Identification

Distinguished from other Bdellidae by the presence of prominent spine-like setae on the idiosoma and legs. The gnathosoma (mouthpart region) is typically elongated, as in other bdellids. Specific diagnostic characters require microscopic examination of setal arrangement and chaetotaxy patterns.

Habitat

Soil and leaf litter environments; associated with decomposing organic matter and moss layers.

Taxonomic note

The Spinibdellinae was established to accommodate bdellid with distinctive spinose setation. The type genus is Spinibdella. The group has been subject to taxonomic revision, with some genera transferred between subfamilies as character concepts have evolved.

Research status

With only 6 observations on iNaturalist and limited published studies, Spinibdellinae represents a data-deficient group within the Bdellidae. Most knowledge derives from taxonomic rather than ecological research.
