Baetis montana F.-J. Pictet, 1843

Baetis montana F.-J. Pictet, 1843 -1845: 172-173, pl. 20, fig. 3.

Heptagenia montana . – Eaton, 1871: 154 (transfer).

Heptagenia montana . – Eaton, 1888: 302 (species of uncertain generic placement).

Accepted name: Baetis montana F.-J. Pictet, 1843 nom. dub.

Locus typicus: “… petit ruisseau qui descend du Brévent au-dessus de Chamounix”.

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

Remarks: F.-J. Pictet gave a very brief description of this alpine species. Eaton (1888) was unable to place it with certainty among the Heptageniidae . No original material of this taxon could be traced. In the MHNG there is one female imago with the following label data “620 Burgdorf 48 coll. Pictet / Baetis montana P. Bgdf 9 Juni”, obviously a specimen collected and identified by Meyer-Dür and most probably belonging to the so called Ecdyonurus helveticus species-group. The name Baetis montana F.-J. Pictet, 1843 should be considered a nomen dubium (see also Haybach, 2010).
