Autapomorphies of Hyrtanella/f1=Torleya/g1. Distinct autapomorphies are unknown. The features listed here, are characteristic for Torleya/g1, while can not serve as diagnostic to separate Torleya/fg1 it from Ephemerella/fg4. (1) Maxillary palp is usually smaller than in majority of Ephemerella/fg3, often lost [see Ephemerella/fg1 (1)]. (2) Larval caudalii often (but not always) with whorls of heavy spine-like setae on posterior margins of segments, and often (but not always) without swimming setae. Plesiomorphy of Hyrtanella/f1=Torleya/g1. Unlike Ephemerella/fg4, ventral lobe of tergalius VI is bifurcate (Kluge 2004: Fig.91:B), as that of tergalii III–V [see Ephemerella/fg3 (1)]. |
Size. Fore wing length 4–10 mm.
Distribution. Holarctic and Oriental Region.
