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.
