Two New Species of Fleas from Utah, with Notes on the Genus Ornithophaga Mikulin (Siphonaptera)

Abstract

The two new species of fleas described in this paper are of unusual interest. The first belongs to the well-known genus Catallagia Rothschild (Hystrichopsyllidae: Neopsyllinae), but is notable for the extreme modification of the male genitalia, a condition not reflected in the female; the second, a bird flea, belongs to Ornithophaga Mikulin (Leptopsyllidae: Amphipsyllinae), a remarkable genus recently described from the U.S.S.R. on the basis of one female specimen.
