Type material.
Holotype female (ANIC) on slide (Fig. 84 View Figures 83–86 ), labelled: 1. "Australia: Sth Aust. 32 km N. Renmark, 263m 33°53'S, 140°43'E, 15.ii-15.iv.2000, DC Darling". 2. "Bookmark Biosphere Rsv. Malaise trps (4) Amalia Dam xeric mallee scrub ROM 2000040". 3. " Neotriadomerus darlingi Huber Holotype ♀ dorsal".
Paratypes. 3 females, 1 male. AUSTRALIA. South Australia: Same locality data as holotype (1 ♀ and 1♂, ROM, CNC); 35 km N Renmark, 263m, 33°52'48"S; 140°43'30"E, 11-14.ii.2000, D.C. Darling, Bookmark Biosphere Reserve, Malaise trap, Amalia Dam, mallee vegetation, ROM 2000030 (1♀, ANIC). Western Australia: 85 km E. Southern Cross, Boorabbin National Park, 28.xii.1986, J.S. Noyes (1♀, BMNH)
Two males with the following data questionably belong to this species so are not labelled as paratypes. They were collected from South Australia, Brookfield Conservation Park, 34.21°S, 139.29°E, 17 & 18.ii.1992, J. Cardale, A. Roach, light trap (2♂, ANIC) and one is illustrated (Figs 93 View Figures 93–96 - 99 View Figures 97–99 ). Both sexes need to be collected together from Brookfield Conservation Area to be more certain of their conspecificity with the holotype.
Diagnosis.
Neotriadomerus darlingi differs from the other small (body length less than 2600) species of Neotriadomerus as follows: fore wing with cubital line extending proximally to about level of other microtrichia (Fig. 86 View Figures 83–86 ); funicle segments with at most 6 mps (Fig. 85 View Figures 83–86 ); ovipositor 2.57-2.74 × as long as metatibia (Fig. 92 View Figures 90–92 ).
Description.
Female. Body length 1420-1560 (n=2, card-mounted paratypes). Colour. Body (Fig. 81 View Figure 81 ) almost uniformly dark brown; fore leg yellow except procoxa brownish basally, ventral surface of profemur and tarsomere 5 brown; middle and hind legs lighter brown with trochantelli, base and apex of femora and entire protibia, base and apex of meso- and metatibiae, and tarsi except tarsomere 5 paler, almost white; metafemur medially and tarsomere 5 brown; ovipositor sheath with lighter band subapically (Figs 81 View Figure 81 , 88 View Figures 87–89 , 89 View Figures 87–89 ). Head. Width ≈ 320-346 (card-mounted) and 358 (slide mounted specimen from WA, Figs 90 View Figures 90–92 , 91 View Figures 90–92 ). Antenna. Fl1 slightly shorter than to almost equal to fl2, with 5 mps (Fig. 85 View Figures 83–86 ); fl2-fl8 with 6 mps. Clava with 10 or 11 mps, 5 or 6 on first, 2 on second and 4 on third segment. Antennal measurements (n=2, first number is for the holotype, a slightly smaller specimen), length/width (ratio of flagellar segments): scape 124-126/37-40 (3.37-2.51), pedicel 50-56/39-41 (1.29-1.36), fl1 70-74/38-45 (1.85-1.65), fl2 80-75/34-40 (2.36-1.88), fl3 77-76/34-38 (2.26-1.97), fl4 78-75/35-38 (2.24-1.96), fl5 79-76/33-38 (2.39-2.01), fl6 76-74/33-37 (2.28-2.20), fl7 77-78/34-39 (2.23-2.13), fl8 76/34-40 (2.25-1.89); entire clava 141-142/39-42 (3.63-3.40), with segments 1-3 length [measured along dorsal margin], 48-50, 25, and 67-68.

Fore wing length 1045-1118, width 383-412, length/width 2.71-2.73, longest marginal setae ≈ 51-61; cubital line extending to just proximal to base of parastigma (Fig. 86 View Figures 83–86 ). Hind wing length ≈ 870-890, width 121-140, longest marginal setae ≈ 58-62. Legs. Protibia with 4 or 5 short, thick pegs along its length and a transverse row of 2 or 3 abutting pegs apically. Metasoma. Metasoma in lateral view 255-360 at highest point, gradually widening from petiole to about 0.4-0.7 of gaster length towards apex, then more abruptly narrowing to cerci (Fig. 89 View Figures 87–89 ). Gaster length (holotype, second measurement) 776-858, 1.18-1.36 × as long as mesosoma; gt1-gt7 lengths about ≈ 162-170, ≈ 136-144, 98-126, 113-177, 132-186, 209 -146, 53-58; hypopygium extending about 0.6 × length of gaster, about to apex of tergum 4.

Male. Body length 1330 (point-mounted paratype) and 1230 (slide-mounted specimen, Brookfield Conservation Area). Colour as for female but with legs almost entirely brown (Fig. 82 View Figure 82 ). Head. If correctly associated, as for female (Figs 93 View Figures 93–96 , 94 View Figures 93–96 ). Antenna.

Etymology.
The species is named after Chris Darling, curator of Entomology at the Royal Ontario Museum, Toronto, who collected the type series.
