Original description: Macrosphère (80µm) grêle, avec trabécules internes toujours nets. Une seule coque corticale (145µm) grillagée, portant un nombre variable, mais toujours important de spicules tricarénés, puissants, généralement dentés, branchus ou non, les branches non disposées en verticilles. Ces spicules s'insèrent sur la coque externe par trois piliers en forme d'arc. Portion des spicules unissant C1 à C2 toujours grêle. Capsule centrale lobée ou sphérique, selon qu'elle présente ou non un diamètre supérieur à celui de C2. Une seule espèce.


Translated description: Macrosphere (d=80µm), thin, with internal trabeculae always clearly observed. A single cortical shell (d=145µm), lattice, bearing a variable number (always important) of three-sided radial beams, strong, usually dentated, ramified or not, their branches never grouped in verticils. These radial beams are inserted on the cortical shell by three arches. Beam interval between C1 and C2 always slender. Central capsule lobate, or spherical, depending on a diameter greater than C2.
