ZMB 34734, one possible syntype; ex Doering.

Remarks.

Dohrn did not mention on how many specimens his description was based, but the range of measurements indicate that he had several specimens at hand. Moreover, he mentioned "Ich erhielt dieselbe in einigen Exemplaren von meinem Freunde Dr. A. Stelzner mit einer grösseren Suite argentinischer, von ihm gesammelter Land- und Süsswasser-Conchylien. Da die andere unbeschriebenen Arten Manuscriptnamen von Herrn Dr. Doering in Cordova führen, so steht wohl deren Publikation in Bälde zu erwarten" ( Dohrn 1875: 203). These sentences make clear that Stelzner, Doering and Dohrn were in regular contact and transfers of material (with unpublished names) did occur. The type locality is likely Cerro de Chepes, Prov. La Rioja (teste Miquel 1993: 164), although there is also a Cerro Chepe in Prov. San Juan. Doering’s material has a very general locality that, however, falls within the distribution range of the species. It is therefore possible that Doering’s material was part of the original series and the specimen is thus considered a possible syntype. The current systematic position is after Miquel (1993).

Current systematic position.

Bulimulidae , Bostryx stelzneri (Dohrn, 1875).
