Günther Erich Freytag described the species in 1955 as Triturus vulgaris kosswigii, a subspecies of the smooth newt (now Lissotriton vulgaris).[2] After genetic data had suggested the smooth newt was a complex of distinct lineages,[6] Dubois and Raffaëlli, in 2009, recognised several subspecies, including Kosswig's smooth newt, as distinct species.[7] This was followed by subsequent authors.[3][4][8] Molecular phylogenetics suggested that the closest relative of Kosswig's smooth newt is the Greek smooth newt (Lissotriton graecus) from the Balkans.[8]

The species differs from other species in the smooth newt species complex mainly in the male secondary characters during breeding season.[4] The male dorsal crest is less than 1 mm high, but high at the tail base, has smooth edges, and ends in a long filament. The well-developed dorso-lateral folds give the body a square shape. The toe flaps are well developed.[5]: 234 

Paedomorphic adults have been reported for Kosswig's smooth newt.[9]

The species's

IUCN. Since its range is much smaller than that of the smooth newt species complex as a whole, it is likely to be more vulnerable than previously estimated.[1][4]
