Leptohyphes zalope Traver

Leptohyphes zalope is a common and wide­spread species, known from Arizona east to Texas and south to Costa Rica ( Baumgardner and McCafferty, 2000). Records given below from Grenada and Tobago extend the known range of this species into the Caribbean Islands, and make this only the second known species of leptohyphid known from both the Caribbean Islands and Continental America.

Leptohyphes zalope was collected from two different sites on the island of Grenada. The first (Grand Bras River) is a small river flowing mostly through a forest, and substrate composed primarily of large rocks and boulders, cobble and sand with abundant leaf debris. The second river (St. Mark’s River) flows through mostly forest in the upper part of its drainage, and agricultural land at lower elevations. For most of its length, substrate consists primarily of large rocks and sand with little leaf debris. In both cases, larvae were collected from submerged leaf debris. On the island of Tobago, L. zalope was collected in submerged leaf debris from a small stream flowing through forest, with substrate consisting primarily of rocks, cobble, and sand with much leaf debris present.
