Original description: Cephalis externally obtusely cap-shaped, generally separated from the thorax by a slight change in contour. Thorax barrel-shaped, with smooth surface and circular pores longitudinally aligned. Lumbar stricture expressed externally by a distinct change in contour. Abdomen subcylindrical, hyaline, usually with one row of pores proximally and a row of teeth terminally.

(Based on 25 specimens) Total length 115 to 190µm. Maximum breadth 80 to 105µm. Distinguishing characters (rw): This species is distinguished from C. favosum by the more pronounced longitudinal alignment of the thoracic pores, and by the abdomen being always sub-cylindrical.
