Leucosolenia sp.
Material examined. MNHN DCL 4042–D, Jean-Louis Etienne Expédition Clipperton 2005, station 18, 55 m, on dead corals, 20–01–2005, 1 specimen.
Description. Tiny, holllow, lobate branches of less than 0.5 mm diameter. The spiculation consists of triactines both regular and sagittal, with rays varying from 18 x 1 µm to 90 x 3 µm; tetractines fairly uniform in size, facial rays 60– 66 x 2–3 µm, apical rays shorter, 10–20 µm; oxeas in two distinct size classes 165–270 x 6 µm and 75– 90 x 1–2 µm. A peculiar feature are triactines with strongly curved or hooked ray endings protruding beyond the surface.
Remarks. The material is insufficient to characterize properly against the many described Leucosolenia species.
