Lectotype of Centroptilum poeyi . Male imago, “ Cuba,” Poëy 1864.

Eaton (1885) described Centroptilum poeyi from Cuba based on males. He stated that it was from the “Rangel Mountains, Cuba (Poëy & Ch. Wright) [Hag. Mus.].” Gundlach (1886) does not give this locality for C. poeyi . Traver (1938) suggested that C. poeyi was a species of Baetis (as defined in 1938) and Edmunds (1974) examined the type material and confirmed this placement. McCafferty and Waltz (1990) then included the species in Fallceon , a genus established by Waltz and McCafferty (1987). Kluge (1992b) reexamined the type material and designated a lectotype; in the same paper he limited the paralectotypes to three specimens and redescribed the species based on the lectotype and fresh material of the male, female, and nymph from the Western, Central, and Eastern regions of Cuba. Later, McCafferty and Lugo-Ortiz (1994) concluded that the material treated by Kluge as Baetis (Fallceon) poeyi represented a new species which they named Fallceon nikitai . They explained that the syntypes of Baetis poeyi which they examined did not have a hook-shaped costal projection on the hind wing but that the material described by Kluge did have such a projection. According to Kluge and Novikova (2014) who synonymized the two species, the hook is present on both. Fallceon nikitai is a common species with broad, well-tracheated gills.

Ecology. Benítez (2007) found this species in both rapids and pools in the Yáquimo and Sevilla Rivers in Las Tunas Province where it appears to prefer faster waters. Cañizares (1998) stated that nymphs are active swimmers in backwater areas but are often found avoiding the fastest current between rocks on the bottom of rivers. The species is abundant in all altitudinal zones but collected most frequently between 250 and 750 m.

Geographic distribution. The species is found throughout the Cuban archipelago and has been collected in all four geographic regions ( Kluge 1992b, McCafferty and Lugo-Ortiz 1994, Cañizares 1998, Naranjo and Cañizares 1999) ( Fig. 5 ). The actual locality for the lectotype is unknown. It has also been found in the Dominican Republic and Jamaica ( Naranjo and Peters 2016).
