Overlooked but not forgotten: the first new extant species of Hawaiian land snail described in 60 years, Auriculella gagneorum sp. nov. (Achatinellidae, Auriculellinae).

ABSTRACT: Recent surveys of Oahu's Waianae Mountains uncovered a small, previously undescribed species of Auriculella that is conchologically similar to the three members of the A. perpusilla group all of which are endemic to the Koolau Mountain Range. However, sequence data demonstrate that the perpusilla group is not monophyletic. Moreover, the new species is not closely related to A. perpusilla or A. perversa, the only extant members of the group, but instead is sister to A. tenella, a species from the high spired A. castanea group. A neotype is designated for A. auricula, the type species of Auriculella; all members of the conchologically similar perpusilla group are anatomically redescribed; and lectotypes designated for A
