Diagnosis.
Female.
Macropterous (
Fig. 1A
); fore wing with broad hyaline cross band behind marginal vein with similarly curved basal and apical margins so band uniformly wide, and without isolated dark setae medially (
Fig. 1E
). Mesosoma (excluding legs) dark except prepectus and lateral, vertical surface of pronotum entirely or mostly pale (
Fig. 1
A-D
); procoxa dark, similar in color to prosternum and acropleuron (
Fig. 1D
). Mesoscutum with posterior concave portion almost entire setose (
Fig. 1C
). Mesotarsus with basal two tarsomeres infuscate over at least dorsal and posterior surfaces, obviously darker than subsequent two tarsomeres (
Fig. 3F, G
). Antenna with at least apical funicular slightly transverse and previous one or two funiculars subquadrate (
Fig. 1B
).

Male.
Structure plus color, setal and sculptural patterns (
Fig. 1F
) similar to those described for
A. gansuensis
except clava at least about as long as combined length of fl6-fl8 + 0.25 apical length of fl5 (
Fig. 1G, H
), and sometimes as long as combined length of fl5-fl8, with fl8 quadrate to slightly transverse, fl7 quadrate to slightly longer than wide, and fl6 and fl5 longer than wide (
Fig. 1H
).
Distribution
.
Anastatus fulloi
(Genbank accession no. MK604241) was described originally from Jiangxi Province from two localities (Wuyi Mountains and Meiling) (
Sheng et al. 1997
) as detailed by Peng et al. (1997). We reared it in the field from the following two new localities:
Gansu Province
: Longnan City, collected 23.I.2018, Yong-Ming Chen (1♀, 1♂ AICF; 1♀, 1♂ BMNH; 19♀, 21♂ CNC; 5♀, 3♂ FAFU; 12♀,7♂ IZCAS; 1♀, 1♂ USNM).
Liaoning Province
: Benxi, Manchu Autonomous Co., Benxi City, Tai Shan Forest Farm, 23.IV.2017, Yong-Ming Chen.
Hosts.
The type series was reared from the eggs of the yellow spotted stink bug,
Erthesina fullo
(Thunberg, 1783) (
Hemiptera
,
Pentatomidae
). Here we newly report it as an egg parasitoid of the lepidopteran hosts
C. japonica
and, in the laboratory,
A. pernyi
.
Remarks.
Of the species we reared from
C. japonica
, females of
A. fulloi
are most similar to those of
A. gansuensis
because they are fully winged (cf.
A. meilingensis
) and have a dark acropleuron that does not contrast with the mesonotum (cf.
A. japonicus
). However, females differ from those of
A. fulloi
in color, setal and structural features, as given in the key to species and diagnoses.
Sheng et al. (1997
, fig. 14) and
Peng et al. (2017
, figs 25, 26) described and illustrated the flagellar structure of males from the type series of
A. fulloi
reared from
E. fullo
; they have the clava at least as long as the previous four segments combined. However, the males we reared with females from
A. pernyi
eggs that we identify as
A. fulloi
have the clava quite obviously shorter than the combined length of the four preceding funiculars (
Figs 1G, H
), being about as long as the combined length of fl6-fl8 plus about the apical quarter (
Fig. 1H
) to half of fl5. The difference between the flagellar structures observed between our males and those of the type series could be explained by populational or host correlated differences or, perhaps, indicate two cryptic species that are more host-taxon restricted than is currently considered for
A. fulloi
. Regardless, compared to males of
A. gansuensis
(
Fig. 4H
) and
A. meilingensis
(
Fig. 6H
), males of
A. fulloi
(
Fig. 1H
) have somewhat short apical funiculars so that the clava relative to the combined length of the funiculars is greater. Because of similarity in their flagellar structures (cf.
Figs 1H
,
5H
) we cannot currently reliably differentiate
A. fulloi
from
A. japonicus
males.
