Macpherson (1957) noted that this species is "related to Coxiella exposita (Iredale) both in conformation and in the form of the operculum. It differs in its lighter coloration and in the absence of concentric lirae."
Genus Coxiella Smith, 1894
Type locality: Morawa, Western Australia.
We follow Macpherson (1957), which is the latest taxonomic treatment of this group.
Members of Coxiella are amphibious, inhabiting salt lakes and coastal salt marshes across the southern half of Australia. Empty shells often form pink tidelines around lake shores.
The animals are characterised by a deep furrow on each side of the head, and a suprapedal fold around the sides of the foot. Movement is by steps. The snout is long. The eyes have a cluster of glands above them. Coxiella are dioecious. Development is direct. Females are oviparous, depositing eggs singly in capsules coated in sand or mud. Coxiella probably feed on organic detritus. They are amphibious.
Southwest coast and Indian Ocean divisions, Western Australia.
