Description The length of the shell attains 4.6 mm, its diameter 2 mm.
(Original description in German) This new species, which is represented by only two specimens, shows a great similarity and relationship to Pseudodaphnella rubroguttata (H. Adams, 1872).
The shell consists of eight whorls, the first three of which form a distinct brown apex. This apex is followed by a single whorl of white color, and only after this does the main part of the shell follows, decorated with a dark or reddish-brown coloration.
In this section, the nodes—which are formed at the intersection points of the three longitudinal (spiral) ribs and the transverse ridges—are alternately colored white and reddish-brown. The outer lip of the aperture bears an incision at the top. The aperture is less than half as high as the entire shell. Sturany, R. "Gastropoden des Rothen Meeres.

Distribution This marine species occurs in the Red Sea.
