Allenhyphes flinti (Allen)

Allenhyphes flinti was described in Leptohyphes by Allen (1973), based upon larvae from the island of Dominica in the West Indies. Hofmann et al. (1999) later reared this species, associated the adult, and listed new distributions records of the species from the island of Guadeloupe.

Molineri and Flowers (2001) recently discovered this species in Panama and Venezuela. Their report was the first known instance of a leptohyphid mayfly from both Continental America and the Caribbean Islands. Records given below extend the known range of this species in the Caribbean region to include the islands of Montserrat and St. Kitts.

On the island of Montserrat, A. flinti was collected from a very small stream on a steep slope at about 100 m elevation. Stream channel substrates included rocks and sand with some leaf debris. In Dominica A. flinti was collected from very small to medium­sized forested streams between 130 and 330 m elevation. Substrate in these streams included boulders, rocks, cobble, and sand with rooted aquatic vegetation along the shorelines and some leaf debris.

On the island of St. Kitts A. flinti was collected from a small permanently flowing stream in undisturbed forest with a bed composed mostly of rocks and sand, with some leaf debris. Regardless of site, larvae of A. flinti were collected from submerged leaf debris.
