Holotype. Male imago, Province Guantánamo, Río Duaba (Baracoa), 15-III-1989, N. Kluge.

The type material of Americabaetis naranjoi was collected in the provinces of Guantánamo and Granma by Kluge (1992a). Nymphs are easily recognized by the banded caudal filaments and absence of gills on abdominal segment 1.

Ecology. According to Benítez (2007), nymphs of A. naranjoi are found swimming in stony-muddy rivers in areas with little current. They were collected at depths between 11 and 107 cm, and all were found at altitudes below 250 m. Results of Benítez (2007) correspond to results of Kluge (1992a) who suggested that species was an inhabitant of the potamal zone of rivers. Cañizares (1998) considers this a rare species in Cuban rivers.

Geographic distribution. The species is found in the Central Region (one nymph from Río Táyaba, Trinidad), Central-East Region (30 nymphs from Río Máximo) and Eastern Region of Cuba ( Kluge 1992a, Naranjo and González-Lazo 2005b) ( Fig. 2 ).
