Risananeiza crassaparies n. sp. from the upper Chattian of Porto Badisco (southern Apulia, Italy).

ABSTRACT: A new species of Rotaliidae, Risananeiza crassaparies n. sp., is described from the upper Chattian of the Porto Badisco Calcarenites (Salento Peninsula, Southern Italy). The studied specimens are assigned to the foraminiferal genus Risananeiza based on the presence of vertical canals in both the ventral and dorsal side of the test, and an intraseptal canal system that evolves into marginal sutural canals. The new species differs from the type species of the genus, R. pustulosa, in having a lower chamber lumen, and smaller dimension.
