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 13–30 mm.
Distribution. Afrotropical Region.
