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. minuta, A. perversa, and A. tenella. The new species is described and compared to the type of the genus, members of the perpusilla group, and the genetically similar species A. tenella.

被忽视但没有被遗忘：60 年来描述的第一个新的夏威夷陆生蜗牛物种，Auriculella gagneorum sp。十一月 （蝾螈科，木犀科）。

最近对瓦胡岛怀厄奈山脉的调查发现了一种以前未被描述过的小木耳属，它在贝壳学上与 A. perpusilla 组的三个成员相似，所有这些成员都是库劳山脉的特有种。然而，序列数据表明 perpusilla 组不是单系的。此外，新物种与 A. perpusilla 或 A. perversa（该组的唯一现存成员）没有密切关系，而是 A. tenella 的姐妹，后者是来自高尖 A. castanea 组的物种。A. auricula，Auriculella 的模式种，指定了一个新型；在解剖学上重新描述了贝壳学上相似的 perpusilla 组的所有成员；和指定用于 A. minuta、A. perversa 和 A. tenella 的选型。新物种被描述并与属的类型进行比较，
