does not start on the same level as M, but slightly back towards the basal part of wing (Fig. 84). Tarsal claws very narrow, long, simple, without basal lobe (Fig. 85). Metasoma longer than head+mesosoma and much higher than mesosoma, strongly compressed laterally; all tergites smooth, shiny, without punctures, yellow, dark brown dorsally and dorso-laterally; metasomal tergite 2 occupies 1/3 of metasoma in dorsal view (Fig. 90). Ventral spine of hypopygium very short, prominent part only very slightly longer than broad, with long white subapical setae, the most apical setae extending beyond the apex of hypopygium (Fig. 91). Male unknown. Gall (Fig. 92). The gall develops from a bud on Q. brantii, conical, at the base 10 mm in diameter, 12 mm high. Interior spongy, moist, juicy, green when young, becoming brown after the gall matures. Multilocular (5 chambers were found in one gall). The larval chambers cannot be separated from the spongy parenchyma. The gall to some extent resembles that of Dryocosmus mayri MÜLLNHR, 1901 (Fig. 119), however, the latter is known to aggregate in clusters, while in D. tavakolii galls occur singly. Figs 79-85. Dryocosmus tavakolii sp. n.: 79-80, head: 79 = frontal view, 80 = dorsal view, 81 = posterior view, 82 = lateral view, 83 = antenna, 84 = forewing, 85 = hind tarsal claw
