Holotype. Male imago, Province Santiago de Cuba, La Alcarraza (Guamá), 7-II-1989, N. Kluge.

The two species in the sacculobranchis species group are recognized by a transverse row of setae positioned on the basal third of forefemora. The species T. sierramaestrae is easily recognized by pale operculate gill covers with only a narrow dark line proximally.

Ecology. The nymphs are found crawling on or between rocks in areas of rapids with little current. They are most abundant in lower zones of streams, although some were found up to an altitude of 900 m. Nymphs were present in the months of February, March, April, June, October, and December which would indicate that adults may emerge at any time of the year.

Geographic distribution. The species is found only on the southern slopes of the Sierra Maestra and Gran Piedra mountain ranges ( Kluge and Naranjo 1990) in the Eastern Region ( Fig. 14 ).
