The trochiform shell is sculptured with fine growth lines. It reaches about 3.2 mm in length. It occurs with E. (B.) corrugata, and differs from that species in the lack of sculpture, in having a narrower umbilicus and a taller spire.

Original name: Jardinella edgbastonensis 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: Unnamed spring 2.3kms northeast of "Edgbaston" homestead, about 34 km northeast of Aramac, Queensland.
Lives in springs on Edgbaston Station and in a few springs on the adjoining Myross Station.
Springs on Edgbaston Station and a few on Myross Station, northeast of Aramac, Queensland (Barcaldine Supergroup).
Among the mound spring Edgbastonia (Barcaldinia) species, E. (B.) edgbastonensis is anatomically and conchologically the most similar to the tropical coast species of Jardinella.
