Eye height 1.03× eye width in lateral view ( Fig. 4 View FIGURES 1‒11 ); distance between eyes below 3.95× distance between eyes above ( Fig. 5 View FIGURES 1‒11 ); malar space 0.42× eye height ( Fig. 4 View FIGURES 1‒11 ); distance between toruli greater than distance between torulus and clypeal margin, and greater than distance between torulus and orbit.

Scutellar-axillar complex flat, coarsely longitudinally reticulate; scutellum 1.40× longer than broad ( Fig. 7 View FIGURES 1‒11 ). Mesopectus meshlike reticulate, acropleuron with very fine longitudinally aligned coriaceous sculpture. Fore wing extended near apex of gaster, with SMV: MV: PMV: STV = 25: 33: 17: 8. Middle leg with spur shorter than basitarsus ( Fig. 9 View FIGURES 1‒11 ); mesotarsus with row of pegs on either side of basal four tarsomeres. Hind leg with basitarsus as long as following two tarsomeres combined ( Fig. 8 View FIGURES 1‒11 ). Propodeum with anterior margin broadly V-shaped ( Figs 2 View FIGURES 1‒11 , 44 View FIGURES 44‒47 , indicated by arrows); plical region comparatively broad, coarsely reticulate; callar region smooth and shiny ( Figs 2 View FIGURES 1‒11 , 44 View FIGURES 44‒47 ).

Gaster longer than mesosoma ( Fig. 1 View FIGURES 1‒11 ), elongate-lanceolate ( Fig. 11 View FIGURES 1‒11 ); Gt 1 –Gt 3 deeply V-like emarginate, Gt 4 and Gt 5 slightly emarginate, Gt 6 convex, syntergum tapered to sharp apex ( Fig. 40 View FIGURES 40‒43 ); ovipositor sheath exserted for short distance, as long as 4/5 of basal metatarsomere.

Variation. The female paratype is 4.7 mm in length; scrobal depression separated from anterior ocellus by distance about 0.9× diameter of anterior ocellus.

Distribution. CHINA: Hainan.

Remarks. Females of this new species have a similar fore wing colour pattern ( Fig. 10 View FIGURES 1‒11 ) as those of Z. tubatius ( Fig. 34 View FIGURES 30‒39 ), Z. keralensis ( Fig. 48 View FIGURES 48‒52 ) and Z. mampadicus ( Fig. 52 View FIGURES 48‒52 ), but differ by the dorsal margin of the metatibia being white basally ( Fig. 8 View FIGURES 1‒11 ). Further, the tibial spur of Z. keralensis is yellow or pale yellow, Gt 3 is slightly emarginate and Gt 4 is evenly convex, whereas Z. candetibia has the mesotibial spur very dark brown to black, Gt 3 is deeply emarginate, and Gt 4 is slightly emarginate; the middle of the propodeum of Z. tubatius is very narrow ( Figs 36 View FIGURES 30‒39 , 47 View FIGURES 44‒47 ), whereas the middle of propodeum of Z. candetibia is broader ( Figs 2 View FIGURES 1‒11 , 44 View FIGURES 44‒47 ). The gaster of Z. mampadicus was described as about 1.8× longer than the mesosoma, whereas the gaster of Z. candetibia is only about 1.4× longer than the mesosoma.

Etymology. The species name is a combination of the Latin words “ candeo ” which means shining white, and “ tibia ”, in reference to the metatibia having a white margin basally.
