A redescription of a Maastrichtian lobster Hoploparia antarctica Wilckens, 1907 (Crustacea: Decapoda), from Chubut, Argentina

The discovery of beautifully preserved specimens of a macruran decapod provides the basis for redescription of Hoploparia antarctica Wilckens, a hitherto poorly known species from the Campanian-Maastrichtian of the Austral Basin of Southern Patagonia. Analyses of the associated molluscan fauna, trac...
