Pyrgiscus crenatus

Pyrgiscus crenatus is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.

Taxonomy
There is disagreement regarding whether Pyrgiscus rufus (Philippi, 1836) and Pyrgiscus fulvocinctus are different species (e.g. according to Peñas & Rolán in Gofas et al., 1999; Giannuzzi-Savelli et al., 2014; Høisæter, 2014) or the same species (e.g. van Aartsen, 1981). In the former case it cannot be determined to which of the two species corresponds the earliest name Pyramis crenatus Brown, 1827, which Høisæter treated as a nomen dubium.
