( Figs 180–193 View FIGURES 180–188 View FIGURES 189–193 )

Source of material. One specimen of instar I was used for the description ( Table 1). The larva was collected in association with adults at the following locality: Australia, Carey palaeovalley, Mounth Windarra calcrete, MEB site 73, BES 10292, 28.39652S, 122.19766E, 20–III–2004, coll. W. F. Humphreys and S. J. B. Cooper. GoogleMaps

Diagnosis. No diagnosis is provided owing to a lack of specimens of instars II and III.

Instar I ( Figs 180–193 View FIGURES 180–188 View FIGURES 189–193 ). Head ( Figs 180–188 View FIGURES 180–188 ). Cephalic capsule not strongly elongate (HL/HW less than 1.55); seta PA3 inserted far from setae PA1 and PA2; A3 less than 2.15 times longer than A1; A3 (instar I): (0) less than 2.05 times longer than A2; MP2 less than 1.45 times longer than MP1; MP2 1.95–2.65 times longer than MP3; LP2 less than 1.30 times longer than LP1. Legs ( Figs 189–190 View FIGURES 189–193 ). L3 less than 2.85 times longer than HW. Abdomen ( Figs 191–193 View FIGURES 189–193 ). U more than 3.75 times longer than LAS; U less than 2.35 times longer than HW; U1 more than 1.45 times longer than U2. Chaetotaxy. Frontoclypeus with 12 lamellae clypeales; additional setae on U present. Measurements and ratios that characterize the body shape are shown in Table 3.

Instar II. Not available.

Remarks. The species is not diagnosed above because of lack of instars II and III. However, it can be separated from all the other species described as instar I by the presence of additional setae on the urogomphus ( Fig. 193 View FIGURES 189–193 ), a unique feature within the taxa examined, and by the combination of characters given under the description.
