Canthyloscelididae

Definition

A small family of minute, fungus-feeding midges in the order Diptera, historically allied with the Scatopsidae (minute black scavenger flies) and currently placed in the infraorder Psychodomorpha. Adults are typically found in moist, shaded habitats such as forest floors and wetlands; larvae develop in decaying organic matter and fungal fruiting bodies.

Etymology

From Greek kanthylos (small basket or pack) and skelos (leg), with the family suffix -idae.

Example

Canthyloscelididae larvae are recovered from decomposing polypore fungi and saturated leaf litter in temperate rainforest surveys, where their presence indicates advanced decay stages and stable moisture regimes.

Synonyms

• Canthyloscelidae

Usage Notes

The spelling 'Canthyloscelididae' (with the medial -id-) reflects a subsequent emendation of the original 'Canthyloscelidae' and is now the prevailing form in modern taxonomic databases (GBIF, EOL). The family is morphologically cryptic and frequently overlooked in standard Malaise trap samples; specialized emergence traps or direct extraction from fungal substrates are required for reliable detection. Formerly treated as a subfamily of Scatopsidae or as a distinct family of uncertain placement; molecular phylogenetics has clarified its position within Psychodomorpha, separate from the scatopsid lineage.
