title: European Rhogogaster s. str., with notes on several Asian species (Hymenoptera: Tenthredinidae).
abstract: The European Rhogogaster s. str. species are revised, and several nominal taxa from Asia discussed. The taxonomic identity of the type species Tenthredo viridis Linnaeus, 1758 is different from that assumed in the past. Tenthredo dryas Benson, 1943 is syn. nov. of R. viridis. The name Rhogogaster scalaris (Klug, 1817), species revocata, is to be applied to Rhogogaster viridis auct. New subjective junior synonyms of R. scalaris (Klug, 1817) are R. chlorosoma podkumokensis Muche, 1973, syn. nov. and Tenthredo (Rhogogaster) carpatica Zhelochovtsev & Zinovjev, 1988, syn. nov. Rhogogaster magniserrula Viitasaari, spec. nov. is described from Finland and Russia. The former synonym of R. viridis auct., Tenthredo hebraica Geoffroy in Fourcroy, 1785, is treated as species incertae sedis within Rhogogaster. The Asian Rhogogaster viridis var. sibirica Enslin, 1912, is regarded as a valid species, Rhogogaster sibirica Enslin, 1912, stat. nov., and Rhogogaster kudiana Rohwer, 1925, is a subjective syn. nov. of R. sibirica. A key to the European Rhogogaster s. str. with special emphasis on Fennoscandia is given.The following nominal taxa are excluded from Rhogogaster: Rhogogaster viridis forma montana Betrem, 1933, is syn. nov. of Tenthredo olivacea Klug, 1817; Sciapteryx virescens Jakowlew, 1887, is Tenthredo (Eurogaster) virescens (Jakowlew, 1887), comb. nov.; Tenthredo interrupta Fabricius, 1804 (nomen oblitum) is syn. nov. of Tenthredopsis tessellata (Klug, 1817) (nomen protectum). Tenthredo viridis Poda, 1761, Tenthredo straminea Schrank, 1776, Tenthredo annalicornis [sic!] Gmelin, 1790, and Tenthredo chloros Rudow, 1871 are considered to be species incertae sedis within Tenthredinidae.Lectotypes are designated for Tenthredo interrupta Fabricius, 1804, Sciapteryx virescens Jakowlew, 1887, Sciopteryx gilva Konow, 1908, Rhogogaster viridis var. sibirica Enslin, 1912, R. viridis forma montana Betrem, 1933, R. chlorosoma podkumokensis Muche, 1973, R. genistae viridifrons Muche, 1973 and Tenthredo (Rhogogaster) carpatica "Bokotey" [= Zhelochovtsev & Zinovjev], 1988.
