Rivulus Poey. It comprises at least two valid species of nonannual fishes (max. 50 mm SL) distributed in freshwater systems of Cuba ( Ponce de León et al., 2014). The genus is distinguished from other non-annual rivulines by the following synapomorphies: all hypurals fused (single plate); neural prezygapophysis of caudal vertebrae rudimentary; fourth ceratobranchial teeth absent; about 50% of anterior half of caudal fin covered by scales; four neuromasts on the anterior supraorbital series; and black round spot with white margin on the dorsoposterior portion of caudal peduncle in females ( Costa, 2011a).
