Mycale (Grapelia) burtoni Hajdu, 1995: 84, figs 6.34–37

Summary description (after Hajdu 1995). Of this species only a thick section slide, serving as the holotype, is so far known, limiting the information on spicule detail. There is a dense tangential ectosomal skeleton of intercrossing megascleres and numerous rosettes. Choanosomal spicule tracts comparatively stout, up to 230 µm in diameter. Spicules mycalostyles, robust, fusiform, narrowing to thin barely developed heads, 387–514 x 12–19 µm, anisochelae I curved, with short non-unguiferous upper alae, 83–94 µm, anisochelae II similar in shape to anisochelae I, 21–28 µm, anisochelae III, spurred, palmate, 15–21 µm, sigmas, thin, 26–37.
