Holotype ♂. Victoria: Hall’s Gap, Grampians Ranges [c. 37°08'S 142°32'E], 10.i.1976, M.S.M., B. J.M. ( AM K.456345). Double mounted on micropin through polyporus; genitalia intact, partly exposed GoogleMaps   . Paratypes. Victoria: 6♂♂, same data as holotype ( AM, MV) GoogleMaps   ; 1♂, Mount William, near summit, Grampians , Dec. 1977, D.K.M., M.A. S. ( AM)   ; 1♂, Princess Margaret Rose Caves , 8 km NNW of Nelson, Nov. 1992, M.S.M., S.F.M., D.K.M. ( AM; McEvey 10750)   . Tasmania: 2♂♂, near Barnes Bay, Bruny Island , Dec. 1987, D.K.M. ( AM)   .

Other material examined. Victoria: some females from Hall’s Gap and Mount William ( AM) are probably conspecific with the males with which they were collected.

Description (male). Agreeing with generic description.

Coloration generally tawny-yellow. Head: face and parafacial yellow to creamy. Antenna largely dark brown to blackish. Humeral callus yellow, with isolated dark brown spot on lower margin. Fore tarsus usually tawny, sometimes brown distally. Wing hyaline; halter tawnyyellow, sometimes with darker capitellum.

Postabdomen. Sternite 5 undivided; sclerite of sternite 6 little pigmented; surstylus ( Fig. 20 View Figures 20, 21 ) somewhat elongate, slightly tapered distally, with rounded apex, with scattered setulae and compact sublateral apical tuft of setulae; each lateral rod of aedeagus ( Fig. 21 View Figures 20, 21 ) long and almost straight, with pair of apical teeth, one acute and laterally directed and one shorter, narrow, and medially inclined.

Dimensions. Total length, 4.2–4.8 mm; length of thorax, 1.9–2.1 mm; length of wing, 4.7–5.1 mm.

Distribution. Victoria: districts W of 143°E. Tasmania: Bruny Island.

Notes. Both sexes of Paranomina mouldsorum   can generally be distinguished from those of other species with tawnyyellow thorax and legs by the presence of a well defined dark brown spot on the lower part of the humeral callus ( Fig. 19 View Figure 19 ). Some specimens of P. hendeli   have a slight brown or greyish brown suffusion in this position, but this tends to merge with the greyish pruinescence of the mesopleuron, and that species is apparently geographically separated. The apex of the aedeagal rod in the male, with pair of divergent tooth-like lobes, is also distinctive, but somewhat resembles that of P. dayi   .

Probably all or most specimens were collected on foliage of Xanthorrhoea   , though they are not all so labelled.

The specific epithet refers to Barbara and Maxwell Moulds, who collected most of the specimens.
