Pedionis ( Pediopsis )

Key to male species of subgenus Pedionis ( Pediopsis) View in CoL (modified from Li et al., 2011)

Note. The species P. (P.) oeroe from Australia should belong to the subgenus Pedionis because the tegmina have only 2 subapical cells according to the original description, but the male genitalia have not been illustrated ( Kirkaldy 1907); therefore, this species is excluded from the key.
