Mexico (Gómez 2007, 2011; De la Cruz-Francisco & Bandala-Pérez 2016; current records), Bermuda (de Laubenfels 1950), Bahamas, US (Florida), other countries in the Caribbean Sea, Brazil (Muricy et al. 2011). Remarks. Spirastrella is characterized by possessing tylostyles in a variety of lenghts and spirasters of one or more types, in some cases with bifurcations in their rays. However, the length in both the spirasters and tylostyles overlapp among species, which complicates species identification. The two species have three spirasters that differ in S. coccinea for being larger than in S. mollis. Although the tylostyles are similar in length in both species, in S. coccinea they are thinner than in S. mollis. Spirastrella coccinea is a common species in the coral reefs of the GoM; it was previously recorded from the Veracruz Reef System (Gómez 2007, 2011), and now from different coral reefs at the Campeche Bank, and additional materials from the Veracruz Coral Reef System., Published as part of Ugalde, Diana, Fernandez, Julio C.
