Etymology

Example

Rallidentidae nymphs are collected from stream substrates during benthic macroinvertebrate surveys used to assess water quality in lotic systems.

Usage Notes

A relatively obscure family within Ephemeroptera; specialists may encounter it in regional faunal surveys or phylogenetic studies of basal mayfly lineages. The family's circumscription and included genera require verification against current mayfly systematics literature, as GBIF placement alone does not confirm monophyly or comprehensive species inventory.
