Abstract

Liromissus, a new genus of chionine bivalve from the Neogene of Venezuela, serves as an example of the link between geographic range, endemism and extinction susceptibility. Unlike other Neogene tropical American chionine genera, Liromissus was not widespread in the tropical Western Atlantic and Eastern Pacific, but was instead restricted to the Atlantic Gatunian region. Late Neogene extinctions in tropical America affected taxa with restricted geographic ranges, and regions with higher degrees of endemism more severely. Accordingly, Liromissus is the only tropical chionine genus to suffer extinction during the Neogene.

The type species of Liromissus, L. quirosensis, was originally described as a member of the genus Lirophora. Morphological considerations preclude this assignment, but also demonstrate that Liromissus possesses all the characters diagnostic of the Chioninae.
