( Fig. 4 A-B) Diagnosis: Within the Peromyia dissonadissona group, P. warraensiswarraensis and P. praeclarapraeclara (see JASCHHOF & JASCHHOF 2004: 118 f.) are the only species possessing bilobed gonostyli. Even so, the gonostylus structure in these two species is fundamentally different: while the subbasal lobe in P. warraensis emerges from the dorsal surface of gonostylus, it emerges from the ventral surface in P. praeclara . Further differences lie in the outline of gonocoxites and tegmen. For instance, the ventral emargination of gonocoxites is shallow in P. warraensiswarraensis and deep in P. praeclara , and the tegmen is short and rounded in P. warraensiswarraensis and long and pointed in P. praeclara . Description (mentioned are only those features which differ from that in P. grovei ): Male. Head: Maxillary palpus 4-segmented, first segment with hair-shaped translucent sensilla. Wing: AntC ending at juncture with R5. ApicR1 = 3.0-3.5 times the length of Rs. Terminalia: Sclerotization of tg9 not or only insignificantly interrupted mesally. Ventral emargination of gonocoxites wide and shallow, not reaching to midlength ( Fig. 4A ). Gonostylus bilobed, ventral lobe elongate, with dense brush of apical setae, dorsal lobe attached subbasally, sparsely setose ( Fig. 4A ). Tegmen small, weakly membranous, shorter than gonocoxites, slightly tapering towards apex, rounded apically; ventral plate barely traceable, its basal margin deeply incised, apical margin situated just below tegmen apex ( Fig. 4B ). Female and preimaginal stages. Unknown. Etymology: The name is derived from the type locality, Warra.
