Character of Eatonica/g2 of unclear phylogenetic status.

(1) Imaginal and subimaginal gonostylus with 1 distal segment only (instead of two initial ones). Non-unique apomorphy (see Index of characters [2.3.12]); among Ephemera/fg9 the same in Eatonigenia (possibly synapomorphy) and Pseudeatonica.

Plesiomorphies of Eatonica/g2. Larval claw of fore leg is normally developed (unlike Eatonigenia). Vestige of tergalius I [see Ephemera/fg9 (4)] is bilamellate (unlike Litobrancha). Penis has no shape peculiar for Eatonigenia.

Size. Fore wing length 1330 mm. 

Distribution. Afrotropical Region.
