Descriptions

In 1968 Dragesco described and additional species of Discocephalus from sands of Arcachon: D. minimus. This species is cephalized, possesses right and left marginal cirri (the left marignal cirral row is differentiated into an anterior set of 7-8 cirri and a posterior set of 9-10 cirri), 2 midfrontal cirri, and 7 transverse cirri. Four additional cirri, posterior to the 4-6 right marginal cirri probably represent groups of caudal cirri. Seven additional frontal (one probably a paroral cirrus) are present in the cephalized region. Membranelles extend only to the anterior of the cell. Three to fifteen spherical macronuclei are scattered throughout the cytoplasm. (ref. ID; 7679)
