( Figs 238 –251)

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, Murchison palaeovalley, Yarrabubba South calcrete, MEB site 72, BES 13100, 27.0668S, 118.6795E, 21–X–2005, coll. W. F. Humphreys and R. Leys.

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

Instar I ( Figs 238 –251). Head ( Figs 238–246 ). Cephalic capsule not strongly elongate (HL/HW less than 1.55); seta PA3 inserted far from setae PA1 and PA2; A3 2.20–2.75 times longer than A1; A3 more than 2.25 times longer than A2; MP2 less than 1.45 times longer than MP1; MP2 more than 3.30 times longer than MP3; LP2 less than 1.30 times longer than LP1. Legs (Figs 247–248). L3 less than 2.85 times longer than HW. Abdomen (Figs 249–251). U 3.60–3.70 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 14 lamellae clypeales; additional setae on U absent. Measurements and ratios that characterize the body shape are shown in Table 4.
