Accepted name: Ephoron savignyi (F.-J. Pictet, 1843).

Locus typicus: “Haute Egypte ”.

Type material: Holotype [by monotypy] female subimago, not traced.

Remarks: F.-J. Pictet briefly mentioned this species in the addenda of the genus Palingenia , saying he had not seen any specimens and based his diagnosis on the drawing provided by Savigny (of a female subimago), in accordance with article 12.2.7 of the International Code on Zoological Nomenclature (International Commission of Zoological Nomenclature, 1999). However, Eaton (1871) mentioned that several specimens were kept in F.-J. Pictet’s collection, and that later F.-J. Pictet gave him a specimen ( Eaton, 1883). In the MHNG two specimens are still present: a male imago ( Fig. 3 ), 620 48 Egypte coll. Pictet / Savignyi Pict. [purple label broken in four pieces], and a male imago, 620 48 Egypte coll. Pictet / M. De Selys Longchamp. None of them can be considered as type material. The type material should be in Savigny’s collection in the National Museum of Natural History in Paris, but a recent visit by the first author failed to find it. However, this is of no consequence for the validity of the species name (see International Commission on Zoological Nomenclature, 1999: article 73.1.4).
