Errina argentina Bernal, Cairns & Lauretta, 2018 in Bernal et al. 2019

Distribution. Mar del Plata Submarine Canyon and adjacent area, 1398 m depth.

Material examined. MACN-In 41480 (holotype) off Mar del Plata , Argentina, St. 59 (37º 49.688’ S, 54º 5.236’ W), 1398 m, September 2013 ; MACN-In 40652 off Mar del Plata , Argentina, St. 59 (37º 49.688’ S, 54º 5.236’ W), 1398 m, September 2013 .

Description. See Bernal et al. 2019

Discussion. Hitherto there are only two species (and possibly a third species, should Errina sp. be confirmed as a new one) of this genus described from off Argentina: E. antarctica (Gray, 1872) and E. argentina . There are probably more species of Errina to be discovered in the study area, considering there are several stylasterid species in common between SWA off Argentina and the circumantarctic zone (see Discussion section).
