verging posteriorly and reaching beyond middle of tergite. First tergite with longitudinal rugo-striation, further tergites polished. Ground colour of body rusty brown, tergites dark brown. Scape and pedicel yellowish brown, flagellum greyish-brownish. Frons medially and occiput brown to dark brown, ocellar field black. Mesopleuron, metapleuron entirely and propodeum anteriorly dark brown to brown. Second tergite antero-laterally rusty brown, otherwise brown. Legs straw yellow, fifth tarsomeres faintly brownish. Wings hyaline, pterostigma opaque brown, veins light opaque brown. Female and host unknown. Distribution - Australia (New South Wales). The new species, Taphaeus robiginosus sp. n., is nearest, on the basis of our present taxonomic knowledge, to T. hiator (Thunberg, 1822). The two species are distinguished by the following features: 1 (2) Temple in dorsal view receded (Fig. 7). Pterostigma issuing radial vein distally from its middle (Fig. 10). First tergite clearly broadening posteriorly and a bit longer medially than broad behind (Fig. 9). First brachial cell less long, 3.2-3.3 times as long as high distally (Fig. 11, see arrows). Hind femur four times as long as broad medially, hind tibia somewhat thickening distally, i.e. 8.0-8.3 times as long as broad apically (Fig. 8). Body black to brownish black with less yellowish brown to rusty brown pattern. Male: 3.2-3.5 mm. Palaearctic Region T hiator (Thunberg) 2(1) Temple in dorsal view more receded (Fig. 1). Pterostigma issuing radial vein from its middle (Fig. 4). First tergite parallel-sided and clearly twice as long as broad behind (Fig. 6). First brachial cell long, four times as long as high distally (Fig. 5, see arrows). Hind femur five times as long as broad medially, hind tibia less thickening distally, i.e., ten times as long as broad apically (Fig. 3). Body rusty brown with dark brown pattern. Male: 3 mm.

Naumann (Canberra) who kindly made it possible for me to study the Taphaeus specimen housed in the Australian National Insect Collection, Canberra.
