Very similar to P. rieki ; relevant attributes as follows:

Male. Head ( Figs 18, 19 ) Carina pale brown in ground colour, silver pollinose, confluent with epistome, scarcely protruding past antenna in lateral view. Facial ridge with tiny setulae on some 50-70% of length above vibrissa. Vibrissae set about level with epistome margin, about as long as arista, inclinate but at most slightly decussate. Frons relatively broad ( Table 3 ), with 2 (occasionally 3) strong proclinate fronto-orbitals and 1 (dorsal) exclinate or reclinate. Genae, parafacials, parafrontals, and postorbitals silvery pollinose. Gular region not as strongly swollen as in rieki . Thorax. Propleuron with profuse setulae. Setulae beneath posteriormargin of scutellum sparse, not extending medially past bases of second marginal bristles (as in rieki ).

Lower calypter pale, posterior angle rounded. Lappet hairs of posterior spiracle numerous in some specimens, but not detected in many others (including holotype). Legs. Fore tibia without p seta. Postero-dorsal strip of hind coxa with several setulae in about 50% of specimens. Abdomen. Tergites metallic green, usually with at least a trace of apical darkening; Tl+2 sometimes dark orpurplish in some lights, very occasionally with a trace of pale frosting laterally. Genitalia as in Fig. 14 ; surstyles slightly clubbed apically, a little shorter than cerci.

Female. Generally similar to male, but facial ridges setulose over only 20-30% of their length.

Distribution ( Fig. 26 , p. 108). North Queensland and the Kimberleys; presumably also occurring in intervening areas.
