Formerly included in savii, but see Horácek et al. (2000). Both coreensis (see Horácek et al., 2000) and velox (see Corbet, 1978) have been treated as valid subspecies. Yoshiyuki (1989) treated coreensis as a distinct species. Note that we have corrected the spelling of the species epithet (from alaschanicus to the original alashanicus).
