The Tumbling Creek cavesnail (Antrobia culveri) is a species of freshwater cave snail with gills and an operculum, an aquatic gastropod mollusk in the family Amnicolidae.
Antrobia culveri is the only species in the genus Antrobia. This is an endangered species.
The common name refers to Tumbling Creek Cave, a National Natural Landmark, in Taney County, Missouri, USA.[1]
The Tumbling Creek cavesnail was described as a new species by Leslie Hubricht in 1971, from specimens taken by David Culver, Thomas Aley, and Hubricht in 1969 and 1970.Antrobia culveri is the type species for the genus Antrobia, also described as new to science in 1971 by Hubricht.
Hershler and Hubricht (1988) examined specimens of Antrobia culveri and confirmed the taxonomic placement of this species at that time in the subfamily Littoridininae. They also noted the similarity of the genus Antrobia to, but distinguished it from, the genus Fontigens, which contains cave-adapted snails found in other caves and springs of the Ozark Plateau in Missouri and Arkansas.
The Tumbling Creek cavesnail is a small, white, blind, aquatic snail.
The shell is small, conical, well-rounded and pale-yellow with about 3.5 whorls. The dimensions of the type specimen are as follows: height 2.3 millimeters (mm) (0.09 inches); diameter 2.0 mm (0.08 in); aperture height 1.2 mm (0.05 in); aperture diameter 1.1 mm (0.04 in).
