Remarks

Alycaeus summus is identical to A. otiphorus , therefore the former is a junior synonym of the latter. Unlike other members of this species group, A. otiphorus has a rather conical shell (instead of conical-globular), but it is classified here due to the expanded and reflected outer peristome.
