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.

Mesosoma 1.7× as long as broad; pronotum 1.8–2.0× as broad as long; mesoscutum 1.2–1.4× as broad as long; scutellum 1.1× as broad as long; dorsellum 3.3× as broad as long; propodeum 7.6–8.0× as broad as long; callus with 3–4 setae. Forewing ( Fig. 3) 2.0–2.5× as long as broad; relative measurement of veins: SMV: prestigma:MV:PMV:STV 31:6.5:30:5:16; SMV with 3–4 setae. 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).
