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. Tumidic. subcaud ♀” (the locality is unclear); 1 female, labeled: “Pinlack 24.8.42. Tum. subc ♀” (the locality is unclear); 1 male, labeled: “Soplicon 16.7.42. Tum sub. ♂”; 1 female, labeled on the underside: “E.K.D. ♀ 1.VII.40. Tumidiclava subcau- ♀ at N” (specimens were collected by S. Novicky using an aspirator on window panes in cars of the electric train Warsaw – Grodzisk Mazowiecki (Masovian Voivodeship, Poland); it is an abbreviation standing for “Elektryczne Koleje Dojazdowe” in Polish, the suburban railway line that operated during 1922–1947); 1 female, labeled on the underside: “E.K.D. ♀ 2.VII.40. Tum. subc. ♀ at N” (on the same pin with the previous one); 4 males on the same pin, labeled: “Fort Mo-kation 4.10.40. Tum. sub. ♂” (except one " 8.8.40 ", the locality is unclear); 6 females on the same pin, labeled: “Hortobágy 12.VII.1937 leg. Nowicki” ("Nagy Hortobágy" was one of the well-known collecting localities of S. Novicky; it is in Hortobágy National Park, Hungary).
