Type locality.

Label.

"Chanchamayo. / Peru", in da Costa’s handwriting.

Dimensions.

"Long. 34, diam. 11 mm."; figured specimen herein H 36.6, D 12.7, W 6.7.

Type material.

NHMUK 1907.11.21.20, lectotype; 1907.11.21.21, one paralectotype (da Costa coll.).

Remarks.

da Costa did not state on how many specimens his description was based, but mentioned "there appears to be much variation both in form and colour among the specimens collected of this species"; on the same page he did also describe a "var. albida " (his figs 2-2a) and a "var. ventricosa " (his figs 3-3a). The reference of Breure (1979) to "HT 1907.11.21.20" has to be interpreted as a lectotype designation under Art. 74.6 ICZN. This specimen corresponds to da Costa’s fig. 1a; the paralectotype matches closely the measurements given by da Costa (H 34.3, D 14.18, W 7.0). Köhler (2007) reported a specimen originating from Preston in the ZMB, which he considered as syntype.

Current systematic position.
