Material: 1 specimen in total. Anda2 (1) RGM 962136.

One adult specimen (OL= 4.1, OH= 3.6 mm) has been encountered. The rather round outline with clear middorsal angle, the shape of the sulcus, the weakly pronounced rostrum, and number of denticles (15) along the ventral rim suggest a close relation to the extant D. brachycephalus Tåning, 1928 .
