Synonymy: Schmidtia muta Schmidt (1870: 44) ; Petrosia muta : see references compiled in Muricy et al. (2011: 107–108); Xestospongia muta, Gómez (2002: 90) , Hajdu et al. (2011: 198), Muricy et al. (2011: 107–108), Pérez et al. (2017: 10) and van Soest (2017: 40) ―other references therein.

Type locality. Florida .

Material examined. CNPGG-2230, Cayo Arcas reef (20.19566°N, - 91.95997°W), 10.2 m depth, coll. Diana Ugalde, 24 August 2018 .

Distribution. Mexico ( Gómez 2002; Maas-Vargas 2004; current records), the Bahamas, US (Florida), other countries in the Caribbean Sea, Guyana, to Brazil ( van Soest 2017).

Remarks. Xestospongia muta has been reported in the northern GoM ( Rützler et al. 2009). Xestospongia muta was also quoted by Gómez (2002) at Yucatan; however, there is no specific location. Our records confirm the presence of the species in the Southern section of the GoM.
