Geographical distribution

( Fig. 59 ): West Indies: Cuba, Cayman Islands and Haiti, in Hispaniola.

Habitat and activity.

I collected this species along margins of the river Itabo, Isla de Pinos, Cuba ( Fig. 53 ); the adults were active during the day on wet, organic soil. Other specimens were collected about 8 meters from the river margins under leaf litter in shady gallery forest.
