Legs with femora and tibiae dark brown, protarsus brown, mesotarsus pale yellowish brown with rows of pegs and spur black, metatarsus pale yellowish brown ( Fig. 38 View FIGURES 30‒39 ); metatibia dark brown, with white hair-like setae and additionally densely setose with white setae along dorsal surface. Metanotum and propodeum black with dark green metallic luster; propodeum with a patch of white hair-like setae mesad to spiracle and callar region setose lateral to spiracle ( Fig. 39 View FIGURES 30‒39 ). Gaster elongate-lanceolate, dark purple with metallic luster; apex of syntergum and ovipositor sheath pale yellowish brown ( Fig. 38 View FIGURES 30‒39 ).

Head in frontal view ( Fig. 30 View FIGURES 30‒39 ) 1.34× wider than high; in dorsal view ( Fig. 32 View FIGURES 30‒39 ) width 1.87× length, with interocular distance 0.20× head width and less than width of eye; in lateral view ( Fig. 31 View FIGURES 30‒39 ) with face almost straight, 1.51× higher than long. Eye height 1.51× eye width in lateral view ( Fig. 31 View FIGURES 30‒39 ); distance between eyes below 3.74× distance between eyes above ( Fig. 30 View FIGURES 30‒39 ); malar space 0.49× eye height ( Fig. 31 View FIGURES 30‒39 ); distance between toruli greater than distance between torulus and clypeal margin, and greater than distance between torulus and orbit. OOL: POL: LOL: MPOD = 1: 6: 9: 11. Vertex coriaceous around ocelli, and transversely imbricate posteriorly ( Fig. 32 View FIGURES 30‒39 ); lower face reticulate-rugose; gena longitudinally reticulate ( Fig. 30 View FIGURES 30‒39 ); parascrobal region very narrow; scrobal depression reticulate and transversely imbricate; interantennal region transversely reticulate-imbricate ( Fig. 30 View FIGURES 30‒39 ). Scrobal depression deep, separated from anterior ocellus by distance equal to 0.63× diameter of anterior ocellus. Lower orbit above ventral margin of torulus. Antenna with scape foliaceously dilated ( Fig. 33 View FIGURES 30‒39 ); relative length (width) of scape = 40(16); pedicel 9(5); 1 st to 8 th funiculars: 5.5(5.5), 18(5), 18(6), 21(9), 15(10), 12(11), 10(11), 9(11); clava 25(12).

Pronotum in dorsal view divided medially, pentagonal, transversely imbricate ( Fig. 35 View FIGURES 30‒39 ). Mesoscutum almost flat but slightly convex anteriorly, lateral lobe carinate posteriorly ( Fig. 35 View FIGURES 30‒39 ). Scutellar-axillar complex flat, longitudinally, coarsely reticulate, with black setae; scutellum 1.24× longer than broad ( Fig. 36 View FIGURES 30‒39 ). Mesopectus meshlike reticulate, acropleuron with very fine longitudinally aligned coriaceous sculpture. Fore wing extended near apex of gaster, with SMV: MV: PMV: STV = 25: 31: 22: 8. Mesotibial spur shorter than basitarsus; mesotarsus with row of pegs on either side of basal four segments. Hind leg with basitarsus as long as following two tarsomeres combined ( Fig. 37 View FIGURES 30‒39 ). Propodeum with anterior margin broadly convex ( Figs 39 View FIGURES 30‒39 , 47 View FIGURES 44‒47 , indicated by arrows); plical region sublinear; callar region smooth and shiny ( Figs 36, 39 View FIGURES 30‒39 , 47 View FIGURES 44‒47 ).

Gaster longer than mesosoma, elongate-lanceolate ( Figs 38 View FIGURES 30‒39 , 43 View FIGURES 40‒43 ); Gt 1 and Gt 2 deeply V-like emarginate, Gt 3 broadly U-like emarginate, Gt 4 –Gt 6 shallowly emarginate, syntergum tapered to rounded apex ( Fig. 43 View FIGURES 40‒43 ); ovipositor sheath exserted for very short distance, as long as 1/2 of basal metatarsomere ( Fig. 38 View FIGURES 30‒39 ).

Distribution. CHINA: Guangdong, Hainan, Hong Kong.

Remarks. The dorsal margin of the metatibia of Z. tubatius   females appears white ( Fig. 37 View FIGURES 30‒39 ), but it is actually black ( Figs 37 View FIGURES 30‒39 , 60 View FIGURES 59‒63 ) except dorsally it is densely setose with white setae. The holotype is in very poor condition, with only the mesosoma, four legs and part of one fore wing remaining ( Figs 59–63 View FIGURES 59‒63 ). Actually, the head was missing already when Walker (1852) described the species. The middle of the propodeum of the holotype has a very narrow plical region ( Fig. 62 View FIGURES 59‒63 ), and the metatibia is densely setose dorsally as described above.

Gibson (2005), when transferring the species from Eupelmus   to Zaischnopsis   , changed the specific epithet to tubatia   . However, tubatius   is a noun in apposition as indicated by the use of a capital letter for the species epithet in the original description. According to ICZN Art. 31.2.1 the species name should remain unchanged.
