly narrowing in apical third [T9]. Metasoma without emargination at apex [T4]. ♂ metasomal length 2.0-2.1 its width [T14, key].
sculptureBase of the metasoma with longitudinal rugae [T15]. Base of metasoma with longitudinal rugae [T2].
color
♀ ovipositorThe ovipositor does not project beyond the apical metasoma [T15]. Ovipositor not projecting or projecting slightly beyond apex of metasoma [T2]. Ovipositor sheath very short, hardly projecting beyond carapace [P4].
♂ apertureAperture oval, occupying about half, but no more than half of width of metasoma [T2]. Aperture occupies 0.3 abdominal width [T14].

remarksClose to C. parcicornis H.-Sch., From which it differs in significantly more elongated eyes, short cheeks, thin antennae and hind femora [T15].
