(Williams, 1970)
Species Guides
2Caecidotea racovitzai is a small freshwater isopod in the Asellidae, originally described as Asellus racovitzai by Williams in 1970. This belongs to a primarily composed of subterranean and groundwater-dwelling crustaceans. Records indicate it has been documented in the United States, specifically in Vermont. Like other members of Caecidotea, it is likely associated with groundwater such as caves, springs, or environments, though specific ecological details remain poorly documented.

Habitat
Groundwater and subterranean freshwater environments. Members of the Caecidotea are predominantly stygobiontic (exclusively subterranean) or stygophilic (tolerant of subterranean ), occurring in caves, springs, wells, and hyporheic zones. Specific microhabitat data for C. racovitzai is not documented.
Distribution
United States: Vermont. Distribution records are sparse and based on limited collection data.
Similar Taxa
- Caecidotea forbesiOverlaps in northeastern North American distribution and subterranean preference; distinguished by subtle morphological differences in pleopod structure and body proportions, though precise diagnostic features for C. racovitzai require examination of .
- Caecidotea communisWidespread in eastern North American groundwater systems; differs in geographic distribution and specific cave system associations, with C. racovitzai currently known only from Vermont.
More Details
Taxonomic history
Originally described as Asellus racovitzai Williams, 1970, this was later transferred to the Caecidotea, which now encompasses most North American freshwater asellids previously placed in Asellus. The genus Caecidotea is characterized by reduced or absent and elongate body forms associated with subterranean life.
Conservation status
Not evaluated by IUCN. Limited distribution records and apparent restriction to groundwater suggest potential vulnerability to aquifer degradation and pollution, common threats to stygobiontic crustaceans.
