Sarà and Siribelli, 1960

Species Overview

Timea stellifasciata Sarà and Siribelli (1960) is a thin brownish encrustation with slightly hispid surface and firm consistency. It differs from other Timea species in the irregular morphology of the asters (microscopic examination). It is a Mediterranean species recorded once from Roscoff.

Taxonomic Description

Colour: Brownish or yellow-brown.
Shape, size, surface and consistency: Thin encrustation with slightly hispid surface and firm consistency. No further data.
Spicules: (Timea stellifasciata spics) Megascleres: Tylostyles, with variously shaped heads: 125-950 x 3-9 µm (Mediterranean specimens: up to 595 µm). Microscleres: Asters of extremely varied shape, but symmetrical equal-rayed asters absent, rays irregular, truncated or bifid, warty and strongly spined: 7-21 µm.
Skeleton: Tylostyles erect on the substrate; asters distributed throughout the sponge.
Ecology: Under stones, on other sponges, on pebbles, in deeper water (Roscoff: 55 m)
Distribution: Roscoff, Naples.
Etymology: The name refers to the concentrated occurrence of the asters.
Type specimen information: The holotype is stated to be in Stazione Zoologica di Napoli.

Remarks

In spiculation this species is close to Timea fasciata, but that species is golden yellow, and the asters are less irregular.
