Xestospongia rosariensis is named from coral reef habitats of the Nuestra Señora del Rosario Archipelago in the Colombian Caribbean. This sponge is tube-shaped, brown in color, hard and brittle in consistency, and is provided with sinous surface irregularities. The dense skeleton reticulation of thick spicule tracts is typical for the genus. Spicules are oxea having mean dimensions of 183.6 x 9.4 µm. X. rosariensis has several affinities with X. subtriangularis, particularly the small dimensions of spicules.  Its distintive growth form makes the new species unmistakable among the members of Xestospongia.

De los habitat de arrecifes coralinos del Archipiélago de Nuestra Señora del Rosario en el Caribe Colombiano, se describe Xestospongia rosariensis.  Esta esponja es tubiforme, de color café, de consistencia dura y quebradiza, y su superficie tiene algunas irregularidades sinuosas. Su densa reticulación esquelética de tractos espiculares gruesos es típica del género. Las espículas son oxeas, con dimensiones promedio de 183.6 x 9.4 µm. X. rosariensis tiene algunas afinidades con X. subtriangularis, particularmente por el tamaño pequeño de las espículas. La típica forma de crecimiento de esta nueva especie la hace inconfundible entre los miembros de Xestospongia.
