Remarks. There are two species of Erylus Gray 1987 recorded from the GoM. Erylus trisphaerus (de Laubenfels, 1953) described originally from Florida by de Laubenfels (1953) and recently recorded in the SGoM ( Ugalde et al. 2015), whose main characteristic is the trilobate aspidasters; and Erylus formosus Sollas, 1886 which has elongated aspidasters and microstrongiles instead of microxeas. For a detailed description, refer to Ugalde et al. (2015) and the references cited above.
