Metanotum and propodeum dark brown with greenish-blue metallic luster; propodeum with a patch of white hair-like setae mesad to spiracle and callar region setose lateral to spiracle ( Fig. 27 View FIGURES 21‒29 ). Gaster elongate-lanceolate, brown with metallic luster ( Fig. 28 View FIGURES 21‒29 ); apex of syntergum dark brown, ovipositor sheath dark brown with apex brown ( Fig. 28 View FIGURES 21‒29 ).

Head in frontal view ( Fig. 23 View FIGURES 21‒29 ) 1.22× wider than high; in dorsal view ( Fig. 25 View FIGURES 21‒29 ) width 1.63× length, with interocular distance 0.17× head width and less than width of eye; in lateral view ( Fig. 24 View FIGURES 21‒29 ) with face convex, 1.40× higher than long. Eye height 1.0× eye width in lateral view ( Fig. 24 View FIGURES 21‒29 ); distance between eyes below 4.67× distance between eyes above ( Fig. 23 View FIGURES 21‒29 ); malar space 0.49× eye height ( Fig. 24 View FIGURES 21‒29 ); distance between toruli greater than distance between torulus and clypeal margin, and greater than distance between torulus and orbit. OOL: POL: LOL: MPOD = 1: 3.7: 6.5: 4.5. Vertex coriaceous around ocelli and imbricate posteriorly ( Fig. 25 View FIGURES 21‒29 ); lower face finely reticulaterugose ( Fig. 23 View FIGURES 21‒29 ); gena longitudinally reticulate ( Fig. 24 View FIGURES 21‒29 ); parascrobal region narrow; scrobal depression reticulate and transversely imbricate; interantennal region transversely reticulate ( Fig. 23 View FIGURES 21‒29 ). Scrobal depression deep, separated from anterior ocellus by distance equal to diameter of anterior ocellus. Lower orbit above level of ventral margin of torulus. Antenna with scape normal, not expanded ( Fig. 24 View FIGURES 21‒29 ); relative length (width) of scape = 40(8); pedicel 13(5); 1 st to 8 th funiculars: 4(5), 16(6), 18(7), 15(9), 12(10), 9(11), 8(12), 7.5(12); clava 23(13).

Pronotum in dorsal view divided medially, subtriangular, reticulate ( Fig. 22 View FIGURES 21‒29 ). Mesoscutum almost flat but slightly convex anteriorly, lateral lobe carinate posteriorly ( Fig. 22 View FIGURES 21‒29 ). Scutellar-axillar complex flat, longitudinally, coarsely reticulate, with dark brown setae; scutellum 1.32× longer than broad ( Fig. 22 View FIGURES 21‒29 ). Mesopectus meshlike reticulate, acropleuron with very fine longitudinally aligned coriaceous sculpture ( Fig. 21 View FIGURES 21‒29 ). Fore wing extended near apex of gaster, with SMV: MV: PMV: STV = 25: 29: 16: 9. Mesotibial spur shorter than basitarsus; mesotarsus with row of pegs on either side of basal four tarsomeres ( Fig. 21 View FIGURES 21‒29 ). Hind leg with basitarsus as long as following two tarsomeres combined ( Fig. 29 View FIGURES 21‒29 ). Propodeum with anterior margin broadly U-shaped ( Figs 27 View FIGURES 21‒29 , 46 View FIGURES 44‒47 , indicated by arrows); plical region narrow, reticulate; callar region smooth and shiny ( Figs 27 View FIGURES 21‒29 , 46 View FIGURES 44‒47 ).

Gaster longer than mesosoma, elongate-lanceolate ( Fig. 28 View FIGURES 21‒29 ); Gt 1 and Gt 2 V-like emarginate, Gt 3 and Gt 4 broadly U-like emarginate, Gt 5 shallowly emarginate, Gt 6 convex, syntergum tapered to apex; ovipositor sheath exserted for distance equal to length of basal metatarsomere ( Fig. 42 View FIGURES 40‒43 ).

Variation. The paratype is 4.6 mm in length; scrobal depression separated from anterior ocellus by a distance about 0.7× diameter of anterior ocellus; distance between posterior ocellus and compound eye is very narrow, OOL: POL: LOL: MPOD = 1: 7: 13: 12. The hyaline spot of the fore wing of the paratype is not as white as for the holotype, but more light brown, and the mesoscutum is darker green with less metallic luster.

Distribution. CHINA: Zhejiang.

Remarks. The fore wing color pattern resembles that of Z. stom   ( Fig. 51 View FIGURES 48‒52 ), but the hyaline spot of Z. stom   is triangular.

Etymology. The species name is from the Latin word “ nivalis ”, which means snowy, and the Latin word “ nota ”, which means a mark, in reference to the white spot behind the marginal vein.
