I have seen one additional specimen, from the same general area as the type-locality: "W. bank of Turner R. above Kunagunarrina Pool, S. of Port Hedland, W.A., 25 June 1980, B. Duckworth. Map. Ref. = Marble Bar SF50-8- 344:155" (AM). It was reared by the collector from a snail, a species of "Quistrachia" (ms name).
For the 3 known specimens, the M-bend index (as defined above) is 2.3-4.0.
