Holotype. Mature nymph, Province Santiago de Cuba, Arroyo Paco ( Río Palma Mocha ), 4-II-1989, N. Kluge.

The type specimens of F. testudineus were collected in the localities of Palma Mocha, La Emajagua and Río Carpintero in the Sierra Maestra, during the months of December to February ( Kluge 1992b). According to Kluge (1992b), the species is recognized by the apically narrow paraglossae and the broad distal segment of the labial palpi.

Ecology. Fallceon testudineus has not been found in collections made by the group working on aquatic fauna at the Universidad de Oriente (Appendix 1). The species is very rare and possibly an endemic.

Geographic distribution. This species appears to be restricted to the Eastern Region of Cuba ( Kluge 1992b) ( Fig. 5 ).
