Tricorythodes montanus Kluge and Naranjo 1990:574 (male and female imagos, nymph).

Holotype. Female imago, Province Santiago de Cuba, Arroyo Paco ( Río Palma Mocha ), 21-II-1989, N. Kluge.

This species was described from Arroyo Paco in the Eastern Region by Kluge and Naranjo (1990). It is easily distinguished from the other member of the cubensis species group by markings of the femora which are not banded but which do have longitudinal grayish streaks.

Ecology. This species is found from almost sea level to 1750 m, although most frequently in the range between 250 and 750 m. Nymphs have been collected throughout the year which would indicate a nonseasonal life cycle. It may be locally abundant, and here we include a report of 150 specimens from the Río La Mula, Turquino Massif.

Geographic distribution. The species is reported from the Sierra Maestra and the Gran Piedra, Eastern Region, by Kluge and Naranjo (1990). In addition to the Río La Mula, Turquino Massif, we include other records for the northeastern subsector of Guantánamo Province (Massif Nipe-Sagua-Baracoa): 1 nymph de Río Toa and 1 from Río Mayarí ( Fig. 17 ).
