The shell is pupiform, white and reaches about 1.8 mm in length. This species is most similar to E. (B.) colmani, which is darker and occurs 58 km away.

Genus Edgbastonia Ponder in Ponder, Wilke, Zhang, Golding, Fukuda, & Mason 2008 (Type species: Edgbastonia alanwillsi Ponder in Ponder et al., 2008).
Subgenus Barcaldina Ponder, Zhang, Hallan & Shea, 2019 (Type species Jardinella edgbastonensis Ponder & Clark, 1990)
Original name: Jardinella pallida Ponder & Clark, 1990. In Ponder, W. F. & Clark, G. A. (1990). A radiation of hydrobiid snails in threatened artesian springs in western Queensland. Records of the Australian Museum 42(3): 301-363.
Type locality: "Big Spring" about 3 km southeast of "Edgbaston" Homestead, about 30 km northeast of Aramac, Queensland.
Lives in springs in the Edgbaston group.
Springs on Edgbaston Station, about 30 km northeast of Aramac, and on the adjoining Myross Station, Queensland.
This is the smallest species in the Edgbaston Springs group. Specimens from the adjoining Myross Station are very similar and are tentatively referred to as E. (B) cf. pallida by Ponder et al. (2019).
