Resumen:
A new species of Leptohyphes Eaton (Ephemerotera: Leptohyphidae) is described, diagnosed and illustrated from nymphscollected in the Pantepui region in Southeastern Venezuela. Leptohyphes kukenan sp. nov. is similar to Leptohyphespopulus Allen because they share a unique character for the genus: male compound eyes are divided. Other uniquecharacters for the new species include a plesiomorphic gill structure, with imbricated ventral lamellae, and paired subapicaldenticles on tarsal claw. The new species show a unique combination of characters that distinguish it from L. populus andall other species of Leptohyphes: fore and hind margin of femora with spines on strong elevated sockets, part of body andlegs covered by small pale spots, tarsal claws with 4?5 marginal denticles and a subapical pair of submarginal denticles,pronotum with large rounded lateral projection, hind wing pads absent in female, gill formula 8/7/7/4/1, operculate gillwith imbricated ventral lobes, and gill V without ventral extension on dorsal lamella.
