Material examined. CNPGG-1351, Alacranes reef (22.3864°N, 89.6801°W), 9 m depth, coll. Diana Ugalde, 19 February 2012 GoogleMaps ; CNPGG-2190, Cayo Arcas reef (20.20512°N, 91.96305°W), 0.5 m depth, coll.

Description. Spherical habit ( Fig. 79C View FIGURE 79 ); overall size 1.8 cm in diameter by 1.2 cm high. The surface is hispid with a few porocalices scattered, 0.2 cm diameter. The color in vivo is yellow and beige preserved in ethanol. The consistency is slightly compressible.

Skeleton. Compact radial skeleton formed by tracts of oxeas ( Figs.73A–B View FIGURE 73 ). Cladomes of triaenes that reinforce the main tracts of oxeas protruding outside the surface. Sigmaspires throughout the whole skeleton.

Spicules. Megascleres: Large oxeas, straight, fusiform, and smooth ( Fig. 73 C View FIGURE 73 1 View FIGURE 1 ); 1595.5– 1865.9 (278.4)– 2112/14– 19.2 (6.4)–27.4 µm. Small oxeas, straight, fusiform, and smooth ( Fig. 73 C View FIGURE 73 2 View FIGURE 2 ); 850– 881.7 (27.6)–901/10– 10.1 (0.1)–10.2 µm. Large protriaenes, with broken rhabdomes (length was not measured; Fig. 73 E–F View FIGURE 73 ); 7.6– 9.6 (2.7)–12.7 µm thick. Clads; 75.4– 90.4 (19.6)–112.6/4.8– 6.2 (1.8)–8.2 µm. Anatriaene (n = 1; Fig. 73G View FIGURE 73 ), broken rhabdomes (length was not measured); 5 µm thick. Clads; 10/6 µm. Microscleres ( Fig. 73H View FIGURE 73 ): Microxeas, straight and microespined ( Fig. 73D View FIGURE 73 ); 100– 106 (5.3)–110/4.5–5 (0.5)–5.5 µm. Sigmaspires (Fig. H), 8– 9.6 (1.4)–12 µm in length.

Distribution. Mexico ( Gómez 2002; Gómez & Calderón-Gutiérrez 2020; current records), Bahamas, US (North Carolina, Florida), Cuba, other countries in the Caribbean Sea, and Brazil ( Cárdenas et al. 2009).

Remarks. The distribution of C. kuekenthali is similar to that of C. apion , ranging from the GoM to Brazil ( Rützler & Smith 1992; Rützler et al. 2009; Hajdu et al. 2011; Muricy et al. 2011; Fernandez et al. 2018). However, C. kuekenthali is also known from deeper waters, down to 100 m in Brazil ( Fernandez et al. 2018). It also inhabits Mexican caves, such as the anchialine cave La Quebrada, in Quintana Roo ( Gómez & Calderón-Gutiérrez 2020). Our material has the same set of spicules of known specimens of C. kuekenthali ( Rützler & Smith 1992; Hajdu et al. 2011; Fernandez et al. 2018). However, triaenes were rare, and microxeas were not abundant in our material.
