Chamalycaeus asaluensis (Godwin-Austen, 1914)

Chamalycaeus asaluensis View in CoL species group

Remarks

The species belonging here are characterized by a low conical, colourless shell, a strongly ribbed R1 (rib density relatively low), and an upper incision in the aperture. The aperture shape (fringed to circular) and the shape of R3 swelling are highly variable.

Some species of this species group have been classified in the genus Dicharax (see Páll-Gergely et al. 2020), because spiral striation could not be observed on them, partly because the examined shells were corroded, and partly because the spiral striation on the shells are naturally weak and difficult to observe.
