Abstract

A new genus and species of raninid crab, Bicornisranina bocki, is described from the Upper Cretaceous Haslam and Pender formations of Vancouver Island, British Columbia, Canada. Bicornisranina bocki (Raninidae: Raninoidinae) shares similar characteristics with other genera within Raninidae, including a bifid anterolateral spine, as seen in Rogueus, and a similar frontal spine conformation as seen in Raninoides. Although B. bocki shares morphological characteristics with other genera within Raninidae, B. bocki possesses a distinct sternum that sets it apart and warrants establishment of a new genus. With the occurrence of Bicornisranina from lower Campanian rocks of Vancouver Island, the range of Raninoidinae is confidently extended into the Cretaceous.
