Abstract
Otiorhynchus radjai sp. n. from Vis Island (Dalmatia, Croatia) is described. This new blind species, collected in a cave, is very closely related to some eyeless, hypogeous and/or cave dwelling Otiorhynchus from the Pre‐Alps of Lombardy and western Veneto (northern Italy) thus far included in the subgenus Troglorhynchus Schmidt, 1854. These species, however, share with the new taxon the untoothed femora, the united arms of female sternum 8, the spermatheca with nodus lengthened and body apex short, the ovopositor coxites with lengthened styles, being clearly separated at subgeneric level from the O. (Troglorhynchus) species living in the eastern Alps and Istria. The new subgenus Otiorhynchus (Baldorhynchus) subgen. n. (type species: Troglorhynchus baldensis Czwalina, 1875) is accordingly described.
