Autapomorphy of Polymitarcys/f3=Ephoron/g4.

(1) Cubital field of fore wing [see Polymitarcys/f1=Ephoron/g2 (5)] contains 35 intercalaries alternating as concave and convex; they go parallel to CuA toward tornoapical margin and tornus (Eaton 18831888: Pl.6:10a-c; Ishiwata 1996: Fig.1621) (unlike all other Polymitarcys/f1=Ephoron/g2 which have no more than two such intercalaries see Index of characters [2.2.51] and [2.2.52]).
