Descriptions and illustrations

Mueller (1859, p. 221); Bentham (1863, p. 215); Bailey (1899, p. 128); Hochreutiner (1900, p. 72); Wilson (1974, p. 174, fig. 17, 18); Cowie et al. (2013, p. 19, fig. 5, pl. 12); McLay (2022).

Typification

Mueller’s collection locality details on specimens relative to published protologues are notoriously vague. We here select a single specimen at K (ex MEL) as the lectotype as this can be unambiguously associated with a locality cited in the protologue ( Mueller 1859, p. 221). We assign only the left-hand piece to K 000659823, assuming that the remaining three pieces belong to K 000659825.

Distribution

Northern parts of the Northern Territory and Queensland, Australia .
