Anastatus (Anastatus) meilingensis Sheng   Fig. 6 A–H View Figure 6

Anastatus meilingensis   Sheng, 1998: 5-6, fig. 1; holotype (JLAU), examined.

Anastaus meilingensis   ; Peng et al. 2017: 16-18, figs 34-40.


Female. Brachypterous, fore wing extending only to about level of posterior margin of Gt1 when body uncontorted ( Fig. 6A, B View Figure 6 ); basal 0.6 × (basal region) hyaline and much more sparsely setose than densely setose apical 0.4 × (discal region) ( Fig. 6C View Figure 6 ); basal region with slightly lanceolate dark setae extending from discal region for half-length within slender vanal region and with white or mostly white hair-like setae immediately anterior to venal fold and at least narrowly along base of discal region, though often bare behind submarginal vein; discal region uniformly covered with slightly lanceolate dark setae except for conspicuous region of orangish setae medially and often variably conspicuous but slender, sometimes interrupted remnant of hyaline cross band apically ( Fig. 6 View Figure 6 : cbr), with orangish setae extending at least to leading margin, including part of marginal vein, though sometimes not to posterior margin of wing so as to be enclosed by dark setae basally and apically and sometimes posteriorly; submarginal vein, including parastigma, extending slightly beyond basal region and partly orangish marginal vein extending most of length of discal region, without differentiated stigmal or postmarginal veins. Mesosoma (excluding legs) with prosternum dark but pronotum mostly pale except for dark spot anterior to each spiracle ( Fig. 6C View Figure 6 ) and posterolateral, vertical surface (panel) often brown to dark ( Fig. 6D View Figure 6 ); prepectus ( Fig. 6D View Figure 6 ) and tegula ( Fig. 6C View Figure 6 ) at least basally pale; mesonotum ( Fig. 6C View Figure 6 ) with scutellar-axillar complex and mesoscutum medially dark, but mesoscutal lateral lobes with at least outer, inclined surfaces partly to mostly pale; acropleuron mostly pale except dark anteriorly in region ventral to tegula ( Fig. 6D View Figure 6 ); procoxa, except often in part laterally, similarly pale as at least anterolateral surface of pronotum and most of acropleuron ( Fig. 6D View Figure 6 ); mesotarsus with all tarsomeres similarly pale yellowish to white ( Fig. 6B View Figure 6 ). Mesoscutum with posterior concave part completely setose with white setae ( Fig. 6C View Figure 6 ). Antenna with at least apical funicular subquadrate and previous two funiculars only slightly longer than wide.

Male. Structure as well as color, setae and sculptural patterns ( Fig. 6 F–H View Figure 6 ) similar to those described for A. gansuensis   except about basal half of metatibia pale and apical half lighter brown, lighter in color than respective femur ( Fig. 6F View Figure 6 ).


Anastatus meilingensis   (Genbank accession no. MK604242) was described originally from Jiangxi Province from three localities (Shangrao, Yushan, and Meiling, Nanchang) as detailed by Peng et al. (2017). We reared A. fulloi   in the field from the following new locality: Gansu Province: Kang Co., Longnan City, 23.I.2018, Yong-Ming Chen (2♀, 2♂ AICF; 2♀, 2♂ BMNH; 58♀, 36♂ CNC; 5♀, 3♂ FAFU; 15♀,12♂ IZCAS; 2♀, 2♂ USNM).


Originally described reared from the eggs of the pine moth, Dendrolimus punctatus   Walker, and of the Simao pine moth, D. kikuchii   Matsumura ( Lepidoptera  , Lasiocampidae   ) (Sheng and Yu 1988). Here we newly report it as an egg parasitoid of C. japonica   and, in the laboratory, of A. pernyi   .


Of the species we reared from C. japonica   , females of A. meilingensis   are readily distinguished because they are the only ones that are brachypterous. The fore wing color pattern, with the discal region having a distinct region of orangish setae behind the venation and often also a slender remnant of a hyaline cross band more apically ( Fig. 6E View Figure 6 : cbr), is unique among described Anastatus   species with brachypterous females. However, except for the reduced hyaline cross band, the setal pattern is similar to that described for A. gansuensis   . Females of one other described Anastatus   species from China, those of A. huangi   Sheng & Yu (1998), are also brachypterous. However, the reduced fore wings of female A. huangi   have a color pattern more similar to macropterous females, having a distinct hyaline cross band with white, hair-like setae behind the marginal vein ( Peng et al. 2017, fig. 32).

Although Sheng and Yu (1998) reared a single male as part of the type series of A. meilingensis   this male was not found by Peng et al. (2017). The line drawn figure of the antenna stated as that of a male by Sheng and Yu (1998, fig. 4) is obviously that of a female because of the presence of a visible, anelliform fl1, and a three segmented clava. Of the species treated, males of A. meilingensis   are mostly similar to those of A. gansuensis   because both have a clava that is distinctly shorter than the combined length of the apical funiculars ( Figs 4H View Figure 4 , 6H View Figure 6 ). However, based on our reared material males of A. meilingensis   have a different metatibial color pattern, the metatibia being more extensively pale basally and lighter brown apically than for males of A. gansuensis   (cf. Figs 4B View Figure 4 , 6F View Figure 6 ).
