Apanteles longicaudatus You et Zhou, sp. nov. (Figs 1-3)This species belongs to the grandiculus group (Nixon, 1965), and is closely related to A. grandiculus Wilkinson, but differs from the latter in that 1) the antennae are almost shorter than the body with the preapical segment almost three times as long as wide; 2) the ovipositor sheaths are fully two and half times as long as the hind tibia and the ovipositor is without a week apical sinuation.Length: (?)5.4mm, ovipositor 4.4mm; (?) 4.0mm.Host: Larvae of Synanthedon sp. (Aegeridae, Lepidoptera), collected on the tree, Pse udo sassafras sp.Holotype (?),allotype (?) , Jing'an(28.5°?N, 115.7°?E), Jiangxi Province, 1982-Ⅵ-9,collected by Sheng Jinkun. Paratype: 2 (?) (?) 4 (?) (?), same as holotype. Apanteles compressiabdominis You et Tong, sp. nov.
