Diagnosis.
FEMALE. Macropterous (
Figs 3A, B
). Fore wing with hyaline cross band behind marginal vein complete and with entirely white setae (
Fig. 3F
); infuscate region basal of hyaline band with uniformly dark setae and about 2.5–3.0× wider than cross band (
Fig. 3F
); basal region with dark setae extending from discal region basally along mediocubital fold and within cubital and vanal areas, but basal cell bare or mostly bare with at most a few inconspicuous, white setae (
Fig. 3H
). Head (
Fig. 3C
) with scrobal depression distinctly separated from anterior ocellus, by distance at least equal to about 2× longitudinal diameter of ocellus. Antenna (
Figs 3B, D
) with fl2 slightly longer than pedicel (
Fig. 3D
) but not all funiculars longer than wide, with at least apical two funiculars quadrate to slightly transverse (
cf
.
Fig. 1C
). Mesosoma, including procoxa, entirely dark except sometimes for paler lateral surface of pronotum (
Figs 3B, G
), with concave posterior part of mesoscutum quite distinctly green to bluish-green compared to often somewhat coppery to reddish-violaceous rest of mesoscutum (
Fig. 3E
); mesotibial apical spur infuscate (
Fig. 3J
); mesotarsus with at least basal four tarsomeres uniformly, much paler than mesotibial apical spur and dark mesotarsal pegs (
Fig. 3J
). Mesoscutum (
Fig. 3E
) with convex anterior part of medial lobe extensively mesh-like coriaceous to granular anteriorly, and variably shallowly and distinctly reticulate posteriorly, and with posterior concave part of mesoscutum only sparsely setose with white to dark, hair-like setae; mesoscutal lateral lobe with bare, minutely mesh-like coriaceous band anterior of posteromedian carina relative to distinctly larger mesh-like coriaceous to alutaceous-imbricate sculpture on outer inclined surface (
Fig. 3E
). Profemur ventrally with short, acute tooth within about apical third (
Fig. 3I
: arrow).

Species concept.
Our concept of
A. colemani
is based on examination of the contorted, disarticulated remains of one of two original
syntype
females in the USNM labelled “Bangalore | Mysore Ind / 27.VII.09 / LC Coleman | donor No 118 / ex eggs of |
Degonetus
|
serratus
/
Anastatus
|
colemani
|
♀
| Type Cwfd / Type | No. 14344 |
U.S.
N.M.” Images of the other
syntype
female are available at: www.usnmhymtypes.com/default. asp?Action=Show_Types&Single_Type=True&TypeID=3505.
Our concept of the species is based also on
2 females
(CNC) from
Nepal
(Kathmandu,
1–25.IX.1984
, M.G. Allen, Malaise trap) and
12 females
(CNC) from
India
(Bangalore,
Karnataka
,
8–14.V.1986
,
15–21.V.1986
,
1– 9.VI.1986
,
1–10.III.1987
,
22–31.V.1987
,
1–9.IX.1987
,
18–24.IV.1988
,
16–31.V.1988
,
1–10.VI.1988
, K. Ghorpade) that we identify as
A. colemani
. Our images (
Fig. 3
) are from the two females from
Nepal
.
Regional records.
Takahashi (1940)
recorded
A. colemani
from
Taiwan
and
Hu
et al
. (2011)
from
Hainan
as a parasitoid of the eggs of
Rhynchocoris humeralis
(Thunberg, 1783)
(
Hemiptera
:
Pentatomidae
). We did not examine voucher material from
Takahashi (1940)
, but L. Peng determined from voucher specimens (IZCAS) that the identification of
A. colemani
by
Hu
et al
. (2011)
was a misidentification of
A. japonicus
. We therefore exclude
A. colemani
from the fauna of mainland
China
. We cannot exclude it as possibly present in
Taiwan
, though we suspect the identification of
A. colemani
by
Takahashi (1940)
likely is a misidentification of
A. formosanus
or some other species.
Distribution.
ORIENTAL:
China
(
Taiwan)
? (
Takahashi 1940
),
India
(
Crawford 1912
), Malaya (
Ferrière 1930
;
Corbett and Miller 1933
), *
Nepal
.
Hosts
. The
type
series of
A. colemani
was reared as a parasitoid of the eggs of
Degonetus serratus
(Distant, 1887)
(
Hemiptera
:
Pentatomidae
). Subsequent records include four other identified genera and species of
Pentatomidae
(see
Noyes 2019
) as well as
Attacus atlas
(Linnaeus, 1758)
(
Lepidoptera
:
Saturniidae
) (
Hayat 1975
;
Noyes 2019
).
Islam and Hayat (1986)
also recorded the lac insect,
Kerria lacca
(Kerr, 1782)
(
Hemiptera
:
Kerriidae
) as a host, but this record is more anomalous.
Remarks
. Females of
A. colemani
most closely resemble those of
A. bifasciatus
, but are differentiated by several features as is discussed under the latter species. In the original description of the female,
Crawford (1912
, p.7) stated “first joint of the funicle almost twice as long as pedicel” and “clava about as long as first joint of funicle”, but he apparently did not observe the reduced first flagellomere and inadvertently combined its length with that of the second flagellomere for his measurement of the “first joint”, because the combined length of the first two flagellomeres (
Fig. 3D
: fl1, fl2) is about twice the length of the pedicel (
Fig. 3D
: pdl) and of similar length to the clava. Both
Hayat (1975)
and
Narendran (2009)
keyed out
A. colemani
primarily by the first funicular being almost twice as long as the pedicel and about as long as the clava, apparently based on
Crawford (1912)
. Because of this error it is possible that
Hayat (1975)
and
Narendran (2009)
key the true females of
A. colemani
under some other name. In
Narendran (2009)
, females key most readily to those of
A. ramakrishnai
(
Mani, 1935
)
, which are also partly characterised by the profemur having a ventral tooth subapically (
Hayat 1975
;
Narendran 2009
), a similar colour pattern, and a similar setal pattern for the posterior, concave part of the median mesoscutal lobe. However,
Narendran (2009: 90)
described the convex part of the anteromedial lobe as with “raised reticulations”, which we confirm based on examined females he identified (see further under
A. dexingensis
).
