Type locality. Florida .

Material examined. CNPGG-2228, Cayo Arcas reef (20.19566°N, 91.95997°W), 0.5 m depth, coll. Diana Ugalde, 23 August 2018 .

Distribution. Mexico ( De la Cruz-Francisco & Bandala-Pérez 2016, current record), Bermuda (de Laubenfels 1950) , Bahamas ( Wiedenmayer 1977), US (Florida, de Laubenfels 1936), other countries in the Caribbean Sea, Guyana, and Brazil ( van Soest 2017).

Remarks. Chondrosia collectrix has been found in several localities in northeastern Brazil and the Caribbean region ( Rützler et al. 2009; Muricy et al. 2011; van Soest 2017). Our specimen matches the description provided by

In our specimen, we were able to record the presence of oscules with an elevated collar in vivo, as remarked upon in Wiedenmayer’s (1977) description. According to van Soest (2017) C. collectrix should be reviewed due to morphological variability. Similarly, records of the Mediterranean C. reniformis Nardo, 1847 in the TNwA, also need reassessment.
