Haris A. - Gyurkovics H.: The genus Tenthredopsis Costa, 1859 in Hungary (Hymenoptera: Symphyta)
100 Natura Somogyiensis Material and methods We reidentified approximately 5000 specimens of Tenthredopsis Costa mainly from Hungary (some specimens originate from various parts of the Carpathian Basin, we list them separately). The reidentified material is deposited mainly in the Natural History Museum Budapest. The collections of Kaposvár, Zirc and Gyöngyös museums were also studied. Genitalia were dissected from the frequent species and illustrated along with their other morphological features. For identification, we consulted Blank and Ritzau (1998) completed with Benson (1968). Key to the Tenthredopsis Costa, 1859 species of Hungary The following key is the Hungarian application of the key completed by Blank and Ritzau (1998). Females 1.
