Description. FEMALE. Length about 4.2–4.5 mm. Head with coppery-green metallic luster, vertex dark green (Figs 30, 32); setae of face, gena and occiput white, parascrobal region with one row of white setae (Fig. 30), setae of vertex black (Fig. 32). Maxillary and labial palpi black (Fig. 30). Antennal scape with yellowish-green metallic luster, pedicel and flagellum very dark brown to black (Fig. 33). Pronotum with coppery, purple and green metallic luster, setae dark brown (Fig. 35); mesoscutum with coppery-blue metallic luster, and with white hair-like setae (Fig. 35); prepectus and tegula brown; tegula with dark brown setae (Fig. 35); mesopectus dark bluish green, with long white setae arranged linearly along acropleural sulcus, extending to level of about middle of tegula; acropleuron black with dark blue and purple metallic lusters; scutellar-axillar complex black with dark green metallic luster, setae black (Fig. 36). Fore wing infuscate beyond level of parastigma and gradually lightened distally, but with hyaline cross-band behind apex of marginal vein with white setae (Fig. 34). 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); 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). Gaster elongate-lanceolate, dark purple with metallic luster; apex of syntergum and ovipositor sheath pale yellowish brown (Fig. 38).

Head in frontal view (Fig. 30) 1.34× wider than high; in dorsal view (Fig. 32) width 1.87× length, with interocular distance 0.20× head width and less than width of eye; in lateral view (Fig. 31) with face almost straight, 1.51× higher than long. Eye height 1.51× eye width in lateral view (Fig. 31); distance between eyes below 3.74× distance between eyes above (Fig. 30); malar space 0.49× eye height (Fig. 31); 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); lower face reticulate-rugose; gena longitudinally reticulate (Fig. 30); parascrobal region very narrow; scrobal depression reticulate and transversely imbricate; interantennal region transversely reticulate-imbricate (Fig. 30). 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); 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). Mesoscutum almost flat but slightly convex anteriorly, lateral lobe carinate posteriorly (Fig. 35). Scutellar-axillar complex flat, longitudinally, coarsely reticulate, with black setae; scutellum 1.24× longer than broad (Fig. 36). 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). Propodeum with anterior margin broadly convex (Figs 39, 47, indicated by arrows); plical region sublinear; callar region smooth and shiny (Figs 36, 39, 47).

Gaster longer than mesosoma, elongate-lanceolate (Figs 38, 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); ovipositor sheath exserted for very short distance, as long as 1/2 of basal metatarsomere (Fig. 38).

Distribution. CHINA: Guangdong, Hainan, Hong Kong.

Remarks. The dorsal margin of the metatibia of Z. tubatius females appears white (Fig. 37), but it is actually black (Figs 37, 60) 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). 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), 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.
