Species Description:
Eyes present, cuticle smooth. The buccal and the pharyngeal tube are very narrow (diameter about 1 micron). Pharynx oval, with length-width ratio of 1.3~1.4:1, but sometimes almost spherical, containingobvious apophyses, 3 macroplacoids of granular shape or even of short rounded rods, increasing in length from 1st to 3rd, and small microplacoid. Exuvia have been observed with one egg. For distinction from D. alpinum (very uncertain), from D. chilenense, and from D. tenue we refer the reader to that said under the description of D. alpinum. As of 1983, D. stappersi has been found only on the Spitsbergen Islands and on Orsi Island.
