Dolerus bimaculatus

description: Dolerus bimaculatus (Geoffroy, 1785) Tenthredo bimaculata Geoffroy in Fourcroy, 1785: 368, not 386 as given by Taeger et al. (2010). Sex not given. Syntypes (assumed). Type locality: France. The earlier description in French by Geoffroy (1762: 279, no. 16). Tenthredo tristis Fabricius, 1804: 39. Sex not given. Syntypes (assumed). Type locality: Germany ("Habitat in Germania Dr. Panzer."). Lectotype designated below. Primary homonym of Tenthredo tristis Fabricius, 1779. Type material examined and taxonomic notes. <i>Tenthredo tristis</i> Fabricius, 1804. Lectotype &amp;male; hereby designated, labelled: " <i>Tenthredo tristis</i> ", "LECTOTYPE <i>Tenthredo tristis</i> Fabricius, 1775 [sic!] des. SMBlank 2008" [red, printed], " <i>Dolerus bimaculatus</i> (Geoff.) [handwritten] det. S.M.Blank 2008 &amp;check;" [printed], " <i>Dolerus bimaculatus</i> (Geoffroy) M.Heidemaa det." [printed], " ZMUC-GISHym 1067". Left flagellum, right flagellomeres 6-7, left fore tarsomeres 4-5 missing. ZMUC. Contrary to Fabricius’ original description, the posterior half of tergum 2 is red in addition to terga 3-4. The application of the name <i>Tenthredo bimaculata</i> to this particular <i>Dolerus</i> species remains uncertain until the type material (syntype(s) in coll. E. L. Geoffroy, MNHN or Museum d’Historié Naturelle d’Autun, France?) should be located, or a neotype designated. The diagnosis by Geoffroy (1785) for <i>Tenthredo bimaculata</i> is uninformative: "deux taches blanches au corcelet", but based on the description by Geoffroy (1762) it was regarded as a possible senior synonym of <i>D. tristis</i> (F.) by de Dalla Torre (1894). Konow (1897a, 1905b) subsequently affirmed this synonymy.
