This species is most similar to E. (B.) acuminata in shell morphology, having weakly convex whorls, but differs in having fewer whorls and a shorter shell, and in being sculptured with weak, rounded axial ribs. This latter character is unique in the Queensland tateids, although narrow, rather sharp ribs are seen in E. (B.) corrugata corrugata. Anatomically, this species is closest to E. (B.) acuminata and E. (B.) zeidlerorum. E. (B.) pagoda lives together with E. (B.) rugosa but differs in lacking the axial ribs and in having an angulation in the middle of each whorl.

Original name: Edgbastonia (Barcaldinia) rugosa Ponder, Zhang, Hallan & Shea, 2019. In Ponder, W. F., Zhang, W. -H., Hallan, A., & Shea, M. E. (2019). New taxa of Tateidae (Caenogastropoda, Truncatelloidea) from springs associated with the Great Artesian Basin and Einasleigh Uplands, Queensland, with the description of two related taxa from eastern coastal drainages. Zootaxa 4583(1): 1-67.
Type locality: small spring on Myross Station, northeast of Aramac, Queensland.
The spring in which this species and the next were found is a small pool on flat ground and is not fenced or otherwise protected. While a detailed survey of this property has not been conducted, sampling so far has failed to find either this species or the next in other locations.
Known from one spring on Myross Station, near Aramac, Queensland (Barcaldine Supergroup).
