Description. Open network of creeping and upright tubuli, covering the surface of a keratose sponge ( Hyrtios  sp.) ( Fig. 26aView FIGURE 26), size several cm2. A second specimen ( Fig. 26aView FIGURE 26 1View FIGURE 1, not collected) encrusted an ascidian. Individual tubuli approximately 2 mm high and 1 mm diameter. Upright tubuli often open-ended, presumed to be oscules. Color shades of dull orange, pink-orange and beige; pale beige in preservation ( Fig. 26bView FIGURE 26).

Aquiferous system. Asconoid.

Skeleton. ( Fig. 26cView FIGURE 26) Walls of tubuli with a single layer of spicules.

Spicules. ( Fig. 26dView FIGURE 26) Triactines with conical actines, variable in length, 66– 97 –129 x 6 – 7.4 –9 µm.

Distribution and ecology. Maldives, coral reef, 10 m.

Etymology. Repens (L.) means creeping, referring to the reticulation of small tubuli closely adhering to the substratum.

Remarks. Morphologically, this appears a unique species. Its habitus and spicule sizes show similarity to Indonesian Arturia tubuloreticulata Van Soest & De Voogd, 2015  , but this has a minority of tetractines. We examined the present specimen exhaustively, but could find no tetractines.

Unfortunately, no sequences were obtained from it.
