Diagnosis : Meteorus tenellus is very close to M. cinctellus . M. tenellus has a light yellow pterostigma and M. cinctellus has a dark brown pterostigma with whitish edges. The subapical five antennal articles are longer than broad in M. tenellus (0.6 times as wide as long), as long as broad in M. cinctellus (0.8–1.0 times as wide as long). Studied material : 35 specimens. Description : Size about 4mm. Antennal articles 27–30, all articles longer than broad. Head strongly contracted behind eyes. OOL=2. Eyes protruding and large. Malar space 0.4–0.6 times basal width of mandibles. Face slightly (0.9–1.1 times) broader than high and with a medial tubercle just below the antennal sockets. Clypeus protuberant and with long setae, mandibles small and strongly twisted. Precoxal sulcus deep and broad, rugose, otherwise area smooth. Propodeum with a longitudinal carina that sometime is hard to distinguish from other rugosity. Petiolar tergum long, slender and without dorsal pits. Ovipositor 2.0–4.0 times petiolar tergum. Fore wing 5 times the length of petiolar tergum. Hind coxa rugose dorsally. Forewing m-cu postfurcal or interstitial. Colour generally dark, face yellow to brown, sometimes with lighter details on the head, the legs yellow to brown. Distribution : Western Palearctic. Country records: Austria; Finland; Lithuania; Russia: Sweden; United Kingdom; Yugoslavia. Biology : This species was described by Marshall (1887) from six females bred by Bignell on the host Acleris hastiana (Lepidoptera, Tortricidae). Remarks : This species, distributed in Sweden, Lithuania and Russia, was synonymyzed by Huddleston (1981) under M. cinctellus (Spinola 1808), a name that later turned out to be a synonym ...
