Type locality.

[Brazil] "Petropolis prope Rio Janeiro (Miers)".

Label.

"Petropolis Rio / F. Miers E[sq.]", taxon label in Pfeiffer’s handwriting. M.C. label style III.

Dimensions.

"Diam. maj. 12 1/2, alt. 11 mill.". Figured specimen H 14.3, D 12.5, W 4.7.

Type material.

NHMUK 1975488, lectotype (Cuming coll.).

Remarks.

Pfeiffer did not state on how many specimens his description was based, but described this taxon from "Mus. Cuming". This is contrasting the statement in da Silva and Thomé (2007), who said "Pfeiffer mentioned a single specimen"; they considered the specimen in NHMUK as the holotype ( da Silva and Thomé 2007: 14), but this does not follow Art. 73.1 and Recommendation 73F ICZN Code. The current systematic position follows Simone (2006).

Current systematic position.
