Cloeodes inferior Kluge 1991:133 (male and female imagos, nymph).

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

The species was described from specimens collected in Río Duaba (Baracoa, Guantánamo Prov.) and Río Baconao (Santiago de Cuba Prov.) in the Eastern Region and from Sierra de Trinidad, Sancti Spíritus, in the Central Region ( Kluge 1991). The abdominal terga are generally pale in color with a dark, contrasting median macula on the anterior margins, and the gills are more elongated than those of C. superior . In male imagos, there is a pronounced median keel between the basal segments of the forceps.

Ecology. Nymphs of C. inferior are found in submerged vegetation in areas of low flow in rivers with clean, well-oxygenated water ( Kluge 1991, Cañizares 1998). Previously the species was reported at lower elevations of the Sierra Maestra ( Naranjo 1986, Kluge 1991). More recently it has been collected at elevations up to 1750 m, although more frequently encountered below 500 m ( Cañizares 1998, Aldana and Fonseca 2001).

Geographic distribution. This species has been collected in all four geographic regions of the country ( Kluge 1991, Cañizares 1998, Aldana and Fonseca 2001) ( Fig. 3 ) and the Dominican Republic ( Naranjo and Peters 2016).
