Autapomorphies of Prionoides. (1) Penis dorso-laterally with a pair of projections curved medially and bearing sclerotized denticles or spines (Kondratieff & Woshell 1983: Fig.1-5). Similar penis structure independently evolved in Pentamerotarsata (see below). (2) Egg [see Branchitergaliae (4)] has shape of biconvex lens (Kondratieff & Woshell 1983: Fig.17-20) (unlike spherical in Isonychia/fg2). Non-unique apomorphy; the same in some species of Ameletus/fg2. Plesiomorphy of Prionoides. Unlike Isonychia/fg2, styliger is well-developed, median emargination between gonostyli pedestals being shallow (Kondratieff & Woshell 1983: Fig.1). |
Size. Fore wing length 9–16 mm.
