Amauropsis aureolutea is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae, the moon snails. ^[1]

Description

The maximum recorded shell length is 32 mm. The minimum recorded depth is 6 m, while the maximum recorded depth is 662 m. ^[2]

(Original description in German) The shell is orange-brown in color. It is more spherical in contrast to the more rhomboid-rounded contour of Amauropsis anderssoni . The umbilicus is concealed by a protruding tongue of the columellar overhang. The apex features a larger nucleus than that of A. anderssoni, though the operculum remains the same.

The sculpture consists of growth lines and a faint, somewhat irregularly arranged, dense grooving. The suture lacks a compressed zone. ^[3]

Distribution

This marine species occurs off the Falkland Islands, South Georgia, South Sandwich islands and in the Southern Ocean.
