Diagnosis

Head with dorsal margin of scrobal depression separated from anterior ocellus by distance equal to 0.77 × diameter of anterior ocellus ( Fig. 4D View Fig ); OOL: POL: LOL: MPOD = 1.0: 10.3: 9.5: 9.7; antennal clava 2.3× as long as wide ( Fig. 4F View Fig ). All tibiae black, with white setae ( Fig. 4A View Fig ). Fore wing disc infuscate with dark brown setae beyond level of parastigma and gradually lightened distally, except for one hyaline cross band behind marginal vein ( Fig. 4E View Fig ). Propodeum with anterior margin V-shaped; plical region very short, the V-shaped emargination extending to propodeal foramen ( Fig. 10D View Fig ).

Etymology

From the Latin word ‘ pax ’ (‘peace’), we pray for world peace.

Description

Female

LENGTH. About 5.2 mm.

HEAD ( Fig. 4C–D, F, H View Fig ). Black with mostly purple and green metallic luster, as follows: scrobal depression, interantennal prominence, parascrobal region and lower face black to very dark purple ( Fig. 4C View Fig ), frons, vertex and temple with purple and green metallic luster ( Fig. 4D View Fig ). Setae ( Fig. 7D View Fig ) of face ( Fig. 8C View Fig ) and gena ( Fig. 8H View Fig ) white and lanceolate, setae of frons, vertex and occiput brown and hair-like, parascrobal region ( Figs 7D View Fig , 8C View Fig ) with two or three rows of white lanceolate setae ventrally and one row dorsally; maxillary and labial palpi dark brown ( Fig. 4C View Fig ). Head in frontal view 1.28 × as wide as high; in dorsal view width 1.84 × length, with interocular distance 0.18 × head width and less than width of eye; in lateral view 1.49 × as high as long. Eye height about equal to width in lateral view; distance between eyes below 3.88 × distance between eyes above; malar space 0.46 × eye height; distance between toruli greater than distance between torulus and clypeal margin, but close to the distance between torulus and orbit. OOL: POL: LOL: MPOD = 1.0: 10.3: 9.5: 9.7. Face with parascrobal region very narrow, interantennal region reticulate, scrobal depression deep and ∩-like, imbricate, with dorsal margin delimited, separated from anterior ocellus by distance equal to 0.77 × diameter of anterior ocellus; lower orbit below level of dorsal margin of torulus; lower face coriaceous ( Fig. 7D View Fig ); vertex and temple coriaceous to imbricate. Antenna dark brown, scape with blue metallic luster ( Figs 4F View Fig , 9I View Fig ); scape normal, not expanded; relative length(width) of scape = 40(9), pedicel 9.5(5), 1 st to 8 th funiculars: 5(5), 13.5(6.5), 18(7), 15(10.5), 11(10.7), 9.7(11.5), 11.5(11), 9(11), clava 28(12).

MESOSOMA. Pronotum in dorsal view ( Fig. 4B View Fig ), dark with slight green metallic luster, setae brown and hair-like; divided medially, pentagonal, imbricate. Mesoscutum ( Fig. 4B View Fig ) slightly convex anteriorly and concave posteriorly, and with lateral lobe carinate posteriorly, dark with slight greenish-purple metallic luster, anterior convex region with setae white and hair-like, setae of posterior depressed region and lateral lobe white and lanceolate. Scutellar-axillar complex ( Fig. 4B View Fig ) dark purple, setae brown and hair-like; disc flat ( Fig. 4B View Fig ) with coarsely reticulate pattern arranged longitudinally in scutellum and transversely in axillae; scutellum 1.38 × as long as broad. Prepectus ( Fig. 4G View Fig ) dark purple with margins slight yellow; tegula dark brown with white hair-like setae; mesopectus dark purple, with long white hair-like setae in a patch anterolaterally; acropleuron reddish-purple with green metallic luster. Mesopectus reticulate anterior to acropleural sulcus, acropleuron with very fine longitudinally imbricate sculpture medially but more coriaceous to reticulate anteriorly, posterior region coriaceous but with slight reticulate pattern. Propodeum ( Fig. 10D View Fig ) black with slight green metallic luster, anterior margin V-shaped; plical region very short, the V-shaped emargination extending to propodeal foramen, reticulate, with one patch of setae adjacent to spiracle anteriorly, callus obscurely coriaceous and bare, with long white hair-like setae laterally. Fore wing ( Fig. 4E View Fig ) extended to near apex of gaster, with costal cell dorsally bare except for dark brown setae in infuscate region in front of parastigma; basal cell hyaline with long white setae except infuscate basally with brown setae, mediocubital fold with sparse white setae; disc infuscate with dense brown setae except hyaline distally beyond level of postmarginal vein, and with one hyaline crossband with white setae behind marginal vein distally. Fore wing stigmal vein distinctly bent anteriorly to parallel anterior margin; SMV: MV: PMV: STV = 10.0: 6.5: 6.0: 2.0. Fore leg ( Fig. 4A, G View Fig ) black, except tarsus brown; middle leg black, tibia with dense white setae, except tarsus white to light yellow, spur yellowish-brown, mesotibial spur shorter than basitarsus of middle leg; hind leg black with dense white setae on tibia, except tarsus white to light yellow, with basitarsus longer than the following two tarsomeres combined.

GASTER ( Fig. 4A View Fig ). Elongate-lanceolate, longer than mesosoma, dark brown to black with metallic luster, except apex of syntergum and ovipositor sheaths brown; syntergum tapered to rounded apex; ovipositor sheaths slightly exserted.

Remarks

Females of this new species resemble those of Z. tubatius (Walker, 1852) because both have dense white setae on the metatibia and a complete hyaline cross-band on the fore wing, but Z. pacis sp. nov. is distinguished by its darker body color, and the scape ( Fig. 4F View Fig ) not being foliaceously dilated as for females of Z. tubatius ( Peng et al. 2018: fig. 32).

Distribution

China: Zhejiang (Oriental).
