Coptopsyllidae

Definition

A family of fleas (order Siphonaptera) within the class Insecta, characterized by their parasitic lifestyle on mammalian hosts. Members of this family possess the typical laterally compressed body form, powerful hind legs adapted for jumping, and mouthparts specialized for piercing skin and sucking blood that define the order. Coptopsyllidae represents one of the approximately 15–20 recognized families of fleas, a group of particular significance in medical and veterinary entomology due to their roles as disease vectors and nuisance parasites.

Etymology

From the type genus Coptopsylla (Greek koptos 'cut, beaten' + psylla 'flea') + -idae (family suffix)

Example

Fleas in the family Coptopsyllidae, like other siphonapterans, undergo complete metamorphosis with worm-like larvae that feed on organic debris in host nesting material rather than blood, distinguishing their immature ecology from the obligate hematophagy of adults.

Usage Notes

Coptopsyllidae is one of the smaller and less-studied families of fleas compared to the medically prominent Pulicidae (which includes the cat flea Ctenocephalides felis and human flea Pulex irritans). The family's host associations and vector competence remain poorly documented relative to major flea families. When encountered in field collections, specimens require microscopic examination of chaetotaxy (bristle arrangement) and genitalic structures for definitive family-level identification.
