Tricorythodes explicatus
(Eaton, 1892)
Tricorythodes explicatus is a of small in the Leptohyphidae, first described by Eaton in 1892. It belongs to a commonly known as stout mayflies, characterized by reduced wing venation and robust body proportions. The species has been documented in Middle America and North America, though detailed biological studies remain limited.

Identification
Members of Tricorythodes can be distinguished from related by forewings with greatly reduced costal brace and crossveins, combined with hindwings that are small or absent. Specific identification of T. explicatus requires examination of genitalia and detailed wing venation patterns; reference to original description by Eaton (1892) and subsequent taxonomic revisions is necessary for definitive determination.

Habitat
Associated with freshwater lotic environments, specifically streams and rivers, based on -level and documented distribution in running water systems of the Nearctic and Middle American regions.
Distribution
Recorded from Middle America and North America (Nearctic region). Specific country-level records require verification from primary literature.
Life Cycle
As with all Ephemeroptera, development includes aquatic nymphal stages followed by winged subimago and stages. Detailed parameters for this are not documented.
Ecological Role
Nymphs function as or gatherers in stream , processing detritus and contributing to nutrient cycling; serve as prey for aquatic and terrestrial .
