Description
The length of the shell attains 10 mm, its diameter 12 mm.
The protoconch has no particular sculpture and is rather matte. The upper spire shows low, irregular growth ridges. The rest of the spire is relatively short, but much longer than typical in Stomacosmethis. The surface is irregularly wrinkled, and possibly ribbed near the suture.[2]
