Abstract
Adults and last juvenile stage of a new Dudanus species, Dudanus karra n. sp., are described and illustrated. Some data
on ecology and host plant are given. The new species was found in a restricted area on both sides of the border between
Italy and Slovenia and in Northwestern Italy (Aosta Valley). Figures of D. pallidus Dlabola, 1956 and D. javieri Remane
& Della Giustina, 1997, closely related to D. karra, are presented. D. karra differs from these taxa primarily by the shape
of the aedeagus. D. pallidus is recorded for the first time from Hungary and Greece. The possibly recent speciation of the
Dudanus species in the context of their morphological uniformity is discussed. The endangered condition of Dudanus
habitats is highlighted, in particular for D. karra.
