Classification and geographic distribution of Stylodictya-type radiolarians

A collection of radiolarian Stylodictya-type shells from 17 surface sediment samples from the equatorial to Antarctic W Pacific Ocean was studied. Comparison of conventional taxonomic criteria used for the identification of the closely related taxa Stylodictya multispina, S. aculeata, Porodiscus spp...

Description
Summary:A collection of radiolarian Stylodictya-type shells from 17 surface sediment samples from the equatorial to Antarctic W Pacific Ocean was studied. Comparison of conventional taxonomic criteria used for the identification of the closely related taxa Stylodictya multispina, S. aculeata, Porodiscus spp. and Stylochlamydium asteriscus with the results of an objective numerical analysis of 11 two-state and quantitative characters suggest that S. multispina and Porodiscus spp. are members of the same taxonomic unit which decreases in abundance from the equator to the Antarctic. -from Authors Fil:Boltovskoy, D.
