Material examined and sequenced PAPUA NEW GUINEA • 1 lv; Manus I; 02°10′ S, 147°16′ E; 200–219 m deep; BIOPAPUA; stn DW3694; GoogleMaps

MNHN IM-2013-63891.

Remarks

Radula (n =1, Fig. 20A View Fig ) with tricuspid central tooth, with medium broad lateral flaps, central cusp 1.5 times narrower and shorter than lateral ones. Cusps nearly smooth, while lateral flaps are strongly serrated with shallow longitudinal grooves situated between cusplets. 1–2 additional minute cusplets on both sides of central cusp.

In the molecular tree, this seemingly subadult specimen was recovered as sister to Amalda cacao sp. nov. In shell appearance it resembles a miniature A. hilgendorfi , although with thinner and uncarinated spire callus, which is much less microshagreened than in A. hilgendorfi . Judging from the molecular tree, this specimen clearly represents a new species, but we abstain from description pending the collection of additional material including adult specimens.
