Callyspongia (Callyspongia) View in CoL sp.

( Fig. 34 View FIGURE 34 A–F) ( Tab. 15)

Examined material. Sample YO-257: Hawai’i, O’ahu Island, 30 m, 0 3 May 2005; YO-257-4, YO257-5: Hawai’i, O’ahu Island, depth ~ 30 m, 5 July 2007.

Description. Elastic and compressible sponge, about 3 mm thick, covering three fragments (about 7 cm long) of Carijoa riisei ( Fig. 34 View FIGURE 34 A), but not the anthocodiae ( Fig. 34 View FIGURE 34 B). Surface smooth, with incorporated sand. The sponge is deep orange ( Fig. 34 View FIGURE 34 A), and gray-pale yellow in ethanol.

Skeleton. The ectosome consists of a regular reticulation of polygonal meshes ( Fig. 34 View FIGURE 34 C, D) of primary, paucispicular fibres (about 20 μm in diameter), secondary paucispicular fibres (about 15 μm in diameter) and tertiary fibres often aspicular (5–10 μm in diameter). The choanosome is a regular reticulum of primary and secondary fibres producing polygonal meshes ( Fig. 34 View FIGURE 34 E). Primary fibres are plurispicular, about 45–65 μm in diameter, running to the surface and creating small conules ( Fig. 34 View FIGURE 34 D). Secondary, paucispicular fibres (about 20–35 μm) connect the primary fibres ( Fig. 34 View FIGURE 34 D).

Spicules. Vestigial oxeas, fusiform and slightly curved ( Fig. 34 View FIGURE 34 F), with black axial canal visible with microscopic examination, 47.5 – 87 x 2 µm.

No microscleres.

Remarks. This species of Callyspongia is characterised by the reduced thickness of the oxeas, always 2 μm. No species belonging to the subgenus Callyspongia has been recorded from Hawai’i (van Soest et al. 2011). Callyspongia (C.) serpentina Lamarck, 1814 is very similar to our Hawaiian specimens but the thickness of its oxeas is more variable (up to 6 μm) and primary and secondary fibres of the choanosome are very thin (about 25 μm in diameter) ( Wiedenmayer 1989).
