Mean length 0.82 mm (0.76–0.88; n = 5); body and head brown, legs and antennae yellow, both with darker markings on dorsal surfaces. Head 2.63 (2.33–2.80) x as wide as inter-ocular distance, and 1.71 (1.52–1.83) x as wide as long; medial ocellus 15 μm in diameter, 106 (90–120) μm from posterior head margin; lateral ocelli touching eye margin, 24 (20–30) μm from posterior head margin; posterior ocellar line 1.38 (1.27–1.47) x inter-ocular distance; vertex coriarious, pilosity mostly dense, may have patches of moderate density, length generally of medium length, although some rows can exhibit short setae towards the anterior regions of the vertex; eyes large and ovoid, eye height 0.58 (0.56–0.61), eye width 0.58 (0.50–0.61) x length, pilosity short; frontal carina prominent, reaching 0.56 (0.50–0.67) distance to medial ocellus; lateral cristulations of malar region reaching to within 10 μm of eye margin; in postero-lateral view, anterior and posterior genal margins parallel medially; anterior genal margin in contact with 0.51 of ventral eye margin length; posterior eye margin touching hyperoccipital carina. Mesosoma. Length 0.63 (0.61–0.64) x width; mesoscutum and mesoscutellum coriarious, pilosity mostly of moderate density, and of medium length but can be long in parts; propodeum glabrous medio-dorsally; mesoscutum length 0.43 (0.42–0.44) x width, 0.63 (0.61–0.65) x mesosoma length and 2.44 (2.20–2.80) x mesoscutellum length; mesoscutellum 2.33 (1.67–2.50) x as long as propodeum; sculpturing of dorsal mesopleuron scrobiculate, sculpturing extending ventral to level of dorsal metapleuron; sculpturing of laterodorsal propodeum around spiracle mostly smooth with few fine setae present; propodeal spiracle opening small and ovoid, situated on lateral margin of dorsal propodeum (Fig. 13 C), which is delineated from lateral propodeum by distinct, laterally projecting carina (Fig. 13 D; large arrow); distinctive quarter-circle shaped recess present below lateral carina (Fig. 13 D; small arrow); posterior margin of metapleuron curving dorsally, ending ventral to level of antero-lateral margin of T 2, posterior region level with anterior region of lateral propodeum, depression present in medial region of posterior metapleuron and anterior propodeum; hind femoral spine reduced. Metasoma. T 2 length 0.87 (0.83–0.89), sculpturing coriarious; pilosity generally of moderate density medio-anteriorly, but sparse elsewhere, and mostly long in length, but can be of medium length in parts; both T 3 and T 4 smooth, non-pilose medially.

Discussion

Comments. Notable features of this species are the propodeal spiracle being situated close to the lateral margin of the laterally projecting carina, and the distinctive quarter-circle shape of the recess below this lateral carina. It is confined to north eastern Australia (Fig 17 A). The name ' spirolimbus' is from the Latin words that relate to the closeness of the propodeal spiracle to the lateral margin of the lateral carina; spiro, meaning breathe, and limbus, meaning fringe.
