Remarks

This species is known as a gall-stem wasp of Phragmites australis . Tetramesa phragmitis is widely distributed in the Palaearctic region from Europe to Japan ( Bouček 1968; Zerova 1978; Kalina 1989; Zerova & Fursov 2016).

This species has recently been redescribed ( Zerova & Fursov 2016) and our specimens exhibit the following variations: body larger, 5 mm (vs 2.7–4.3 mm in Zerova & Fursov 2016), mainly dark, with yellow spots reduced to head, below eyes and lower face ( Fig. 9A, E ) vs yellow spots on head and thorax, also much lighter specimens occur in Israel and Tajikistan ( Zerova & Fursov 2016). Fore wing ( Fig. 9C ) mainly infuscate with two distinct dark spots, the first one under marginal and stigmal veins and the second as a V-shaped dark spot below submarginal vein vs unclear yellow spot under marginal vein ( Zerova & Fursov 2016); and distinctly dark-brown veins vs yellowish veins ( Zerova & Fursov 2016).
