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.

Tenthredo tristis Fabricius, 1804. Lectotype ♂ hereby designated, labelled: " Tenthredo tristis ", "LECTOTYPE Tenthredo tristis Fabricius, 1775 [sic!] des. SMBlank 2008" [red, printed], " Dolerus bimaculatus (Geoff.) [handwritten] det. S.M.Blank 2008 ✓" [printed], " Dolerus bimaculatus (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 Tenthredo bimaculata to this particular Dolerus 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 Tenthredo bimaculata is uninformative: "deux taches blanches au corcelet", but based on the description by Geoffroy (1762) it was regarded as a possible senior synonym of D. tristis (F.) by de Dalla Torre (1894). Konow (1897a, 1905b) subsequently affirmed this synonymy.
