REDISCOVERY AND REDESCRIPTION OF AN ALMOSTUNKNOWN HEMICYCLA SPECIES (GASTROPODA,PULMONATA, HELICIDAE): H. EURYTHYRA 0. BOETTGER 1908FROM TENERIFE, CANARY ISLANDS

摘要

Hemicycla eurythyra 0. Boettger 1908, endemic to Tenerife, was rediscovered near its type locality. It is rede-scribed and compared with two conchologically similar taxa: H. pouchet (A. Ferussac 1821) and H. pouchadan Ibanez &Alonso 2007. H. eurythyra is grouped in the subgenus Hemicycla s. str. by the presence of a diverticulum in the bursa copulatrix complex.
