Abstract

Bahadzia caymanensis, a new stygobitic species is described from a shallow, weakly brackish-water pool in a small cave on Grand Cayman Island in the Cayman Islands. Further exploration and collecting from the type-locality of Bahadzia yagerae in Cuba has provided more data, allowing for a thorough redescription of this species. With the description of Bahadzia caymanensis, there are now 11 species within the genus. Revised phylogenetic and biogeographic analyses of Bahadzia offer further support for a close phylogenetic relationship between Bahadzia and the predominately freshwater genera Mayaweckelia and Tuluweckelia on the Yucatan Peninsula.
