摘要

Two new paguroids, Cretatrizocheles olazagutiensis n. gen., n. sp. and Mesoparapylo-cheles inichaeljacksoni n. gen., n. sp., both based on carapaces, are described and added to the very diverse mid-Cretaceous (Albian-Cenomanian) decapod crustacean fauna of the reefal deposits near Alsasua (Navarra, northern Spain). The description of Annuntidiogenes worfi is emended on the basis of a newly discovered, much more complete carapace. Mesoparapylocheles n. gen. is a member of the Parapylochelidae n. fam., whereas Cretatrizocheles n. gen. is a member of the Trizochelinae. These species show that the linea transversalis, introduced by neontologists for a groove lateral and/ or posterior to the cervical groove, is an evolved part of the branch iocardiac groove.
