ABSTRACT. The article represents a review and partial revision of the genus Pontonyx Palatov et Marin, 2021 (Amphipoda: Crangonyctidae). A new species of the genus, Pontonyx abchasicus sp.n., is described from the mountainous forests springs of eastern Abkhazia, Caucasus, representing the highest mountain habitat (about 760 m a.s.l.), while previous records did not exceed 60 m a.s.l. Synurella donensis Martynov, 1919 is re-described in details on the basis of topotypic material and transferred to the genus Pontonyx. Discussion on phylogeny and distribution of the genus, as well as a differential key for all species are provided. The article also presents a general list of currently described Palearctic species of the family Crangonyctidae.
