Of this species only a thick section slide, serving as the holotype, is so far known, limiting the information on spicule detail.

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.   Distribution.
