Type material examined and taxonomic notes.

Dolerus fumosus Stephens, 1835. Lectotype ♀ hereby designated, labelled: "Type H.T." [round with wide red margin, printed], "B.M. TYPE HYM. [printed] 1.572.", "B.M. TYPE HYM. [printed] Dolerus fumosus ( Stephens 1835)", " Dolerus fumosus .", "Stephens Coll. 53-46" [printed], " Lectotypus 2012 Dolerus fumosus ♀ [the symbol handwritten] Stephens, 1835 M.Heidemaa des." [red, printed], " Dolerus sanguinicollis Klug M.Heidemaa det." [printed] [Identified before it became clear that two species were mixed up under this name.] Condition poor: mid- and hind tarsi incomplete, 2 apical flagellomeres of the right antenna missing, abdomen partly damaged. BMNH.

Kirby (1882) referred to the "Types (♂, ♀)". The number of syntypes of D. fumosus was not given by Stephens, but only one syntype female is now present in the collection (BMNH).

Dolerus lucens André, 1880. Lectotype ♂ hereby designated, labelled: “Jászó” [Type locality: Hungary, Jászó (Jasov)], “272”, “Hongrie” [printed in block letters], " D. lucens , André.” [printed], "DEI GISHym 89371" [printed], "coll. Desbrochers [handwritten] k. [kollektsija = coll.] A. Jakovleva [nomin. A. Jakovlev]" [printed], "SYNTYPUS [printed in red] Dolerus lucens ANDRÉ, 1880 [handwritten] teste A. Taeger 20[printed]18 [handwritten]" [white label with a red frame], " Lectotypus [printed] Dolerus lucens André, 1880 [handwritten] M.Heidemaa des. [printed]" [red label], " Dolerus fumosus Stephens, 1835 M.Heidemaa det." [white, printed], ZIN. Paralectotype: 1♂ with same original collecting labels as the lectotype, but the no. is “271” and " Dolerus lucens André (typ.)" [handwritten, probably by Ed. André]. Left forewing missing. HNHM.

The paralectotype of D. lucens mentioned above bears a lectotype label by L. Zombori (" Lectotypus ♂ Dolerus lucens [ …] des. Zombori 1980"), but Zombori never published a lectotype designation. Although the paralectotype male has a handwritten label, most probably by André (" Dolerus lucens André (typ.)", Fig. 12I ) and its penis valve is dissected, another syntype male (the right forewing and flagellum missing) is selected as the lectotype because it is deposited in André’s collection (in ZIN), with many other type specimens of species described by him.

The holotype female of D. sanguinicollis var. reicherti has reddish lateral mesoscutal lobes and median mesoscutal lobes only slightly reddish on the anterior part, but according to the other diagnostic characters mentioned above, it belongs to D. fumosus .
