There are further specimens on slides without date and site of collection. Remarks. Vaillant (1956) listed 13 specimens examined in his description of this species, but did not designate a holotype (Fig. 6d). By an error in the text and figure captions, the species was mentioned as Wiedemannia rhynchops ssp. alpina in Vaillant (1965). The species is probably endemic to the Pyrenees or the Iberian Peninsula.
