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 916 mm.

Distribution. Eastern Nearctic and Japan.
