Holotype ♂. New South Wales : Gibraltar Range National Park, swamp area, 9.ii.1982, B.J.D. ( AM K.456346). On leaves of Xanthorrhoea . On micropin through polyporus . Paratypes. New South Wales : 3♀♀, 10 km NW of “Tuglo”, 48 km N of Singleton, 9–10 Dec. 1981, B.J.D. ( AM). Queensland: 3♂♂, 2♀♀, Bunya Mountains, April 1972, G.D. ( AM, QM) .

Description (male, female). Agreeing with generic description, but with distinctive pigmentation of thorax and legs.

Coloration Head largely tawny to tawny-brown; face and parafacial more or less whitish-pruinescent, lower and some lateral parts of face grey-brown.Antenna tawny-brown with some grey pruinescence; segment 3 often partly darker; arista black. Prelabrum tawny-brown; palpus tawny to brown. Thorax largely tawny-brown; humeral callus blackish brown on c. lower quarter of surface; mesopleuron with dark brown zone covering anterior half and extending narrowly

surstyli, posterior view, scale = 0.2 mm. (24) Aedeagal complex, anterior view, scale = 0.2 mm.

to posteroventral extremity; sternopleuron largely brown, with greyish pruinescence. Coxae largely tawny; femora brown-black, narrowly tawny apically; tibiae dark brown to blackish; tarsi brown. Wing hyaline; halter dull yellow. Abdominal tergites tawny-brown to dark brown.

Male postabdomen very similar to that of P. mouldsorum except as indicated. Surstylus on distal surface commonly with one or two larger, prominent setulae; aedeagal rod resembling that of P. mouldsorum , but longer relative to surstylus, with medially placed terminal tooth compressed, broadly rounded in lateral view.

Dimensions. Total length, males 4.3–5.1 mm, female 4.6 mm; length of thorax, males 2.1–2.2 mm, female 2.1 mm; length of wing, males 5.3–5.5 mm, females 4.9–5.2 mm.

Distribution. Higher rainfall areas of south-eastern Queensland and north-eastern New South Wales.

Notes. Paranomina dayi is readily distinguished from other species by the extensive brown-black zones on the legs, thoracic pleura, and abdominal tergites. It is closest morphologically to P. mouldsorum , but the tooth-like projections on the aedeagal rod differ in shape.

The specific epithet refers to Barry James Day, who collected significant material for this project.
