Distribution. Mexico ( Gómez 2007; De la Cruz-Francisco & Bandala-Pérez 2016; current records), Bermuda, Bahamas, US (Florida), Cuba, other countries in the Caribbean Sea ( Rützler et al. 2014); Brazil ( Muricy et al. 2011).

Remarks. Scopalina ruetzleri has been reported in the northern ( Rützler et al. 2009) and the SGoM ( Gómez 2007). Although we have only collected material from reefs (Cayo Arcas reef and Madagascar reef), this species is a common one along the coral reefs in the Campeche Bank: Triangulos reef, Obispo reef, Alacranes reef, and Cayo Arenas reef.
