Description. Female. Body length: 1.85 mm (n=1).

Antenna color: antennal A1–A5 honey yellow, remainder of antenna dark brown. Body color: mostly honey yellow except posterior ¼ of mesoscutum, metasomal horn on T1 and T2–T7 dark brown. Coxae color: honey yellow. Leg color (excluding the coxae): honey yellow. Fore wing color: basal 1/3 and area at 2/5 hyaline, area below stigma infuscate as well as area beyond basal 1/3.

Head shape in lateral view: broad, short. Sculpture of antennal scrobe: smooth. Shape of torular triangle: not bulging, flat. Development of central keel on frons: completely absent. Sculpture of frons: largely smooth, with sparse setigerous punctulae. Sculpture of malar space: with fan-like striae extending onto antennal scrobe. Medial surface of vertex: flat to weakly convex (normal). Size of lateral ocellus: small (as in C. bouceki ). Distance between lateral ocellus and occipital carina:> 1.5x maximum ocellar width. Length of OOL: ≤1/3 width of ocellus. Sculpture of vertex: largely smooth, with sparse, setigerous punctulae. Surface of occiput: evenly concave (normal). Sculpture of occipital carina: strongly crenulate throughout. Proximity of occipital carina to orbital carina: well separated by distance at least 2x width of occipital carina. Shape of occipital carina: strongly sinuate medially, M-shaped. Sculpture of occiput: with sinuate, curved, longitudinal sculpture.

Sculpture of pronotal cervical area: transversely costate. Sculpture of pronotal lateral area: longitudinally costate. Netrion: absent, obscured by longitudinal sculpture on lateral pronotum. Notauli: present, simple. Width of notauli: narrow. Length of notauli: approximately 0.5x length of mesoscutum. Sculpture of mesoscutum: largely smooth, with sparse, setigerous punctures. Sculpture of mesoscutellum: smooth, foveae of submarginal sulcus subequal in size. Mesoscutellum shape: flat, conspicuously wider than long. Sculpture of lateral propodeum: densely, transversely costate. Shape of propodeal anterior spines: short, narrow, apex rounded. Sculpture of propodeum between anterior spines: with strong, oblique ridges laterally. Sculpture of ventral mesepisternum: largely smooth, with sparse, setigerous punctulae. Density of longitudinal costae on dorsal mesepisternum: sparse. Thickness of longitudinal costae on dorsal mesepisternum: thin. Length of longitudinal costae on dorsal mesepisternum: reaching to meso-metapleural suture. Sculpture of mesopleural femoral depression: smooth. Sculpture of metapleuron: with weak to well-defined longitudinal costae throughout.

Shape of wings: very convex in lateral view, with a conspicuous constriction at 2/5 of its length.

Shape of horn on T1 (in posterior view): narrow and short. Lateral carinae on posterior part of horn: absent. Sculpture of upper portion of T1 horn: smooth. Sculpture of posterior portion of T1 horn: with welldefined longitudinal carinae. Lateral carinae on T2: absent. Sculpture of T2: largely finely costate, costae longer near midline, posterior margin smooth, lateral margin with setigerous punctulae. Sculpture of T3: anterior 1/4 densely, weakly coriaceous, posterior 1/4 smooth, otherwise with fine, dense costae. Sculpture of S3–S6: with broad, well-developed costae throughout.

Male. Unknown.

Diagnosis. This species can be easily identified from all other species by the very conspicuously bent down and M shaped mid-dorsal area of the occipital carina, the presence of notauli, and having a flat mesoscutellum.
