Notes.

The syntype series of L. sanctivincenti is divided between Grenada and St. Vincent ( Ashmead 1900), which are islands separate by approximately 100 km. However, there are 22 intermediary islands in the Grenadine Island chain, so the maximum distance between landmasses is an order of magnitude less. Despite the name, L. sanctivincenti does not seem common on St. Vincent. In fact, all the specimens examined above belong are from islands to the south. To date, L. sanctivincenti and Habralictus insularis Smith-Pardo 2009 are the only halictid bees known from Grenada. Cockerell (1937) records L. sanctivincenti from Barbados, 160 km east of St. Vincent, however, his description of the darker colour and 'mesothorax highly polished’ do not seem consistent with the syntype series of L. sanctivincenti .
