Characters of Eopolymitarcys of unclear phylogenetic status. (1) In cubital field of fore wing [see Polymitarcys/f1=Ephoron/g2 (5)] usually only one concave intercalary is present; it goes parallel to CuA toward tornoapical margin; sigmoid veins arise from this intercalary and directly from CuA (Kluge 2004: Fig.78:A). In selected specimens there are two or none intercalaries (in the last case all sigmoid veins arise from CuA). Non-unique character (see Index of characters [2.2.51] and [2.2.52]). (2) Egg has 2 polar caps [see Polymitarcys/f2=Ephoron/g3 (5)]. |
Size. Fore wing length 10–14 mm.
Distribution. Palaearctic.
