Type material.

Holotype female (QMBA) on slide (Fig. 107 ), labelled: 1. "Mt. Glorious, S.E. Qld. Hiller March 1982 Malaise trap". 2. " Neotriadomerus gloriosus Huber ♀ dorsal holotype".

Diagnosis.

Neotriadomerus gloriosus differs from the other small (body length less than 2600) species of Neotriadomerus , as follows: fore wing with cubital line extending to just proximal to base of parastigma (Fig. 103 ); fl2-fl5 each at least 2.0 × as long as wide and with at most 6 long mps in 1 whorl (Fig. 102 ).

Description.

Female. Body length ≈ 1840 (holotype). Colour. Holotype body almost uniformly dark brown; legs brown, with trochantelli, base and apex of femora and entire protibia, and base and apex of meso- and metatibiae, and tarsi except tarsomere 5 paler, almost white; tarsomere 5 brown. Head. Head width 374 (Figs 100 , 101 ). Antenna. Fl1 about 0.7 × as long as fl2, with 4 mps; fl2 slightly the longest funicle segment, with 8 mps; fl3-fl8 with 8 (9? on fl8) mps; clava with about 18 mps, 8 on first, 4 on second and 6 (8?) on third segment (Fig. 102 ). Antennal measurements (n=1), length/width (ratios of flagellar segments, different for each antenna so left antenna, except scape of right antenna, measured-the left antenna has narrower funicle segments): scape 152/49 (3.10), pedicel 57/43 (1.32), fl1 91/50 (1.84), fl2 118/48 (2.47), fl3 114/46 (2.48), fl4 111/46 (2.43), fl5 105/46 (2.29), fl6 99/45 (2.21), fl7 99/47 (2.09), fl8 92/46 (1.98); entire clava 148/52 (2.82), with segments 1-3 length [measured along dorsal margin] 56, 28, and 64. Mesosoma. Width 324, length 711, with 2 propodeal setae (Fig. 104 ). Wings. Fore wing length 1367, width 486, length/width 2.81, longest marginal setae 77; cubital line extending to just proximal to base of parastigma (Fig. 103 ). Hind wing length 1109, width 157, longest marginal setae 78. Legs. Protibia with 6 or 7 short, thick pegs along its length and a transverse row of 4 abutting pegs apically (as in Fig. 53 ). Metasoma. Metasoma height in lateral view 225 (excluding lowered hypopygium) (Figs 105 , 106 ). Gaster length 1002, about 1.41 × as long as mesosoma; gt1-gt7 lengths about 170: 166: 151: 118: 130: 209 [measurement of a tergum excludes the telescoped portion inside another (more anterior) tergum]; hypopygium extending posteriorly to about level of spiracle. Ovipositor sheath length 1274, ≈ 2.54 × metatibia length (≈ 502), extending anteriorly to about level of apex of procoxa and extending posteriorly only slightly beyond apex of gaster (Fig. 105 , 106 ) [apparently extending more than normal because ovipositor not at its normal resting position, i.e., filling entire length of basal sac of gaster, whose almost membranous apex is distinctly folded over (Fig. 105 , arrow)].

Male. Unknown.

Etymology.

The species is named after the type locality, Mt. Glorious National Park.
