Neoleptophlebia heteronea

Neoleptophlebia heteronea is a species of mayfly in the family Leptophlebiidae, first described by McDunnough in 1924. The genus Neoleptophlebia is characterized by reduced wing venation and specific gill structures in the nymphal stage. This species is part of a diverse group of small to medium-sized mayflies commonly known as prong-gilled mayflies, referring to the distinctive forked gills of their aquatic nymphs. Very few observations of this species have been documented, with only four records on iNaturalist, indicating it may be rare, geographically restricted, or undercollected.
