Dalmatian Barbelgudgeons

The Dalmatian barbelgudgeon (Aulopyge huegelii) is a European ray-finned fish species in the family Cyprinidae. It is the only member of the monotypic genus Aulopyge. The genus name is derived from the ancient Greek aulós (αὐλός, "flute") + pygé (πῦγή, "behind, rump"), and thus means approximately "fluted tail-stem". The specific name honours the Austrian naturalist and diplomat Charles von Hügel. Though the genus was established in 1841, the species was only mentioned but not described at that time; that happened the following year, and in 1843, the frequently-seen misspelling huegeli was introduced. Many fish databases use 1843 as the year of description. The IUCN Red List uses 1843 and also has an explanation of the confusion.

As its common name implies, it is a cyprinid looking somewhat intermediate between a barbel and a gudgeon. It is, however, only convergent to the typical gudgeon subfamily (Gobioninae) and in fact among the closest relatives of the typical barbels (Barbus and the doubtfully distinct Luciobarbus) – if it is not actually their closest relative.
