Autapomorphy of Eurylophella/fg2. (1) Larval abdominal segment IX is elongate: medially it is approximately 1.4 times longer than segment VIII (Kluge 2004: Fig.91:I). Non-unique apomorphy, the same in many Ephemerella/fg3 and some other Ephemeroptera; in other Timpanoga/fg1 abdominal segment IX is subequal or only slightly longer than segment VIII. Character of Eurylophella/fg2 of unclear phylogenetic status. (2) Egg without polar cap (unlike majority of other Ephemerella/fg1, which have one polar cap), with polygonal relief, without anchors [see Ephemerella/fg1 (14)]. It is unclear if this is an autapomorphy of Eurylophella/g2 or Eurylophella/g1, as egg structure of Dentatella is unknown. |
Size. Fore wing length 6–11 mm.
Distribution. Mainly Nearctic, also in Europe.
