Cirrospilus talitzkii BouČek, 1961: 18 .

Zagrammosoma talitzkii (BouČek): Yefremova 1995 a: 50.

Female of this species had been unknown at the time of the original description (BouČek 1961), but was briefly described and illustrated later (Yefremova 1995 a: p. 51). Cao at al. (2014) included female of Z. talitzkii in the key to the Asian Zagrammosoma species without its description.

Diagnosis: Female. Length 2.1–2.3 mm. Antenna: F1 1.6–1.8× as long as broad, 1.46× as long as F2, clava 2.3× as long as broad (Fig. 3). Pronotum yellow with 2 narrow lateral dark stripes. Forewing 2.5× as long as broad. Triangular area between PMV and STV bare (Fig. 3). Parastigma and stigmal vein fuscate (Fig. 3). SMV with 3–4 setae. STV 3.0–3.2× as long as PMV. Gaster yellow with black transverse stripes, Gt7 tergite with one black spot, Gt6 with 3 spots.

Male. Length 1.3–2.0 mm. Body light yellow with few black stripes or lines on the thorax and brown-black spots on the gaster. There are two lateral dark lines on the pronotum, upper and lower (Fig. 4). Antenna: F1 and F2 almost 2× longer than broad. Thorax and forewing as in Fig. 4. Dorsellum almost 2× shorter than propodeum. Forewing: stigma vein 3.0× shorter than broad of forewing and 2.0× shorter than marginal vein; postmarginal vein almost 2.0× shorter than stigma vein; fringe very short.

Description: Female. Body length 2.1–2.3 mm.

Color. Body yellow with black stripes and spots (Fig. 1), frons yellow with two black stripes laterally extending from vertex to upper lateral eye margin (Fig. 2). Antenna brownish, scape and pedicel yellow (Fig. 2). Pronotum, mesoscutum scutellum and propodeum yellow with longitudinal black stripes (Fig. 1). Propodeum with dark stripe along the anterior margin and with median line of both sides of median carina. Metasoma yellow with black transverse stripes. Forewings hyaline; veins yellow with fuscate parastigma and STV (Fig. 3). Legs yellow. Sheaths of ovipositor black in posterior half, Gt7 tergite with one black spot, Gt6 with 3 spots.

Head: POL 1.8× as OOL. Antenna (Fig. 2): scape 3.7× as long as broad, pedicel 1.75× as long as broad, F1 1.8× as long as broad and 1.46× as long as F2, F2 1.0× as long as broad, clava 1.6× as long as broad.

Forewing STV 3.0– 3.2× as long as PMV, MV 1.9–2.0× as long as STV. Triangular area between PMV and STV bare, MV with 13 setae. Admarginal setae present. Speculum open.

Gaster 2.0–2.3× as long as broad.

Male. Body length 1.3–2.0 mm. Antenna: F1 1.75× as long as broad, F2 1.2× as long as broad, clava 2.6× as long as broad; F1 1.2× as long as F2. Gaster 1.75–1.8× as long as broad (Fig. 4).
