We follow Macpherson (1957), which is the latest taxonomic treatment of this group.
Inhabits salt lakes and coastal salt marshes. 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.
From southeast South Australia to southern Victoria, and including northern and eastern Tasmania. The species has also been recognised from fossil deposits in New South Wales, and it may also occur in south-western New South Wales.
