"Two species belonging to the family Leptophlebiidae occur in Martinique, both new records : Hagenulopsis traverae marginata n. ssp. new subspecies of H. traverae (Peters, 1971), described from Dominique island, and Terpides jessiae Peters & Harrison, 1974, described from St Vincent. Morphology of adults and last-instar larvae of H. traverae marginata was compared to H. traverae traverae and to H. guadeloupensis Hofmann & Peters, 1999, described from Guadeloupe. Only chromatic differences and a variation in the number of cross-veins in anterior wings were visible, according to a gradient Martinique-Dominique-Guadeloupe, an argument rather in favour of three subspecies of the same species. Larval morphology of H. traverae marginata was also compared to H. minuta Spieth, 1943 from French Guiana. Among other differential characters, this latter species bears chloride cells on labrum, an adaptation to the very low water conductivity in Guiana. The female imago of Terpides jessiae, so far unknown, is described. Morphology of larvae is compared to T. guyanensis Demoulin, 1966. In Martinique, H. traverae marginata is replaced downstream by T. jessiae, less alticolous and less rheophilic, but clearly more tolerant of anthropic disturbances. H. traverae marginata is among the most sensitive lotic bioindicators of Martinique ; but the survival of T. jessiae, living only in low elevation streams and rivers, is even more threatened, in particular due to catastrophic agricultural practices. In French Guiana, Hagenulopsis minuta and Terpides guyanensis (respectively vicariants of the two latter species) are seldom sympatric." .
