South African endemic
Provincial distribution
Eastern Cape, Western Cape
Cape Town to Port Elizabeth.
Habitat and Ecology
Major system
Major habitats
Albany Thicket, Fynbos
Damp brackish flats near the coast, around estuaries.
It is threatened by ongoing habitat loss and degradation due to urban and industrial expansion on the Cape Flats and at Port Elizabeth. If it occurs elsewhere along the coast, it is possibly less threatened, but coastal development is also an ongoing threat around many estuaries.

A rare and very poorly known species, recorded from three widely disjunct localities. It is possibly localized to estuaries, but the most recent record dates from 1957, and all records have imprecise locality descriptions. Historical localities on the Cape Flats are likely to be locally extinct due to habitat loss, but it possibly still survives at De Hoop and the Swartkops Estuary near Redhouse, Port Elizabeth. Other estuaries between Cape Town and Port Elizabeth needs to be surveyed for the presence of this species.
