Autapomorphies of Traverella/g1.

(1) Each tergalius I–VI has both lamellae [see Leptophlebia/fg1 (10)] wide, roundish-triangular narrowing apically, with numerous long slender processes on entire margin; tergalius VII either has similar structure but diminished, or is absent (Allen 1973: Fig.19–22). Similar tergalial structure is found in some other non-related taxa (see Index of characters [1.3.23]).

Size. Fore wing length 6–10 mm.
