Redescription. FEMALE. Body length 960–1150 µm. Body and antenna mostly dark brown, legs light to dark brown.

Antenna ( Fig. 1 ) with radicle 0.2–0.3× total length of scape, rest of scape 2.35–3.45× as long as wide; pedicel much longer than F1; F1 and F2 subequal in length and the shortest funicle segments, F3 slightly longer than F4, F4 shorter than the following funicle segments, F5–F8 more or less subequal in length; mps on F3 (1), F4 (1), F5 (2), F6 (0 [or 1 on one antenna]), F7 (2) and F8 (2). Clava with 8 mps, 2.3–3.5× as long as wide.

Mesosoma slightly shorter than metasoma. Propodeum ( Fig. 2 ) usually with complete submedian carinae narrowing anteriorly and usually joining together at anterior margin of propodeum but sometimes fading at dorsellum. Fore wing ( Fig. 3 ) 2.5–2.7× as long as wide; longest marginal seta 0.1–0.2× maximum wing width; disc with a slight brownish tinge and bare behind venation except for 3 or more setae behind stigmal vein, and densely setose elsewhere. Hind wing 13.6–17.5× as long as wide; disc unevenly setose, with a slight brownish tinge; longest marginal seta 1.6–1.8× maximum wing width.

Ovipositor ( Fig. 4 ) occupying 0.9–1.0× length of gaster, not or at most barely exserted beyond the apex of gaster, 1.1–1.5× as long as mesotibia.

MALE. Unknown from China but known from other countries ( Triapitsyn 2013a).

Distribution. For C. atra s.l., Holarctic and Oriental ( Zeya & Hayat 1995; Triapitsyn 2013a); China (new record, both Palearctic and Oriental parts).

Hosts. Unknown for C. atra s.str. but see host records and discussion in Triapitsyn (2013a) for C. atra s.l.

Comments. We identify specimens from China as C. atra s. l. because they do not exactly agree with the lectotype in the shape of the propodeal carinae but fit Matthews’ (1986) and Zeya & Hayat’s (1995) concepts of the species ( Triapitsyn 2013a).
