Diagnostic characters. Pima is characterized by the male basal few flagellomeres shallowly incurved and containing a row of minute, tooth-like spines (Figs 1a, 2a), third segment of the labial palpus projected forward (Figs 1b, 2b); the forewing usually having a white subcostal streak (absent in P. keredjella, P. milka, P. parkerella, P. pempeliella, P. transfusor and P. tristriata sp. nov.), with 11 veins (Figs 1c, 2c), R2 approximate to the stalk of R3+4 + R5, R3+4 stalked with R5 of less than half their lengths, M2, M3 and CuA1 free; the hindwing with 10 veins (Figs 1c, 2c), Rs and M1 shortly stalked, M2 and M3 stalked for over half their length, CuA1 and M2+ M3 shortly stalked; apical process of gnathos short and stout, transtilla absent, the broad costa of the narrowed valva with a blunt, slightly forked apex (more pointed and not forked in P. christophori, P. leucoloma, P. pempeliella, and P. trifidella), the uncus with a broad base and a short pair of lateral lobes, the aedeagus with two stout cornuti (one cornutus in P. trifidella) in male genitalia (Figs 3, 4); the ductus bursae ribbon-like, the stout corpus bursae scobinate-granulate and usually with sclerotized patches or folds in female genitalia (Figs 5, 6).

Pima resembles Epischnia Hübner, but they can be separated by the following characters: in Pima, the male flagellum with a row of tooth-like spines near the base, the labial palpus with terminal two segments approximately of equal length; male genitalia with a broad, apically slightly forked costa, and two stout cornuti in the aedeagus; female genitalia with a strongly sclerotized, funnel-shaped antrum, the corpus bursae scobinate-granulate throughout and with sclerotized patches or folds. Whereas, in Epischnia, the male flagellum lacks a tooth-like spine, the third of the labial palpus is less than half the length of the second; the costa is weak and not forked at the apex, and the aedeagus has a bunch of spinules in the male genitalia; the antrum is weak or represented by a band-shaped plate, the corpus bursae is smooth on the inner surface except for one big sclerotized plate or a line of small thorns and one bunch of spinules in the female genitalia.
