Label.

Dimensions.

"Longit. 27 millim.; long. 11 millim.", corrected to "Longit. 25 millim.; lat. 11 millim." in d’Orbigny 1838 [1834-1847]: 286; figured specimen herein H 24.3, D 12.8, W 6.8.

Type material.

NHMUK 1854.12.4.196, eight paralectotypes ( d’Orbigny coll.).

Remarks.

The type locality refers to the environs of Sicasica, prov. Aroma, Dept. La Paz. In d’Orbigny 1838 [1834-1847] two varieties were mentioned: var. A. "dans la province de Sicasica, près du bourg de Cavari" ( Breure 1973: 129, fig. 7), and var. B. "sur les coteaux du Rio de Meguilla, entre la ville de Lauza [sic, Laura] et Carcuato [sic, Circuata], province de Yungas" ( Breure 1973: 129, fig. 7). Breure (1975b) found in the MNHN collection only material from Cavari, thus var. A; the shell of this variety appeared to belong to Naesiotus . In the NHMUK collection, the specimens from the same locality (1854.12.4.195) prove to be a Bulimulus species; this lot is now excluded from the type series. The protoconch of the specimens in the second lot (1854.12.4.196) show that these can be unambiguously classified in Naesiotus .

Current systematic position.

Naesiotus pazianus ( d’Orbigny, 1835).
