Original description: Shell large, fairly wide, dome-shaped, and smoothsurfaced or slightly tuberculate, with a slender rodlike apical horn and 7-10 slender basal feet. Shell divided by a median vertical constriction; the pores small, circular to subcircular, irregular in size and arrangement. Internally the basal structure is rather delicate, and has six basal pores.

(Based on 10 specimens) Maximum width of shell 134-164 µ and height of shell 80-110 µ. Distinguishing characters (rw): This species differs from Dendrospyris inferispina Goll (1968, p. 1421, pl. 174, figs. 5-8, 10) and Dorcadospyris platyacantha (Ehrenberg) in having a rather large and laterally wide shell, and the wall perforated with a great number of small pores, and in having short terminal feet.
