Poduridae

Definition

A family of robust, short-bodied springtails (Collembola) constituting the monotypic superfamily Poduroidea within the order Poduromorpha. The family contains a single extant genus, Podura, with four described species including the widespread semiaquatic species Podura aquatica. Members are characterized by their stout, compact body form and reduced furcula relative to other springtail families.

Etymology

Example

Podura aquatica, the sole widespread extant species of Poduridae, is commonly found skating on the surface film of stagnant freshwater habitats, where its hydrophobic cuticle and modified body shape distinguish it from the more slender, elongate springtails of families such as Isotomidae.

Usage Notes

Poduridae is treated as a monotypic family; no other genera are currently assigned to it. The family is distinguished from other Poduromorpha by body shape and habitat association rather than by furcula morphology alone. Fossil species (P. fuscata, P. pulchra) from Baltic amber are assigned to the extant genus Podura, though their placement warrants caution given the family's modern ecological specialization.
