Autapomorphies of Atalophlebopectinata.
(1) On maxilla [lacking canines – see Atalophleboadentata (1)] the proximal dentiseta is distinctly pectinate, i.e. bears a row of large spines on one side; dentiseta is directed apically and its denticles are directed medially. Distal dentiseta, if developed (in Habrophlebia/fg1 and Terpides/fg1 only), is non-pectinate, also directed distally, with apex arched medially (Kluge 2009: Fig.1). In some taxa with specialized maxillae proximal dentiseta is modified or lost (see Index of characters [1.1.39])
(2) Dorsal surface of labrum has two transverse rows of setae. In Habrophlebia/fg1 anterior row is regular, posterior row represents a transverse stripe of irregularly situated setae; in various Atalophleboculata anterior and posterior rows are often regular, sometimes irregular or lost (see Index of characters [1.1.14]).
Size. Fore wing length 2–15 mm.
