Tricorythodes sacculobranchis was originally described from Baconao by Kluge and Naranjo (1990) and is distinguished from T. sierramaestrae by heavy markings on the operculate gills covers.

Ecology. Nymphs are found on, under or between rocks in areas of rapids with slower current. They move quickly. This species is the most common member of the family and one of the most common Ephemeroptera in Cuba. It has a broad altitudinal distribution but is found most frequently below 500 m. Nymphs are collected in almost every month of the year indicating that adults should emerge throughout the year.

Geographic distribution. Tricorythodes sacculobranchis is widely distributed on the island ( Fig. 15 ) and is present in all four geographic regions including the Isla de la Juventud.
