Traverina oriente was described from the Río Naranjal in the Eastern Region (Kluge 1994). It is distinguished from T. cubensis by the relatively shorter, rounded lateral processes of the gills.

Ecology. Aldana and Fonseca (2001) collected nymphs in rapids but more commonly in pools with sandy bottoms; Hernández and Bauta (2003) found them more frequently in rapids. Our experience is that they are more common in rapids than backwaters, but the form of the abdominal gills aids them to survive in lentic waters. Although present in a broad altitudinal range (sea level to 900 m), they are most frequent below 250 m. Mature nymphs have been found throughout the year, indicating that emergence of adults is non-seasonal.

Geographic distribution. The species is uniquely found in the Eastern Region of the country (Kluge 1994; Naranjo and Cañizares 1999). Deposited in the collections are 127 specimens: 24 nymphs from the Río Mayarí , 9 from Río Cuzco in Guantánamo, 54 from the Río La Mula (Turquino), 2 from the Río Gibara , 30 from the Río San Juan , 4 from the Río Sevilla , 2 from the Río Guantánamo, and 2 from the Río Guamá. This demonstrates the broad distribution of the species across the Eastern Region of Cuba ( Fig. 12 ) .
