- Abstract
Monotrabs goricanae n. sp. is a new species belonging to the Tritrabidae family (Spumellaria, Radiolaria). Monotrabs goricanae n. sp. has been discovered in the Middle Jurassic pelagic successions from northwestern Sicily (Favignana Island) and the Southern Alps (Cava Vianini and Coston delle Vette) (Italy). Monotrabs goricanae n. sp. is characterized by having one ray with a tritrabid structure, a bulbous distal part with two stout lateral opposite spines, and a proximal part always incomplete. The external longitudinal beams are nodose and separated by grooves with two rows of rounded pores. Remains of very small spines occur sometimes on the external edge of the bulbous portion and on the external longitudinal beams. Monotrabs goricanae n. sp. is a good stratigraphical marker for the Middle Jurassic time.
