Caenis grisea F.-J. Pictet, 1843

Caenis grisea F.-J. Pictet, 1843 -1845: 278-279, pl. 45, figs 1-2. Caenis macrura ( Stephens, 1836) View in CoL . – Eaton, 1871: 93 (synonymization). – Malzacher, 1986: 15.

Caenis halterata ( Fabricius, 1777) . – Eaton, 1885: 145 (synonymization).

Accepted name: Caenis macrura ( Stephens, 1836) View in CoL .

Locus typicus: “… dans un petit marais situé au pied du mont Salève”.

Type material: Syntypes ( male imago and subimago), not traced and most probably lost.

Remarks: In the MHNG there is one specimen (female subimago) which bears the name Caenis halterata Fabr. and originates from Burgdorf (coll. Meyer-Dür). This specimen belongs to Caenis luctuosa ( Burmeister, 1839) . Without any new available data, we accept the synonymy proposed by Eaton (1871) and followed by Malzacher (1986), but in our opinion C. grisea could also be considered a junior subjective synonym of C. luctuosa ( Burmeister, 1839) .
