It is a 3D body fossil. Its type locality is Harper's Hill, Hunter Valley (Mitchell coll), which is in a Sakmarian coastal sandstone in the Allandale Formation of Australia.

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

H.O. Fletcher 1958 (Planikeeneia minor)Moderately small, low-spired and depressed gastropods, five to six whorls of low convexity, narrowly phaneromphalous; sutures distinct, shallow; whorl profile sub-angulate, sharply angulate in steinkerns, upper surface broadly convex, slightly shouldered below the upper suture; a pseudo-selenizone developed on the periphery; lower surface of whorl flatly convex; columella lip thickened, reflexed, increasing in strength towards its junction with the slightly curved lower lip; character of outer lip not observed; aperture oval, obliquely transverse; ornamentation numerous fine, transverse lirae, 18-30 in 5 mm, directed obliquely backward to the periphery where they bend sharply back and forward again to form a narrow apparent band or pseudo selenizone; below the periphery the lirae extend to the umbilicns in a somewhat sigmoidal manner.
B. Runnegar 1969Large, relatively low-spired Keeneia having slightly to distinctly angular whorl periphery situated well below the mid-height of the whorl.
