Description.
FEMALE. Body length
860–1220
µm (dry-mounted
paratypes
). Head and mesosoma black, gaster mostly dark brown; scape and pedicel brown, flagellum brown to dark brown except F
1
sometimes a little lighter, legs mostly brown to dark brown.
Antenna (
Fig.
106
) with radicle
0.32
× total length of scape, rest of scape 3.0–
3.3
× as long as wide, weakly sculptured; pedicel much longer than F
1
; F
1
and F
2
shorter than following funicle segments, F
4
from about as long as to notably longer than F
3
, F
5
–F
8
more or less subequal in length and longer than F
1
–F
4
; mps on F
4
(almost always 0, rarely
1
on one antenna), F
5
(usually
2
, occasionally
3
on one antenna), F
6
(usually
2
, occasionally
3
, or, rarely,
1
on one antenna in small specimens), F
7
(usually
2
, sometimes
3
), and F
8
(usually
3
or
4
but sometimes
2 in
small specimens or
5 in
large specimens); clava usually with
11
or
12
mps but sometimes with only
10
mps in small specimens,
2.9–3.5
× as long as wide, at least slightly shorter than combined length of F
6
–F
8
.
Mesosoma (
Fig.
108
). Propodeum (
Fig.
107
) with submedian lines wide apart. Fore wing (
Fig.
109
)
2.7– 3.1
× as long as wide; longest marginal seta
0.23–0.26
× maximum wing width; disc with a slight brownish tinge (often almost hyaline), bare behind submarginal vein and densely setose elsewhere except with a usually large and distinct bare area between marginal vein and cubital row of setae (a row of setae always present next to marginal vein and occasionally additional, sparse setae also present behind marginal vein so that the bare area sometimes less distinct).
Hind
wing
16–20
× as long as wide; disc rather sparsely setose and almost hyaline; longest marginal seta
2.1–2.5
× maximum wing width.
Metasoma (
Fig.
108
). Gaster longer than mesosoma. Petiole
1.9–2.5
× as wide as long. Ovipositor occupying
0.7–0.9
× length of gaster, barely exserted beyond its apex (by at most
0.07
× own length); ovipositor length: mesotibia length ratio usually
1.5–1.7
:
1
but rarely about 2.0:
1 in
a few specimens.

MALE. Body length
960–1155
µm (dry-mounted specimens before slide-mounting). Similar to female except for normal sexually dimorphic features and the following. Head and mesosoma black, gaster dark brown to black, antenna brown, legs mostly brown to dark brown. Antenna as in
Fig.
110
, scape with cross-ridges. Wings (
Fig.
111
) hyaline; fore wing
2.6
–3.0× (usually
2.7–2.8
×) as long as wide. Genitalia as in
Fig.
112
.
Diagnosis.
Gonatocerus katraps
does not resemble any European species of
G.
(
Lymaenon
) except perhaps
G. acuminatus
which has a much longer, distinctly exserted ovipositor. It is somewhat similar to
G.
(
Lymaenon
)
bakrotus
Mani & Saraswat
from high elevation in northern
India
(
Mani & Saraswat
1973
), and to the lesser extent, also to
G.
(
Lymaenon
)
narayani
(Subba Rao & Kaur)
from
Bangladesh
,
India
, and
Thailand
(
Zeya & Hayat
1995
;
Zeya & Khan
2011
).
Gonatocerus katraps
differs from
G. bakrotus
in having a distinct bare area on the fore wing disc between the marginal vein and the cubital row of setae (
Figs
109
,
111
), and from
G. narayani
by the much darker body color.
Etymology.
The species name is an arbitrary combination of letters treated as a noun in apposition.
Hosts.
Unknown.

katraps
Ƥ (paratypes, Gornotayozhnoye, Primorskiy kray, Russia): 106, antenna; 107, dorsellum and propodeum; 108, mesosoma and metasoma; 109, fore wing.
Comments.
The following two small female specimens most likely belong to
G. katraps
but are not included in the
paratype
series because they have relatively shorter F
5
–F
8
of the antenna, a narrower fore wing (
3.3–3.45
× as long as wide), and a relatively shorter ovipositor (
1.3–1.4
× as long as mesotibia) than the typical
G. katraps
:
