Cloeodes superior Kluge 1991:130 (male and female imagos, nymph).

Holotype. Male imago, Province Santiago de Cuba, La Alcarraza (Guamá), 4-II-1989, N. Kluge.

The species was described from specimens collected in La Alcarraza, Arroyo Paco and La Idalia (Guamá), Santiago de Cuba. Nymphs of Cloeodes have no denticles on the claws, the gills are simple and tapered with smooth margins, and rows of fine hyaline setae are found on the basal outer margins of tibiae and tarsi. The first abdominal sternum is smooth and the second to sixth sterna have transverse rows of small setae. Nymphs of C. superior can be distinguished from C. inferior by shorter gills and generally dark abdominal terga which usually lack the darker anteromedian markings on each tergum characteristic of C. inferior . In adult males of C. inferior , there is no keel between the basal segments of the forceps.

Ecology. Nymphs are encountered in submerged vegetation in cool, clear waters at a depth between 30 and 50 cm. Kluge (1991) named this species C. superior because he found it only at higher altitudes; it has now been collected over a wide range of altitudes but usually above 500 m ( Cañizares 1998, López et al. 2004).

Geographic distribution. The distribution of this species in Cuba ( Fig. 3 ) is restricted to the mountain ranges of Sierra Maestra and Nipe-Sagua-Baracoa in the Eastern Region and the Guamuhaya Mountains of the Central Region ( Cañizares 1998, López et al. 2006). It is also recorded from the Dominican Republic ( Naranjo and Peters 2016).
