A new record of the Cuban endemic mayfly Poecilophlebia pacoi (Kluge, 1994) (Ephe­meroptera, Leptophlebiidae) from Gran Piedra massif, eastern Cuba

The endemic mayfly Poecilophlebia pacoi Kluge,1994 was described for Turquino massif, Sierra Maestra mountain range, Cuba. So far it was known only from two river catchments within this country. Distribution of Poecilophlebia pacoi extends up to Gran Piedra massif of Sierra Maestra mountain range. The main distinguishing morphological characteristics of the larvae were used for the species recognition. Also previous and new locality are georeferenced and mapped. The new record expands the known distribution range of P. pacoi approximately 55 km to the east and suggests the possibility of finding additional records farther from the type locality.
