A new species of Atractites, A. jeletzkyi n. sp., is described from the Lower Lias of Pfonsjoch (Tyrol, Austria). The species is based on a single well-preserved telum, stored at the Naturhistorisches Museum of Wien. It has fusiform outline and profile, slightly expanding adorally of its middle portion, almost circular cross section, and apical angle of ca. 12°. The surface of the telum is finely sculptured with longitudinal and transversal striae, probably due to diagenesis. The differences between A. jeletzkyi n. sp. and A. alpinus Guembel, 1861, A. indunensis (Stoppani, 1857), and A. elongatus (de la Beche, 1829) are discussed.

Abstract

A new species of Atractites, A. jeletzkyi n. sp., is described from the Lower Lias of Pfonsjoch (Tyrol, Austria). The species is based on a single well-preserved telum, stored at the Naturhistorisches Museum of Wien. It has fusiform outline and profile, slightly expanding adorally of its middle portion, almost circular cross section, and apical angle of ca. 12°. The surface of the telum is finely sculptured with longitudinal and transversal striae, probably due to diagenesis. The differences between A. jeletzkyi n. sp. and A. alpinus Guembel, 1861, A. indunensis (Stoppani, 1857), and A. elongatus (de la Beche, 1829) are discussed.
