Teloganodidae

Definition

A family of small mayflies (Ephemeroptera) in the superfamily Ephemerelloidea, distributed across the Afrotropical and Oriental biogeographic realms. Teloganodidae are characterized by reduced wing venation and simplified genital armature compared to related ephemerelloid families, and their nymphs typically inhabit rocky or gravelly substrates in flowing water.

Etymology

From the type genus Teloganodes (Greek telos 'end' + ganos 'brightness' + -idae family suffix), referring to the apical markings on the wings of the type species.

Example

Nymphs of the Oriental genus Dudgeodes (Teloganodidae) cling to stones in fast-flowing Himalayan streams, using their flattened bodies and suctorial mouthparts to resist current.

Usage Notes

Distinguished from the related family Ephemerellidae by reduced costal brace in the forewing and fewer gills on the abdomen in nymphs. The family contains approximately 10 described genera and is poorly represented in temperate collections due to its tropical distribution.
