Potamanthus geerii F. -J. Pictet, 1843

Potamanthus Geerii F. -J. Pictet, 1843 -1845: 211-214, pl. 26, figs 1-3.

Leptophlebia helvipes ( Stephens, 1836) . – Eaton, 1871: 85 (transfer and synonymization).

Leptophlebia submarginata ( Stephens, 1836) . – Eaton, 1884: 94 (synonymization).

Paraleptophlebia submarginata ( Stephens, 1836) . – Lestage, 1917: 344 (transfer).

Accepted name: Paraleptophlebia submarginata ( Stephens, 1836) .

Locus typicus: “J’en possède des exemplaires de l’Italie septentrionale, ... elle n’est pas rare aux environs de Genève …”.

Type material: Syntypes (male and female imagines, female subimago, larva), not traced.

Remarks: In the MHNG there is a series of Leptophlebia submarginata ; 3 specimens (1 male, 2 females) among them bear the label “ Potamanthus geerii L.”, but they originate from Burgdorf (ex. coll. Meyer-Dür) and have obviously been collected after the publication of the original description.

Note the obvious printing error in the original description (F.-J. Pictet, 1843: 211), attributing this species to Lin[naeus] instead of declaring it a new species.
