Potamides archiaci is placed to the genus Potamides according to its shape, coiling pattern, and typical ornamentation.[1]
The shell is small, narrow, turreted and conical. The spire is high. The shell is widening slowly and the apical angle is small. The shell has about 15 depressed whorls, which are separated by prominently impressed sutures. The base of the shell is flat, and the aperture is elliptical. There are two prominent rows of spiral tubercles on the sculpture. The surface in the earliest whorls is marked only by a beaded angularity. Its posterior beads become stronger tubercles, and are more distantly spaced than the anterior beads.[1]
The width of the holotype is 5.9 mm, and its reconstructed height is about 24 mm. The maximum measured width of the shell is 8.05 mm, and its maximum reconstructed height is 31.22 mm.[1]
