Abstract
This article re-evaluates the taxonomy of the radiolarian genus Longtanella Sheng and Wang, based on materials obtained from the Guadalupian (Permian) Gufeng Formation in Anhui, China. This leads to the improved description of two previously introduced species (L. zhengpanshanensis and L. turgida) and the documentation of two additional morphotypes left in open nomenclature (L. sp. A and L. sp. B). Based on the new observations and measurements of Longtanella specimens and co-occurring species of Parafollicucullus Holdsworth and Jones, Longtanella differs from Parafollicucullus by having a turriform, slightly bent test and lacking a clear wing or pseudothorax.
期刊介绍：
La Revue de micropaléontologie publie 4 fois par an des articles de intérêt international, consacrés à tous les aspects de la micropaléontologie. Les textes, en anglais ou en français, sont des articles originaux, des résultats de recherche, des synthèses et mises au point, des comptes rendus de réunions scientifiques et des analyses de ouvrages. La revue se veut résolument ouverte à tous les aspects de la micropaléontologie en accueillant des travaux traitant de la systématique des microfossiles (et de leurs équivalents actuels), des bactéries aux microrestes de vertébrés, et de toutes leurs applications en sciences biologiques et géologiques.
