Tricorythodes cubensis Kluge and Naranjo 1990:571 (male and female imagos, nymph).

Holotype. Male imago, Province Cienfuegos, Altura de Trinidad, 15-V-1989, N. Kluge.

In the cubensis species group, there is transverse row of strong setae near the middle of the forefemora and operculate gills are broadest in their basal half. Originally described from several regions in Cuba by Kluge and Naranjo (1990), the species T. cubensis has distinct posterior bands on the femora.

Ecology. Nymphal ecology is similar to that of T. sacculobranchis . The species is found over a broad range of altitudes and has been collected in every month except September and October, indicating that emergence may occur throughout the year.

Geographic distribution. Tricorythodes cubensis has been collected from all the major mountain regions of Cuba ( Kluge and Naranjo 1990), but it has not been found in the Central-East Region which is composed of plains at low altitudes ( Fig. 16 ).
