As with most leptophlebiid mayflies, have two or three long caudal filaments and triangular forewings with numerous crossveins. Detailed identification requires examination of microscopic features; species-level identification is not possible from photographs alone.
Habitat
in this are associated with freshwater lotic environments, specifically streams and rivers. The nymphal stages inhabit the benthic zone of these water bodies.
Distribution
Documented distribution records include the departments of Santander and Tolima in Colombia. The likely has a broader Neotropical distribution given the Leptophlebiidae's in this region.

Ecological Role
Nymphs function as benthic or collectors in stream , processing organic matter and serving as prey for aquatic . provides a concentrated food resource for riparian .
