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 ).
