TL;DR: Two new genera of Stomiiformes are described from the Oligocene of the Carpathians and of the Caucasus and are considered to be a species of unclear family affiliation.
Abstract: Two new genera of Stomiiformes are described from the Oligocene of the Carpathians and of the Caucasus. Jerzmanskaephos gen. n. (the type species is Polyipnus sobniovensis Jerzm.) from the lower bottom of the upper Oligocene of the Carpathians and of the Caucasus is most closely related to “maurolicid”-like genera of sternoptychids Valenciennellus and Danaphos. Xenomesopelagia gen. n. (the type species is Idrissia carpathica Jerzm.) from the upper Oligocene of the Carpathians is considered to be a species of unclear family affiliation, probably close to the aberrant line of Sternoptychidae comprising the Oligocene Caucasian genus Eknomodophos.
