Macropsyllidae

Definition

A family of fleas (order Siphonaptera) characterized by relatively large body size and distinctive genitalic morphology. Members are ectoparasites of mammals, with host associations and geographic distributions that remain incompletely documented compared to more intensively studied flea families such as Pulicidae and Ceratophyllidae.

Etymology

Greek makros (large) + psylla (flea) + -idae (family suffix), referring to the comparatively large size of these fleas.

Example

Macropsyllidae species parasitize rodents and other small mammals in specific regional faunas, with their larger body size distinguishing them from the more common small fleas of family Ceratophyllidae collected from the same hosts.

Usage Notes

Macropsyllidae is one of the smaller and less economically significant flea families, rarely encountered in medical or veterinary contexts compared to Pulicidae (cat and dog fleas) or Tungidae (chigoe fleas). Identification to family level requires microscopic examination of abdominal and genitalic characters. The family's phylogenetic position within Siphonaptera has been revised in recent molecular studies, and its constituent genera and species may be subject to future taxonomic reclassification.
