Additional information about the ants of the island can be found here: Ants of Hispaniola A work in progress. . . . . ..

falcaria, haytiana, insularis, schmitti, semiferox, striatula

lineolata, new species for island (Los Arroyos, 2014 collection)

Gnamptogenys Table
based on (Lattke 1995) Gnamptogenys falcaria (only known from Holotype queen), Gnamptogenys insularis ....new, Lattke 2002.....plus Gnamptogenys lineolata  and another new species for the island...need to fit all this into key
