Autapomorphy of Caudatella. (1) Larval, subimaginal and imaginal paracercus is much longer than (1.3–4 times) cerci (unlike other Ephemerella/fg2, whose paracercus is subequal to cerci). Plesiomorphies of Caudatella. Maxilla is biting [see Ephemerella/fg1 (16)]. Larval thorax without projections characteristic for Cincticostella/g1 or Notacanthella. Larval fore legs are non-grasping (unlike Drunella). |
Size. Fore wing length 6–12 mm.
