Figs 17, 18

Holotype ♂. New South Wales: Goonoo State Forest , 17 miles [c. 27 km] NE of Dubbo, 25.iii.1971, D.K.M. ( AM K.456344). On leaves of Xanthorrhoea . On micropin through polyporus, right antenna damaged, postabdomen in microvial on main pin . Paratypes. New South Wales: 1♂, near Native Dog Hill , 38 km E of Rylstone, Nov. 1978, G.D. ( AM) ; 1♂, Mount Kaputar National Park, Narrabri district , c. 900 m, Jan. 1978, G.D. ( AM) .

Other material examined. New South Wales: 2♀♀, from Goonoo State Forest and Native Dog Hill respectively ( AM) are doubtfully referred to this species . 1♂, with same collection data as holotype, has slightly differently shaped aedeagal rods, and is considered doubtfully conspecific, in view of the paucity of study material .

Description (male). Agreeing with generic description in most characters.

Coloration generally tawny-yellow. Head: face and parafacial partly whitish-pruinescent. Antenna tawny-brown to darker brown. Palpus tawny, usually not much darker apically. Thorax without darker markings. Legs uniformly pale; tarsi not darkened distally. Wing hyaline; halter pale tawny, usually without darker markings. Abdomen tawny, sometimes partly discoloured in preserved specimens.

Postabdomen. General features as in P. stuckenbergi ; surstylus ( Fig. 17 ) straight, without lobes or tubercles, slightly expanded distally, but less so than in P. danielsi , with apical margin transverse but not straight, with slightly larger setulae; lateral sclerites of hypandrium oblique; aedeagal rod broad basally ( Fig. 17 ), distally anteriorly curved, broadly compressed in almost vertical longitudinal plane, with small sclerotized ridge on medial surface ( Fig. 18 ).

Dimensions. Total length, 4.5 mm; length of thorax, 2.1–2.3 mm; length of wing, 5.1–5.3 mm.

Distribution. New South Wales: mainly Western Slopes district, nearest coast record at Native Dog Hill, apparently c. 32°50'S 150°15'E. As the species has been rarely collected, its limits of distribution are probably incompletely known.

Notes. Paranomina martini apparently has the shape of the surstylus distinct from such related species as P. danielsi , P. stuckenbergi and P. mouldsorum . The distal part of the aedeagal rod ( Fig. 18 ) is distinct from all other known species but may prove to be slightly variable when the species is better known.

The specific name refers to John C. Martin, in recognition of help with photographic studies of Paranomina .
