Tables 6, 7; Figs. 41A–G , 45H

Synonymy and references: Clathria foliacea Topsent (1889: 39) , Hooper (1996: 173), and Gómez (2014: 53); Clathria ( Clathria) foliacea , and Thalyseurypon foliacea : see references compiled in Hooper (1996: 173), and Gómez (2014: 53).

Type locality. Campeche Bank , Mexico .

Material examined. CNPGG-2172, Cayo Arcas reef ( 20.199083°N, 91.96380°W), 10 m depth, coll. Diana Ugalde, 25 April 2018 .

Distribution. Mexico ( Topsent 1889; Gómez 2014; current records), US ( Florida) (de Laubenfels 1936 as Thalyseurypon foliacea ).

Remarks. Clathria ( C.) foliacea is a shrub shaped sponge, pedunculate or not, the branchlets mainly flabellated, similar in shape to C. ( C.) carteri (not represented in this study). Therefore, light microscopy for spicule definitions is necessary to confirm the proper identification. Clathria ( C.) foliacea has been reported and described for both the SGoM ( Gómez 2014) and northern Gulf (de Laubenfels 1936, as Thalyseurypon foliacea ).
