Status

"We group the six species, with 26-38 grooves on the last whorl, in the G. indentata complex (G. carolinensis [Cockerell], G. indentata [Say], G. ocoae Hubricht, G. praecox [H.B. Baker], G. rimula Hubricht, and G. umbilicata [Cockerell]). Three of these species (G. carolinensis, G. indentata, and G. praecox) have been reported from the vicinity of Washington, DC. In addition, any similar looking undescribed species mentioned by Hubricht (1985) would be in this complex" (Steury and Pearce, 2014).
