Occurrence of the large ostracod, Chlamydotheca unispinosa (Baird, 1862), in temporary waters of Montserrat, Lesser Antilles

Abstract

Four populations of the large freshwater ostracod, Chlamydotheca unispinosa (Baird, 1862), were discovered on the Caribbean island of Montserrat. These are the first records of the species on Montserrat and extend its known distribution approximately 113 km northwest and 63 km southeast of the closest known populations on Îles des Saintes (Guadeloupe) and Nevis, respectively. We provide the first DNA barcode for C. unispinosa, a 686 bp fragment of the COI gene which may be used for future comparative studies of this widely distributed species.
