Hectopsylla is a genus of fleas in the family Hectopsyllidae that parasitize non-volant mammals, birds, and bats.

In the thorax, the metasternite and pro-processes are narrower, with the meta-thoracic epimerum having three bristles, but rarely four or two.

A series of twelve female specimen of H. broscus were found on Humboldt's hog-nosed skunk Conepatus humboldtii in Central Pampa, Argentina, in or prior to 1906.

[3] The species can be recognized by the fifth tarsal segment over both sexes, the sexual organs of the male, and the metathoracical epimerum of the female, which is curved.

It is differentiated from those species by its metepimeron, the shorter process of its lateral metanotal area, and the number of bristles on its abdominal terga.

[5] Its description was based on a sole female specimen taken from an unknown species of swift in Michoacán, Mexico.

The presence of the species in nasal cavities effectuated breathing difficulties in the parrot.

[9] The flea has been observed from northern Chile on Markham's storm petrel Hydrobates markhami to Marin County, California on the American cliff swallow Petrochelidon pyrrhonota; based on their age, the American cliff swallows on which the fleas were found had migrated at least once from their winter range in Uruguay, central Argentina, Paraguay, and Brazil, which lead the authors to state their presence might have been a natural introduction of the flea to California.

In the thorax, its epimerum is round above, and narrows ventrally; in the abdomen, segments two to seven of the sternites lack bristles.

"[3] In the United States, H. pulex has been found on the lesser long-nosed bat Leptonycteris yerbabuenae in Cochise County, Arizona.
