Autapomorphy of Leucrocuta/fg2. (1) Male eyes are diminished and separated dorsally by 4–5 times width of median ocellus (Flowers 1980: Fig.20) (unlike majority of other Heptagennota and other mayflies, where male eyes are larger and separated dorsally by width of medial ocellus or less). Non-unique apomorphy: in selected species of various taxa (including some Ecdyonurus/fg1, but not Ecdyogymnurus or Afghanurus/g2) eyes are also diminished and widely separated. |
Size. Fore wing length 5–10 mm.
Distribution. Nearctic.
