Description (male). Agreeing with generic description given above.

Coloration generally tawny-yellow. Head: parafacial white-pruinescent. Antenna largely dark brown. Thorax without darker markings. Fore tarsus faintly browned apically. Wing hyaline; halter yellow to tawny-yellow.

Postabdomen. Sclerites of sternite 6 little developed and pigmented; surstylus ( Fig. 15 View Figures 15, 16 ) with almost straight lateral outline and with distal outline oblique, straight to slightly curved; aedeagal rod with acute, usually deflexed lobe near mid-length, beyond lobe slender, almost straight, tapering to very narrow simple apex.

Dimensions. Total length, 4.1–4.9 mm; length of thorax, 2.2 mm; length of wing, 4.9–5.2 mm.

Distribution. New South Wales: Blue Mountains and north to ranges east of Glenn Innes; coast district just south of Sydney. Tasmania: north-east.

Notes. Paranomina stuckenbergi   resembles P. mouldsorum   and P. hendeli   . It is without any distinct brown markings on the thorax, and in the male the surstylus and aedeagal rod are of characteristic shape. Females cannot be determined with certainty, though some specimens associated with males are provisionally sorted to this species.

Probably all or most of the specimens were taken on Xanthorrhoea   plants, though few are so labelled.

The specific epithet refers to my late friend Brian R. Stuckenberg, formerly of the Natal Museum, Pietermaritzburg, who made a significant contribution to knowledge of Old World Lauxaniidae   .
