Type material.

NHMUK 1889.11.19.1, lectotype ( Breure 1978: 16).

Diagnosis.

Remarks.

This species shows the same colour pattern and general shell shape as Plekocheilus (Eurytus) floccosus (Spix in Wagner, 1827), and is evidently closely allied to this species. Further studies should clarify the relationships between these species.
