Material examined. Holotype ♀ (FAFU). “ CHINA: Chebaling, Shaoguan, Guangdong Province | 25.v.2002 | LIU Changming / Holotype ”.
Paratypes 2♀ (FAFU), CHINA: same data as holotype.
Description of holotype. FEMALE. Body length excluding ovipositor sheath 2.75 mm.
Head (Figs 22A, F, H) primarily bright bluish-green. Head in frontal view (Fig. 22F) 1.58× wider than high; frons coriaceous-granular, parascrobal region rugose, with two rows of hair-like setae; interantennal region transversely reticulate-imbricate, with hair-like setae; lower face reticulate rugose, and medially angulate, with white hair-like to very slightly lanceolate setae; scrobal depression with scrobe deep, lateral margin strongly carinate, dorsally separated from anterior ocellus by distance equal to longitudinal diameter of anterior ocellus; distance between eyes below 2.0× distance between eyes above, lower orbit in line with ventral margin of torulus; distance between toruli 1.26× distance between torulus and clypeal edge, and 2.1× distance between torulus and orbit. Head in dorsal view (Fig. 22A) with width 1.95× length, with interocular distance about 0.3× head width and less than width of eye; vertex transversely reticulate to strigose, with long brown lanceolate setae. Head in lateral view (Fig. 22H) almost square, with vertex almost straight, face evenly convex, 1.14× higher than long; gena reticulate, with white hair-like setae; eye height 1.31× eye width in lateral view; malar space 0.26× eye height; distance between a posterior ocellus and inner orbit: distance between posterior ocelli: distance between the anterior and a posterior ocellus: maximum diameter of a posterior ocellus = 3: 5: 4.7: 3. Antenna (Figs 22D, F) with scape yellowish-brown, pedicel slightly darker than scape and with purple metallic luster, flagellum dark brown, scape 0.35 mm; relative length(width) of scape = 35(4); pedicel 9(4); first to eighth funiculars: 5(4), 11(4), 11.5(4), 13(6), 11(6), 10(6.5), 9(7), 8(7); clava 19(10). Maxillary and labial palpi brown to dark brown.
Pronotum (Fig. 22E) yellowish-brown with purple metallic luster under some angles of light, except spiracular rim very dark brown; in dorsal view pentangular, weakly coriaceous, divided medially, slightly concave in middle of disc, setae pale. Mesoscutum (Fig. 22E) with posterior concave part brown with purple metallic luster under some angles of light, but otherwise paler yellowish-brown; anterior convex part of medial lobe teardrop-shaped, 0.63× total length of mesoscutum, coarsely punctate-reticulate with white hair-like setae; posteriorly concave part of mesoscutum smooth, and with white, laterally directed setae; lateral lobe with inclined inner surface slightly coriaceous, with white setae along lateral margin. Scutellar-axillar complex (Fig. 22E) convex, brown, coarsely punctate-reticulate, scutellum 2.0× longer than broad. Brachypterous; fore wing (Figs 22E, G) 0.5 mm in length, blade like, acutely angled apically; disc hyaline, sparsely setose with hyaline setae, apical third with pale yellow setae. Tegula yellowish-brown (Fig. 22E). Mesopleurosternum (Fig. 22C) with mesopectus brown, finely meshlike reticulate, with white hair-like setae; acropleuron yellowish except about posterior 1/3 brown, and with fine longitudinally aligned coriaceous sculpture. Metanotum and propodeum brown (Fig. 22E); propodeum with plical depression U-shaped, plical region sublinear medially (Fig. 22E). Legs (Fig. 22B) yellowish-brown except dorsal margin of femora and tibiae brown and mesotarsal pegs black; ventral margin of profemur evenly arched, not toothed; mesotibial apical spur pale, slightly shorter than basitarsus; mesotarsus with all tarsomeres pale in contrast with dark mesotarsal pegs; hind leg with basitarsus slightly shorter than following three tarsomeres combined.
Gaster (Figs 22A, B) mostly dark brown with metallic luster under some angles, and base partly yellowishbrown; apex of syntergum and ovipositor yellowish-brown, gaster longer than mesosoma, finely reticulate; ovipositor not exserted.
MALE. Unknown.
Variation. The female paratypes are mostly similar to the holotype except the scrobal depression is separated from the anterior ocellus by a distance equal to 1.2× the longitudinal diameter of the anterior ocellus.
Etymology. The species name is derived from the Latin words ‘ parilis ’ (like, similar) and ‘ quadrus ’ (square), in reference to the head being subquadrate in lateral view.
Host. Unknown.
Distribution. ORIENTAL: China (Guangdong).
Remarks. This new species is one of four species known from China with short-winged females (Fig. 22G). Females resemble those of A. meilingensis, but are differentiated easily by the shape and sculpture of the anterior convex part of the mesoscutum. The reduced fore wings of A. pariliquadrus females are acutely angled apically, lack a hyaline cross band, and have strongly reduced stigmal and postmarginal veins, whereas the other three species with short-winged females all have the fore wings rounded apically with a distinct hyaline cross band (Figs 7F, 14H, I) or are truncate apically with at most a remnant of a cross band (Fig. 18F: cbr).
