Aegires ninguis Fahey and Gosliner, 2004Distribution: Reported from temperate Atlantic and Indian Oceans of South Africa.
This new species can be identified by the white to pale yellow background color and minute white speckles on the dorsum between the tubercles. The tubercles are short and rounded. There are no tubercles on the posterior end of the foot. On the anterior of the head region, there are two prominent tubercles with smaller tubercles between them. Between the rhinophores there are also two prominent tubercles. Numerous spicules protrude from the dorsal tubercles such that they appear fuzzy. The rhinophore sheath is slightly elevated and has five papillae on all sides except the innermost. The gill is protected on the anterior side by extra-branchial papillae that are tri-lobed. The rhinophores are pale yellow on white specimens and deeper yellow on the yellow specimens. The gill branches match the background color in all specimens examined. The specimens found in South Africa range from 6–8 mm in length.
