Two New Species of Leptohyphes (Ephemeroptera: Leptohyphidae) from Ecuador

Resumen

Leptohyphes liniti New Species and Leptohyphes nicholsae New Species are described from larvae taken in Ecuador. Leptohyphes liniti has a highly developed ridge on the hind femora and otherwise is most similar to Leptohyphes tacajalo Mayo, also from Ecuador. Leptohyphes nicholsae is closely related to L. curiosus Lugo-Ortiz and McCafferty, described from Costa Rica, but differs in the presence of abdominal tubercles and color pattern.
