Material.

South Korea - Gangwon-do • 1 female; Hongcheon-gun, [12] Duchon-myeon; 11 Oct. 1995; J.Y. Choi leg.; NIBR 524 .

Distribution.

China ( Li et al. 2020c): Hubei, Zhejiang. South Korea (new record).

Description.

Character states from Li et al. (2020c) are given in parentheses. Female. Body length 4.7 mm (6.4-6.6 mm), fore wing length 4.8 mm. Transverse diameter of eye (dorsal view) 1.6 × (2.1 ×) and (lateral view) 1.8 × longer than temple. POL 1.4 × Od (1 ×); OOL 2.5 × Od (2 ×); OOL 1.8 × POL (2 ×). Face width 1.2 × (1.4 ×) combined height of face and clypeus, 2.0 × width of hypoclypeal depression. Longitudinal diameter of eye 3.1 × longer than malar space (anterior view). Malar suture absent. Scape (lateral view) 1.6 × longer than maximum wide, longer ventrally, than dorsally, concave laterally. Mesosoma 1.6 × (1.8 ×) longer than its maximum height. Notauli deep anteriorly, absent and not united posteriorly. Fore wing vein 1-R1 1.5 × longer than pterostigma. Vein 3-SR 3.2 × (3.3 ×) vein r, 0.63 × (0.68 ×) vein SR1, 2.1 × vein 2-SR. Vein 1-SR+M curved forward proximately. Wing membrane evenly setose in base of hind wing. Hind femur 3.7 × (3.8 ×) longer than wide. Claws with moderate large rounded basal lobe. Median length of first metasomal tergite as large as its apical width (1.1 × its apical width). Dorsal carinae of first metasomal tergite incomplete, strongly curved towards apex; dorsolateral carinae developed. Second metasomal tergite medially 1.3 × longer than third tergite; basal width of second tergite 1.4 × larger than its median length; with long weakly converging sublateral carinae; without sublateral posteriorly diverging grooves. Anterolateral areas of second metasomal tergite elongate-triangulate, very long, smooth, with sharp crenulate margins; median area of tergite strongly elevated, short and wide, transverse-triangle, with long narrow “tail” posteriorly; separated by sharp crenulate margin. Transverse subapical grooves absent on third tergite, incomplete on fourth tergite, and complete on fifth tergite, crenulate. Ovipositor sheath 0.95 × as long as hind tibia, 0.3 × (0.2 ×) as long as fore wing. Apex of ovipositor with developed nodus and ventral serration. Body mostly smooth; first metasomal tergite laterally weakly rugulose, its median area apically foveate-rugose; second tergite medially rugose, laterally smooth. Coloration mostly as in Cyanopterus tricolor (Ivanov), but tegula and fore legs entirely yellow and mesoscutum and scutellum rusty.

Diagnosis.

The species is very similar to Campyloneurus bohayicus (Belokobylskij, 2000), their differences are listed below.

1	Scape about 2 × longer than maximum wide ( Samartsev 2019: fig. 24). Head black. Apex of ovipositor without nodus and ventral serration, simple and acute (ibid: fig. 24). Face more or less granulate (ibid: fig. 5). Hind wing membrane proximally with sparse setosity near vein cu-a (ibid: fig. 25). Anterolateral areas of second metasomal tergite elongate-triangulate, but less long (ibid: fig. 14)	Campyloneurus bohayicus (Belokobylskij)
-	Scape about 1.5 × longer than maximum wide (Fig. 96 ; Li et al. 2020c: fig. 16K). Head rusty. Apex of ovipositor with well-developed nodus and ventral serration (Fig. 97 ; Li et al. 2020c: fig. 16i). Face smooth (Fig. 94 ; Li et al. 2020c: 16g). Hind wing membrane proximally evenly setose (Fig. 93 ; Li et al. 2020c: 16b). Anterolateral areas of second metasomal tergite elongate-triangulate, very long (Fig. 94 ; Li et al. 2020c: fig. 16e)	Campyloneurus pachypus Li, van Achterberg & Chen
