Holotype. Male imago, [Province Mayabeque], Río Güines , March 1966, P. Alayo.

Farrodes bimaculatus was originally described from an adult from Mayabeque Province (Peters and Alayo in Peters 1971). The nymph was described by Kluge (1994) from localities in the provinces of Pinar del Río, Sancti Spíritus, Guantánamo, and Santiago de Cuba. It is most easily recognized by the large subapical denticle on the claws.

Ecology. According to the literature, nymphs of this species prefer rocky-bottomed or muddy-rocky rivers and actively seek refuge under stones. The species is abundant at all altitudes but mostly between 100 and 750 m and especially above 500 m. In the collections are 353 specimens collected from diverse habitats from backwaters to rapids, with a preference for rapids. Nymphs have been collected throughout the year, indicating a non-seasonal life cycle.

Geographic distribution. Based on data of Peters (1971), Kluge (1994), and the review of the collections used for this work, the species is widespread throughout the Cuban Archipelago and has been collected from all four regions of Cuba ( Fig. 7 ).
