The type locality, Wermura Creek, emerges from a small cave then flows on about 200 m before disappearing in a subterranean outlet and reappears after 1 km in the mangrove from a large cave and flows to the Arguni Bay. It consists of a crystalline stream, narrow (to about 1 m wide), relatively shallow (up to about 1 m) and flowing in primary forest .
