A Ypresian Fossil-Lagerstätte was discovered in the late 1970s in a quarry at Solteri (Trento, northern Italy), but its peculiar fauna, dominated by deep-water bony fishes and subordinate crustaceans and vegetal remains, remained virtually unexplored for decades despite its potential interest.

Two new genera and species of the infraorder Caridea and one new genus and species of the section Homarida are established herein: Venzia ypresiana n. gen., n. sp., characterized by an elongate and upward directed rostrum with ventral spines; Solteria spinosa n. gen., n. sp., characterized by a short, straight, and spineless rostrum (both Pleocyemata, infraorder Caridea); and Trentastacus levis n. gen., n. sp., characterized by a smooth subcylindrical carapace without grooves or spines (Astacida, section Homarida). The newly established taxa are compared to extant and scarce representatives from the Eocene to further emphasize the uniqueness of this fossil association.

Abstract

A Ypresian Fossil-Lagerstätte was discovered in the late 1970s in a quarry at Solteri (Trento, northern Italy), but its peculiar fauna, dominated by deep-water bony fishes and subordinate crustaceans and vegetal remains, remained virtually unexplored for decades despite its potential interest. A descriptive analysis of the crustacean fauna revealed the presence of members belonging to the suborders Pleocyemata (infraorder Caridea) and Dendrobranchiata (superfamily Penaeoidea) and to the infraorders Astacida (section Homarida) and Brachyura. Two new genera and species of the infraorder Caridea and one new genus and species of the section Homarida are established herein: Venzia ypresiana n. gen., n. sp., characterized by an elongate and upward directed rostrum with ventral spines; Solteria spinosa n. gen., n. sp., characterized by a short, straight, and spineless rostrum (both Pleocyemata, infraorder Caridea); and Trentastacus levis n. gen., n. sp., characterized by a smooth subcylindrical carapace without grooves or spines (Astacida, section Homarida). The newly established taxa are compared to extant and scarce representatives from the Eocene to further emphasize the uniqueness of this fossil association.
