Peromyia warraensis sp. n.

(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.

Types:

Holotype: Male, Australia, Tasmania, Warra LTER site, Mt Weld, 27 Feb. 2001, Malaise sample FT26, N. DORAN & R. BASHFORD (in AMS) . Paratypes: 1 male, same data as the holotype; 1 male, same data but sample FT19; 1 male, Warra LTER site, Manuka Road, 17 March 2004, Malaise sample FT30518, R Bashford; 2 males, same locality but 1 March 2005, samples FT35682 and 35685, respectively (in AMS and SDEI) .
