2-4mm long alive. Bright yellow with microscopic white specks. The siphonal crest is black and the edge of the upper part of the siphon can also be black. The posterior flagellum is black. They swim when disturbed. Gosliner distinguishes it from other species of the genus in having a terminal rather than a lateral flagellum on the posterior visceral hump.
