Interchangeable taxa

This is a small but elegant species, which differs from the majority of its congeners in the absence of the fine, frosty granulation of the surface which is so characteristic of many of them, and in the somewhat obscure development of the axial ribs.


Type location: Mayaguez, Porto Rico.
