description: <i>Prosuberites carriebowensis</i> Rützler, Piantoni, van Soest &amp; Díaz, 2014 Tables 6, 7; Figs. 8A–B, 16G <b>Synonymy and references:</b> <i>Prosuberites carriebowensis</i> Rützler <i>et al</i>. (2014: 41), and van Soest (2017: 120). <b>Type locality.</b> Belize <b>Material examined.</b> CNPGG-2238, Triangulo Oeste reef (20.96221°N, - 92.31128°W), 16 m depth, coll. Julio Duarte, 08 September 2017; CNPGG-2211, Cayo Arcas reef (20.20183°N, - 91.97583°W), 6.9 m depth, coll. Diana Ugalde, 20 August 2018. <b>Description.</b> Thinly encrusting habit (Fig. 16G), the larger specimen measures 1.5 × 0.8 × 0.1 cm. Surface irregular and hispid with elevated oscules, covered by a translucent membrane. Orange color <i>in vivo</i>, yellowishorange preserved in ethanol. Consistency difficult to discern, highly delicate. <b>Skeleton.</b> Hymedesmioid skeleton type, tylostyles arranged vertically with their heads positioned into the basal spongin plate—no ectosomal specialization (Fig. 8A). <b>Spicules.</b> Megascleres: tylostyles in two size categories (Fig. 8B). Large tylostyles slightly curved to very curved shaft, with a small head, clearly set off, in a large size range, 350– <i>880</i> (449.1)–1800/10– <i>12.4</i> (2.5)–18 µm, tyle thickness 12– <i>15.7</i> (2.6)–20 µm. Small tylostyles, also large, but slightly thicker than the previous category, 200– <i>536.7</i> (241.6)–920/6– <i>15.8</i> (4.1)–20 µm, tyle 9.6– <i>20.6</i> (4.3)–24 µm thick. <b>Distribution.</b> Mexico (current records), Belize (Rützler <i>et al.</i> 2014). <b>Remarks.</b> Our material shows similarities with the original description of <i>P. carriebowensis</i> by Rützler <i>et al</i>. (2014); <i>viz</i>., thinly encrusting habit, irregular surface (slightly rugose) with dispersed and slightly elevated oscules, presence of translucent membrane over the surface, and orange color <i>in vivo</i>. However, the specimens described here have slightly larger and thinner tylostyles; viz., our material with 350–1800/10–18 μm (larger tylostyles) and 200–920/6–20 μm (small tylostyles) vs. material of Rützler <i>et al</i>. (2014) 240–840/15–30 μm (type I) and 230– 1550/9–25 (type II). Besides, we observe a simple hymedesmioid architecture from most of our material’s skeleton, while Rützler <i>et al</i>. (2014) have described bunches of tylostyles. This study presents the first record of <i>Prosuberites carriebowensis</i> for the GoM. <b>Order Axinellida Lévi, 1953</b>
