Diagnosis. Zagrammosoma talitzkii is characterized by a large speculum, and basal vein fold that is asetose or at most with 1–2 setae ( Fig. 40C ). The species is most similar to Z. americanum and Z. occidentale , however the wing patterns are unique to each species ( Figs 4C , 36C , 40C ). Only the stigmal band is present in Z. talitzkii , extending just past the stigmal apex, unlike the other two species, which have varying degrees of extension of the parastigmal, stigmal, and postmarginal bands.

Description. Female - body length 1.88–2.22 mm. Metallic luster on body absent. Scape yellow with black stripe dorsally. Lower face with median stripe absent. Vertex with 2 stripes above compound eye. Gena posteriorly with dark stripes below compound eye. Occiput yellow with 2 dark, vertical stripes. Pronotum with median stripe complete; laterally with 2 black stripes. Prepectus all yellow. Mesoscutum with median stripe interrupted. Mesoscutellum yellow with three dark stripes. Propodeum yellow with black median carina, posterior and sometimes anterior margins, and stripe or spot laterally. Procoxa, mesocoxa, and metacoxa yellow. Profemur and mesofemur yellow. Metafemur with interrupted or uninterrupted stripe dorsally. Fore wing: basal and cubital bands absent; parastigmal band present, at junction of parastigmal and marginal veins only; stigmal band present, at junction of marginal and stigmal veins only, or with perpendicular extension less than or greater than that of stigmal apex; postmarginal band absent; connection from parastigmal band to stigmal band absent. Hind wing hyaline. Gaster yellow with dark median and transverse stripes present.

Upper ocular sulcus present. Pedicel longer than wide. Funiculars symmetrical: first longer than wide (w:l = 0.83–0.9); second wider than long (w:l = 1.06–1.11).

Pronotum, in dorsal view, bell-shaped (w:l = 1.65–2.0); 3–5 pairs of setae along posterior margin. Mesoscutum reticulate; small, scattered setae present; intermediate setae absent. Mesoscutellum wider than long (w:l = 1.06–1.2); submedian grooves present. Hind tibial spur distinctly shorter than basitarsus. Hind basitarsus longer than second tarsomere, (bst:2 nd = 0.87–0.9).

Fore wing l:w = 2.1–2.27. Submarginal vein with 5–7 setae dorsally. Basal fold asetose or with 1–2 setae. Cubital fold asetose, with line of setae complete or incomplete to basal fold. Admarginal setae absent. Uncus originating on stigma by more than own length from stigmal apex.

Male - as female, except: body length 1.24–1.3 mm; gaster with transverse stripes and median spots.

Remarks. Zagrammosoma dulanense is synonymized with Z. talitzkii as the differences between the two species are within-species variation. Cao & Zhu (2014) remark that the black spots on Gt 6 are in a line in Z. dulanense and in a triangular configuration in Z. talitzkii , however, examination of a paratype and other specimens identified by Bouček, reveals variation of these black spots within Z. talitzkii . The black, transverse stripe along the anterior margin of the mesoscutum is present in Z. talitzkii but partially obscured by the posterior margin of the pronotum. The mesosoma color pattern variation is less variable than that found in Z. melinum or Z. occidentale . A specimen from China that agrees with the description of Z. dulanense is recovered as Z. talitzkii in the molecular analysis ( Fig. 2 ).
