Description.

Female. Body length 4.1-5.8 mm, fore wing length 4.3-6.2 mm. Transverse diameter of eye (dorsal and lateral view) 1.1-1.4 × longer than temple. POL 1.1-1.3 × Od. OOL 2.5-2.8 × Od. OOL 1.9-2.4 × POL. Face width 1.2-1.5 × combined height of face and clypeus, 1.9-2.0 × width of hypoclypeal depression. Longitudinal diameter of eye 2.2-2.7 × longer than malar space (anterior view). Malar suture absent. Scape (lateral view) as long dorsally as ventrally, concave laterally. Mesosoma 1.5-1.7 × longer than its maximum height. Notauli impressed anteriorly, shallow and not united posteriorly. Fore wing vein 1-R1 1.4-1.8 × longer than pterostigma. Marginal cell 5.5-6.6 × longer than distance from its apex to apex of wing. Vein 3-SR 3.5-3.9 × vein r. Vein 3-SR 0.50-0.70 × vein SR1. Vein 3-SR 1.8-2.3 × vein 2-SR. Vein 1-SR+M weakly curved forward proximately. Wing membrane evenly setose in base of hind wing. Hind femur 3.2-3.4 × longer than wide. Claws with moderately large rounded basal lobe. Median length of first tergite 1.0-1.2 × its apical width. Dorsal carinae of first metasomal tergite absent; dorsolateral carinae weakly separated. Second metasomal tergite medially 1.25-1.30 × as long as third tergite; with long parallel sublateral carinae and anterolateral, posteriorly diverging sublateral crenulated grooves; basal width of second tergite 1.4-1.6 × its median length. Anterolateral areas of second metasomal tergite elongate-triangulate, strongly separated by crenulate furrows and sharp crenulate margins; median area of tergite strongly elevated, triangle, large and wide, rounded on sides, separated by crenulate furrows and complete sharp margin. Apical margins of third to sixth tergites without transverse subapical grooves. Ovipositor sheath about 1.5 × longer than hind tibia, 0.41-0.46 × as long as fore wing. Apex of ovipositor without distinct nodus, acute; with weak or more or less developed ventral serration. Body entirely smooth, only first metasomal tergite sometimes foveate-rugose apicomedially. Body mostly brownish black; head, prothorax (often also mesoscutum), tegulae and pattern on fore leg reddish yellow; maxillary palps yellow; wing membrane brownish darkened; pterostigma and wing veins brown; membranous areas of metasomal sterna pale yellow.

Diagnosis.

Cyanopterus tricolor differs from similar species ( C. hinoemataensis , C. kusarensis , and C. praecinctus ) by the relatively long ovipositor (in related species it is 0.85-1.00 × and 0.2-0.3 × as long as hind tibia and fore wing, respectively) and absence of transverse subapical grooves on third-fifth metasomal tergites.
