Teleochilus balcombensis is an extinct species of sea snail, a marine gastropod mollusc in the family Raphitomidae.[1] Fossils of the species date to the middle Miocene, and have been found in strata of the Port Phillip Basin of Victoria, Australia.
In the original description, Powell described the species as follows:
Shell of moderate size, slender, subcylindrical, but with the spire-whorls noticeably convex. Aperture about half height of shell. Post-nuclear sculpture of 8-9 flat-topped, moderately strong cords, with inter-spaces averaging half their width. Two to four cords on the median area of the body-whorl are bifurcated by a linear groove. There are 26 primary cords on the body-whorl. Shoulder sulcus distinct, situated below the first subsutural cord. Axial sculpture of weak, wide-spaced folds on first 2-3 whorls.[2]
The holotype of the species measures 18 mm (0.71 in) in height and 6 mm (0.24 in) in diameter.[2]
