Baetis cerea F.-J. Pictet, 1843 -1845: 183-184, pl. 23, fig. 2.

Heptagenia flavipennis ( Dufour, 1841) . – Eaton, 1888: 273 (synonymization).

Heptagenia longicauda ( Stephens, 1836) View in CoL . – Kimmins, 1942a: 122 (synonymization).

Accepted name: Heptagenia longicauda ( Stephens, 1836) View in CoL .

Locus typicus: “… sur les bords du lac de Genève …”.

Type material: Holotype [by monotypy], male imago, not traced.

Remarks: In the absence of any specimen of this species in the MHNG, we follow the synonymy proposed by Kimmins (1942a). F.-J. Pictet (1843: 193) already noticed that B. longicauda Stephens, 1836 was closely related to his B. cerea .

Heptagenia longicauda is extremely rare in Switzerland, the last record from the lake of Geneva area is more than 30 years old ( Sartori & Dethier, 1985).
