Caenis cubensis Malzacher, Naranjo, González-Lazo and Kluge 2007:226 (male and female imagos, nymph, egg).

Holotype. Male imago, Province Santiago de Cuba, Río Guamá (Sierra Maestra), 4-IV-1989, N. Kluge.

Originally described by Malzacher et al. (2007) from multiple localities in all regions of Cuba, this is the only species of Caenis on the island.

Ecology. Caenis cubensis is found in a wide range of altitudes up to 900 m, but it has been collected most frequently below 500 m and less frequently between 750 and 900 m, especially in Bayamesa National Park of the Sierra Maestra. Specimens have been collected in contaminated rivers, lakes and even a swimming pool ( Malzacher et al. 2007). Nymphs with black wing pads have been collected throughout the year.

Geographic distribution. Present in all four geographic regions of Cuba. Malzacher et al. (2007) stated that this mayfly is the most widespread of any species in the country and is possibly the most common species ( Fig. 19). Paratypes (Appendix 2) are listed from nine provinces and the Isla de la Juventud.
