Apiotoma balcombensis is an extinct species of sea snail, a marine gastropod mollusc, in the family Cochlespiridae. Fossils of the species date to the middle Miocene strata of the Port Phillip Basin of Victoria, Australia, and likely represent a descendant species of the late Oligocene species Apiotoma janjukiensis, known from the same locality.
In the original description, Powell described the species as follows:
The holotype of the species has a height of , and a diameter of . It can be distinguished from other members of the genus due to its strong peripheral nodules (12-14 per whorl).
The species was first described by A. W. B. Powell in 1944, who believed that the species was likely a descendant of the late Oligocene A. janjukiensis, due to morphological similarities and as the fossils came from the same type localities. The holotype was collected prior to 1944 from Fossil Beach, Balcombe Bay, Victoria, Australia. It is held by the Auckland War Memorial Museum.
This extinct marine species occurs in middle Miocene strata of the Port Phillip Basin of Victoria, Australia, including the Gellibrand Formation.
