Tables 6, 7; Figs. 48A–B , 58C

Synonymy and references: Fibulia bermuda de Laubenfels (1950: 52) ; Ulosa bermuda Rützler (1986: 121) ; Fibulia aff. bermuda and S trongylacidon aff. bermuda, Muricy et al. (2011: 190) ; Strongylacidon bermudae, Menegola et al. (2011: 4) ; Strongylacidon bermuda: Ugalde et al. (2015: 163) .

Type locality. Bermuda .

Material examined. CNPGG-2170, Cayo Arcas reef (20.19491°N, 91.95741°W), 10 m depth, coll. Diana Ugalde, 25 April 2018 .

Distribution. Mexico ( Ugalde et al. 2015; current records), Bermuda (de Laubenfels, 1950) .

Remarks. Strongylacidon bermuda has previous records from Bermuda; viz., de Laubenfels (1950); as Fibulia bermuda , and Rutzler (1986); as Ulosa bermuda . It has recently been recorded for the SGoM by Ugalde et al. (2015), particularly in Alacranes reef, at 5 m depth. Apparently, it is relatively common in Bermuda, but it is rare in the GoM and was never recorded previously in the Caribbean Sea. It is certainly a shallow-water species since all previous species’ records were taken at 3–5 m depth. The current record is from 10 m.
