Redescription
(based on specimens from
China
and
Kyrgyzstan
). FEMALE. Body dark brown except eyes red, femora brown, and tibiae and tarsi yellow except metatarsus slightly brown. Body length
0.85–1.12 mm
(n = 5).
Head brown, oblate in frontal view; eye 0.54× height of head (0.11–0.67×). Maxillary palp short, 1-segmented. Antenna (
Fig. 7
) rather long, with scape 3.27× as long as wide (2.08–3.8×); pedicel a little wider than scape and 2.01× as long as wide (1.5–2.27×); scape length/pedicel length = 1.56 (1.48–1.67); first anellus large, second small and hidden in basal cavity of club; club 3-segmented, 2.46× as long as wide (2.32–2.68×), first claval segment the shortest, apical segment the longest and with 7 PLS, terminal process longer than second segment, its length/club length = 0.229 (11/48).
Mesoscutum with reticulate sculpture (
Fig. 8
); midlobe with 4 setae. Fore wing (
Fig. 9
) 2.20× as long as wide (2.14–2.27×), with brown area behind apex of submarginal vein; venation long, extending 0.46× FWL, disc densely setae, setae irregularly arranged. Fringe setae short, FWFS/FWW = 0.11 (0.10–0.12).
Hind
wing with 1 complete linear setal track. First tarsal segments of all legs short, second and third segments equal in length.
Metasoma longer than mesosoma; ovipositor long and slightly exserted, arising from the fourth gastral sternite, ovipositor/hind tibia length = 1.8 (1.7–1.9).
MALE. Effectively, albeit briefly, described by Fursov (2007) in his key; his material was not available to us. The males listed below under "Comments", identified as this species by S. Novicky, need remounting and thus until then are unsuitable for redescription.
Distribution.
China
(Xinjiang) (new record),
Hungary
(
Erdös 1956
),
Kyrgyzstan
(new record),
Poland
(new record),
Russia
(European part) (Fursov 2007), and
Ukraine
(
Nowicki 1940
[as
Poland
]; Nikol’skaya &
Trjapitzin 1978
; Fursov 2007).
Hosts.
Unknown.
Comments.
This species was described originally by Nowicki from the
holotype
female collected at “Krzemieniec, Volhynia (South Eastern
Poland
)” (
Nowicki 1936, p. 141
), which is now Kremenets, Ternopil Oblast of
Ukraine
.
Viggiani (2011)
mentioned
15 specimens
of
T. subcaudata
in the S. Novicky collection at Dipartimento di Entomologia e Zoologia Agraria “Filippo Silvestri”, Università degli Studi di Napoli “Federico II”, Portici, Napoli, Campania,
Italy
(DEZA). S. V. Triapitsyn examined these specimens during a visit, but, unfortunately, the
holotype
was not among them and thus can be considered lost because it could neither be found in the Natural History Museum, London,
England
,
UK
(BMNH), where a much smaller part of the S. Novicky (Nowicki) collection of
Trichogrammatidae
is also deposited. After the non-type specimens of
T. subcaudata
in DEZA are properly remounted from the completely dried water-soluble solution in
Canada
balsam, a
neotype
can be designated from one of the females, if necessary. The data on these specimens, which are mounted on microslides in the typical style of S. Novicky (
Viggiani 2011
), are as follows [DEZA]:
1 female
, labeled: “Soplicon
16.7.42

1 female
