Key to genera of SW Pacific Micropterigidae

1. Hindwing with R 1 vein distinct in basal half ( Fig. 4 View FIGURE 4 B) or ‘recurrent’ ( Fig. 4 View FIGURE 4 D); antennal scape greatly swollen with distinct indentation on its mesal surface ( Fig. 3 View FIGURE 3 D); antennal ascoids radial, the sensory branches radiating from a circular base ( Fig. 5 View FIGURE 5 A) (‘sabatincoid’) ............................................................................................................................ 2

- Hindwing without a separate R 1 vein ( Fig. 4 View FIGURE 4 C); antennal scape swollen and barrel-shaped, either without or with just the barest trace of an indentation ( Fig. 3 View FIGURE 3 B); antennal ascoids linear, the sensory branches arising out of a transverse groove around the circumference of the flagellomere ( Fig. 5 View FIGURE 5 C) (‘Australian-group’) ................................................ 4

2. Forewing R 1 simple, unforked ( Fig. 4 View FIGURE 4 A); ventral part of male segment 9 sclerite shorter than sternite 6 (Fig. 8 A) (north-eastern Australia) ............................................................................................ Austromartyria Gibbs, gen. nov.

- Forewing R 1 forked ( Fig. 4 View FIGURE 4 D); male segment 9 sclerite considerably longer than sternite 6 ( New Zealand, New Caledonia) (= Sabatinca s.str. lineage)................................................................................................................................. 3

3. Labial palps 3 -segmented; male tergum 10 bilobed; female bursa usually with signa. ( New Caledonia, New Zealand) .................................................................................................................................................. Sabatinca Walker, 1863

- Labial palps 2 -segmented; male tergum 10 a simple median lobe; female bursa lacking signa. ( New Zealand only) .. ................................................................................ Palaeomicra Meyrick, 1885 (syn. Micropardalis Meyrick, 1912 )

4. Forewings dark grey to black with strong purple iridescence, fasciae white ( Figs. 1 View FIGURE 1 A–H); hindwing with Sc+R 1 forked ( Fig. 4 View FIGURE 4 C) ..............................................................................................................................................................

- Forewings pale shining ochreous, fasciae black or brown ( Figs 2 View FIGURE 2 C–E); hindwing with Sc+R 1 unforked .................. 6

5. Tegulae with tuft of long piliform scales; male phallus with terminal gonopore crescentic, both dorsal and ventral lips extended in mid-line to give a fish-mouthed shape ( Figs. 10 View FIGURE 10 C & D); female segment 9 largely membraneous, with a narrow ring sclerite, often almost non-existant dorsally ( Fig. 10 View FIGURE 10 F) (eastern Australia) ...................................... ............................................................................................................................................ Tasmantrix Gibbs, gen. nov.

- Tegulae with flat lamellar scales; male phallus with dorsal gonopore, wide, heart-shaped (Fig. 13 E); female segment 9 entirely membraneous, the position of ring sclerite marked by a circle of macrosetae (Fig. 13 F) (North Island, New Zealand) .................................................................................................................... Zealandopterix Gibbs , gen. nov.

6. Ocelli absent; forewing with an oblique brown or black transverse fascia at mid- length, often interrupted in the middle ( Figs. 2 View FIGURE 2 D & E); male genitalia clearly visible externally, one third of abdomen length (north-eastern Australia, New Caledonia) ............................................................................................................... Aureopterix Gibbs , gen. nov.

- Ocelli present; forewing without a transverse fascia at mid length ( Fig. 2 View FIGURE 2 C); male genitalia not visible externally ( New Caledonia) ............................................................................................................ Nannopterix Gibbs, gen. nov.
