Diagnosis.
FEMALE. Macropterous (
Figs 6A, B
). Fore wing with anterior and posterior hyaline spot with white setae behind marginal vein separated by infuscate region with dark setae similar to elsewhere within infuscation (
Figs 6A, H
); infuscate region basal to hyaline spots with dark setae similar to elsewhere or with region of paler, more orangish setae extending at least to level of medial fold (
Fig. 6H
); basal region with basal cell and cubital and vanal areas extensively setose, the cubital and vanal areas usually with dark setae but basal cell with inconspicuous white setae (
Fig. 6I
). Head (
Fig. 6F
) with scrobal depression distinctly separated from anterior ocellus, by distance equal to about 1–2× longitudinal diameter of ocellus. Antenna (
Fig. 6C
) with fl2 longer than pedicel (
Fig. 6G
) but not all funiculars longer than wide, the apical 1–3 funiculars quadrate to slightly transverse (
Fig. 6C
, insert). Mesosoma with at least mesonotum (
Fig. 6E
) dark with metallic green luster and pronotum, prepectus, tegula and acropleuron similarly dark brown as mesonotum or variably paler brown to contrastingly orangish; procoxa pale to variably dark brown similar to acropleuron; mesotibial apical spur uniformly pale; mesotarsus with at least basal four tarsomeres pale similar to mesotibial apical spur (
Fig. 6D
) and much lighter than dark mesotarsal pegs. Mesoscutum (
Fig. 6E
) with convex anterior part of medial lobe entirely punctate-reticulate and with posterior concave part of mesoscutum broadly setose with white setae medially, though apices of setae not extending laterally to carinate margin of lateral lobe; mesoscutal lateral lobe with bare, minutely mesh-like coriaceous band anterior of posteromedian carina relative to smoother and shinier outer inclined surface. Profemur with ventral margin evenly curved, without distinct angulation or tooth apically (

.
Fig. 1H
).
MALE. Undescribed.
Species concept.
Our concept of
A. echidna
is based on original
type
material and other females listed in
Gibson (2020)
.
Regional records.
Yang
et al
. (2015b)
previously reported
A. echidna
, under the name
A. acherontiae
, as an egg parasitoid of
Pentatomidae
and Arctiinae (
Lepidoptera
:
Erebidae
) in
Hebei
and
Hunan
provinces.

If
A. acherontiae
and/or
A. amarus
(
Subba Rao, 1957
)
are junior synonyms of
A. echidna
(see further below) then additional hosts have been reported under these names (see
Noyes 2019
).
Remarks.
This is the only currently known species of
Anastatus
from
China
whose females have two hyaline spots with white setae separated medially by an infuscate region with dark setae (
Fig. 6H
). The females of other recognised species have a complete hyaline cross band, though some of these do have some dark setae medially within the hyaline band (
e.g.
,
A. dexingensis
,
Fig. 4I and
A
. gansuensis,
Fig. 12I
).
Yang
et al
. (2015b)
was the first to report this species from
China
, but as
A. acherontiae
.
Gibson (2020)
redescribed and imaged the remaining
type
material of
A. echidna
. Based on the keys and illustrations of
Narayanan
et al
. (1960)
,
Hayat (1975)
,
Mani (1989)
, and
Narendran (2009)
, as well as females that had been identified as
A. acherontiae
or
A. amarus
by various experts, he suggested that one or both of these names could be junior synonyms of
A. echidna
. Formal synonymy of the names was not possible because
type
specimens of the latter two names were not examined; however, we did examine voucher material from
Yang
et al.
(2015b)
and confirm that what was identified as
A. acherontiae
is
A. echidna
in the sense of
Gibson (2020)
.
