Other specimens examined. WESTERN AUSTRALIA: 1 0, 2¥ ¥, as for holotype; 14°35'S 125°45'E, Lone Dingo, Mitchell Plateau , Western Australia, 9-19 May 1983, LD. Naumann & J. Cardale, 10 .

Generally resembling P. rieki , with significant attributes as follows:

Male. Head ( Figs 20, 21 ). Carina short, narrow, not confluent with epistome, not protruding past antennal segment 3 in lateral view, dark brown with light silvery pollinosity. Facial ridge with setulae only close to vibrissa. Frons relatively broad as compared with head width, but rather short ( Table 3 ), with 2 strong proclinate frontoorbitals and 1 reclinate. Antennal segment 3 short, only as long as that of female. Vibrissae set a little above level of epistome margin, conspicuously long and strong, incurved, decussate. Genae, parafacials, parafrontals, and postorbits with silver pollen; gena conspicuously short, truncate ( Table 3 ). Thorax. Propleuron with several setulae. Scutellar setulae as for P. tropicalis . Lower calypter with exposed portion dark. Lappet hairs of posterior spiracle 1-2 in number, inconspicuous. Legs. Fore tibia without p seta. Mid tibia with 2-3 strong a setae. Postero-dorsal strip of hind coxa setulose. Wing. Setulae on basal node of R 3+4 extending half or more the distance to r-m (in other species, largely confined to the swollen base of the vein). Abdomen. T 1+2 dark purplish; T 3 metallic blue with median dark vitta and apical dark band, and conspicuous, pale silvery lateral patches (in posterior view) extending almost to midline; T 4 similarto T 3, but pale patches less conspicuous or absent; T 5 metallic purplish. S3 with only 4-6 long hairs, S4 without any. Genitalia practically identical with those of P. tropicalis .

Female. Generally similar to male.

Distribution ( Fig. 26 , p. 108). Known only from the Kimberleys, Western Australia.
