Stelletta anthastra n. sp. (Fig. 3) Material examined. Holotype, USNM 1231429, in 70% ethanol, fragment of the holotype (ZSM 20140114), in 70% ethanol. Collected by Brian Knoth with a research survey bottom trawl from the FV Ocean Explorer; 17 June 2012, 225 m depth, 19.8 km WNW of Carlisle Island in the Islands of Four Mountains, eastern Aleutian Islands, Bering Sea (52°58.542” N, 170°23.322” W). Attached to a mass of sand and pebbles. Bottom water temperature = 3.9 °C. Description.
