Tethysimyia species D , female, specimen from French Guiana. A. habitus, lateral view. B. head, anterodorsal view. FRENCH GUIANA : 2♀♀ , Macouria , 04°54ʹ50ʹʹN 52°21ʹ24ʹʹW, beach, marsh & mangrove, 2m asl , sweeping low vegetation, 12.ix.2015 , leg. M.J. Ebejer ( MJE ) . No important differences could be found between these two females from French Guiana and those of T. nigrifacies . Without associated males it remains possible that they represent a different species, particularly since several very closely related species to each other have been found on the island of Bonaire . French Guiana , located further east, has a climate and suite of habitats quite different from Bonaire .
