Two new records of aquatic Hemiptera (Belostomatidae, Mesoveliidae) from southern Florida, with keys to the genera Belostoma Latreille, 1807 and Mesovelia Mulsant and Rey, 1852 in Florida and the northern Caribbean

Abstract

Belostoma minor (Palisot de Beauvois, 1805) and Mesovelia polhemusi Spangler, 1990 are reported for the first time from the continental United States, in southern Florida. Ten species of Belostomatidae (water bugs) belonging to the genus Belostoma Latreille, 1807 are now reported from the United States, with three species documented in Florida; the record of a fourth species, B. flumineum Say, 1832, in Florida is doubtful. Four species of Mesoveliidae (water treaders) belonging to the genus Mesovelia Mulsant and Rey, 1852 are now documented from Florida and the United States. I provide keys to species of the genera Belostoma and Mesovelia in the northern Caribbean Bioregion, representing southern Florida, the Greater Antilles, and the Lucayan Archipelago.
