摘要
A new species of Hyolithes Eichwald from the Permian of Tepuel-Genoa Basin is described and figured. Hyolithes patagoniensis nov, sp. is endemic and differs from other known species in the apical angle, size and absence of dorso-lateral bands. The affinities and stratigraphic and geographic distributions are discussed. Its relationships with Hyolithes amosi Gonzalez y Sabattini and Hyolithes spp. from the Tepuel and Languineo Hills are analyzed., The records of new localities extend the geographic distribution of Hyolithes amosi.
