Redescription

Female ( Figs 41–48 )

LENGTH. 3.5–4 mm.

Antenna ( Figs 42, 44, 46 ) with scape yellowish-brown, pedicel dark brown to black with metallic purple luster, flagellum dark brown. Pronotum ( Fig. 45 ) dark brown to black, with purple-green luster under some angles, median groove brown, and with posterolateral corner black anterior to spiracle. Mesoscutum ( Fig. 45 ) with anterior convex part of medial lobe dark with golden-purple luster, posterior concave part smooth with metallic green luster, lateral lobe dark with purple luster. Scutellar-axillar ( Fig. 45 ) metallic green. Tegula ( Fig. 41 ) dark brown, prepectus with frontal surface black and lateral surface dark brown, and acropleuron ( Fig. 41 ) black with metallic purple luster within basal anterior quarter. Legs ( Fig. 41 ) dark brown to black except front and middle legs with tibiae and tarsi, and hind leg with tarsus light brown. Metanotum and propodeum black. Gaster ( Fig. 41 ) black with base yellowish-brown.

HEAD. In frontal view ( Fig. 42 ) about 1.3 × wider than high; in dorsal view about 2.2 × wider than long, hind margin concave; in lateral view ( Fig. 44 ) about 1.71 × higher than long. Eye height about 1.78 × eye length in lateral view; distance between eyes below 2.46 × distance between eyes above; malar space 0.43 × eye height; distance between toruli 1.6 × as long as distance between torulus and clypeal edge, and 2 × distance between torulus and orbit; frontovertex much narrower than eye. OOL: POL: LOL = 2–3: 8: 8. Vertex and frons coriaceous with white setae ( Fig. 42 ); lower face ( Fig. 42 ) punctate with dense long white hair-like pubescence, medially angulate; gena alutaceous; parascrobal region ( Figs 42, 46 ) with lower portion strigose and upper portion coriaceous, interantennal region punctulate and densely setose with white lanceolate setae. Scrobal depression with scrobes ( Fig. 46 ) coriaceous, deep and channel-like, with lateral margin carinate ventrally and weakly carinate dorsally, and separated from anterior ocellus by distance equal to 0.7 × diameter of anterior ocellus. Lower orbit higher than ventral margin of torulus. Antenna with scape extended slightly beyond anterior ocellus; relative length (width) of scape = 54–60(7–8); pedicel 11–12(7–8); anellus 5(7); 1 st to 7 th funiculars: 15(8): 14–15(8.5): 15(9): 12(10): 11(10): 10(9–10): 9–10(9); clava 30(11).

BODY. Pronotum ( Fig. 45 ) in dorsal view acute-triangular, coriaceous, concave postero-medially, with five short setae along anterior margin on each side of collar and two long seta and six short setae posteriorly in front of each spiracle, median groove distinct. Mesoscutum ( Fig. 45 ). Anterior convex part of medial lobe U-shaped, 0.66 × total length of mesoscutum, distinctly longer than broad, rugose- punctate and densely setose, and posterior portion strongly concave, smooth medially to imbricate laterally, with setae in radial pattern; lateral lobe inclined, imbricate. Scutellar-axillar complex ( Fig. 45 ) convex, coarsely reticulate; scutellum 1.3 × as long as broad. Acropleuron ( Fig. 41 ) imbricate to finely strigose, anterior one-quarter with short white hair-like setae. Macropterous, fore wing ( Fig. 43 ) about 2.2–2.4 mm in length, 2.5 × as long as wide, with apex rounded and extending beyond gaster; basal plate with seven brown setae; basal cell sparsely setose with thinner setae than setae of disc; costal cell ventrally with a row of setae along length, and dorsally bare; submarginal vein with a row more than 12 white setae; disc with brown infuscation basally and apically of hyaline cross-band behind MV except about apical one-fifth more hyaline along wing margin, with basally infuscate setose region 2 × wider than hyaline cross-band; disc densely setose with thick brown setae except for white setae of hyaline cross-band; hyaline cross-band curved, not extending to junction of MV and STV; SMV: MV: PMV: STV = 53–56: 33–36: 18–19: 9.

LEGS. Profemur with ventral margin evenly arched basally, but expanded into blunt tooth within apical quarter. Middle leg ( Fig. 41 ) with spur shorter than basitarsus; tibia with apical pegs in a patch; basal four tarsomeres with black pegs on either margin. Hind leg with basitarsus as long as following three tarsomeres combined.

GASTER ( Fig. 41 ). Shorter than mesosoma; ovipositor sheath not exserted.

Notes

Of the original type material, five females and two leaf-remnants with attached egg shells were found, all with labels by Sheng. One female labeled with “species name: Anastatus papillosae sp. nov. designated by Sheng Jinkun”, here considered to be the holotype, has another two labels: “Shicheng, Jiangxi Prov., host: Tessaratoma papillosa ” and “1979, Collector:”. Another four females have the same collection label as the holotype. The holotype lacks both flagella. Of the paratypes, two are intact; one has lost both flagella, the middle legs, the left hind leg and right metatibia; one has only the head, left antenna, a broken right fore wing, as well as one middle and one hind leg remaining.

The published data for this species gives the date of collection as 1989, but the labels on the specimens have the printed year as “198_”, and a written date “79”, with “7” covering the number “8”. Consequently, we suspect these specimens were collected in 1979, but that Sheng made a mistake with the published date.

Remarks

The most important differential characters of females are as follow: 1) profemur ventrally bearing a blunt tooth at apical quarter ( Fig. 47 ); 2) anterior convex part of medial lobe U-shaped ( Fig. 45 ); 3) posterior concave part of medial lobe with setae in two radial patterns ( Fig. 45 ); 4) anellus wider than long, and 8 th flagellomere longer than wide; 5) SMV 1.3 × as long as MV. Females most closely resemble those of A. dexingensis , but A. dexingensis has a sharp profemural tooth (cf. Figs 7 , 47 ) and the anterior convex part of medial lobe is V-shaped (cf. Figs 4 , 45 ). Using Kalina (1981), A. shichengensis keys out to A. splendens , but differs from the latter species in the same features given under remarks for A. dexingensis .
