Baetis purpurascens F.-J. Pictet, 1843 -1845: 174-175, pl. 20, fig. 4.

Heptagenia venosa ( Fabricius, 1775) . – Eaton, 1871: 151 (synonymization).

Ecdyurus venosus ( Fabricius, 1775) . – Eaton, 1888: 302 (transfer).

Ecdyonurus venosus ( Fabricius, 1775) View in CoL . – Ulmer, 1920b: 136 (transfer).

Accepted name: Ecdyonurus (Ecdyonurus) venosus ( Fabricius, 1775) View in CoL .

Locus typicus: “… au bord de la petite rivière de Viaison derrière le mont Salève”.

Type material: Holotype [by monotypy], female imago, not in MHNG.

Remarks: The description was obviously based on a single female and the taxon was considered by F.-J. Pictet to be closely related and very similar to Baetis venosa Fabricius, 1775 , except for some differences in colouration. No material could be traced and the name Baetis purpurascen s F.-J. Pictet can be considered a well-established junior synonym of Ecdyonurus venosus , a species widespread in Europe.
