Types. Holotype ( F78454 ) and 2 figured paratypes ( F78455 ).

Type locality. 150 m west of 'Marohn' homestead, 4 km south-west of Gundy, NSW (Locality 28).

Stratigraphic position. In biociastic limestone, upper part of the Dangarfield Formation.

Geographic distribution. Type locality only.

Geological age. Late Tournaisian.

Etymology. This species was named after Professor I.A. Talent, Macquarie University as an acknowledgment for his supervision of this work.

Remarks. This species differs from Kimina globosa n.sp. in possessing spiral cords, and from Pseudoaclisina turgida (Yoo) in having more convex whorls. Palaeoalvania talenti n.sp. resembles some Recent rissoids, particularly Alvania , in shell shape and ornament, but differs in having a deviated protoconch.
