Characters of Protephemeroidea of unclear phylogenetic status.

(1) On wings of both pairs RS is basally fused with RA and independent from MA (Kluge 2004: Fig.14:A) (unlike Euephemeroptera).

(2) RSa2 is non-branched (probably on wings of both pairs, but for certain known for hind wings only – Kluge 2004: Fig.14:A) (unlike many Euephemeroptera).

(3) MA is non-branched (Kluge 2004: Fig.14:A) (unlike majority of Euephemeroptera).

Size. Fore wing length more than 21 mm.

Age. Carboniferous (France).

Nominal species in Protephemeroidea: 1 species
