| 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.
