Description
Summary:Latrunculia velera sp. nov. (Fig. 15 a–f, Fig. 16 a–d) Description Dark brown, subglobose sponge (Fig. 15 a) with a smooth, uneven surface. The surface is leathery, only slightly elastic, easily broken. There are small circular, slightly elevated oscules scattered over the surface. Areolate pore­fields are not present. The interior is markedly fibrous, somewhat similar to L. oparinae Samaai & Krasokhin, 2002, but differing slightly in shape and clearly in the absence of areolate pore­fields and the form of the anisodiscorhabds. The holotype was attached near its base to a cobble. Skeleton: The ectosome is a unispicular layer of discorhabds, all arranged with their longitudinal axis perpendicular to the surface. The choanosome is a reticulation of polyspicular tracts of styles with some anisodiscorhabds in between. Spicules: Megascleres are styles (Fig. 15 b) with slightly acanthose heads (Fig. 15 c), 500–540 x 9–11 µm. Microscleres are relatively smooth anisodiscorhabds (Fig. 15 e), 37–43 µm.
