description: Key to genera of SW Pacific Micropterigidae
1. Hindwing with R1 vein distinct in basal half (Fig. 4 B) or ‘recurrent’ (Fig. 4 D); antennal scape greatly swollen with distinct indentation on its mesal surface (Fig. 3 D); antennal ascoids radial, the sensory branches radiating from a circular base (Fig. 5 A) (‘sabatincoid’) ............................................................................................................................ 2
- Hindwing without a separate R1 vein (Fig. 4 C); antennal scape swollen and barrel-shaped, either without or with just the barest trace of an indentation (Fig. 3 B); antennal ascoids linear, the sensory branches arising out of a transverse groove around the circumference of the flagellomere (Fig. 5 C) (‘Australian-group’) ................................................ 4
2. Forewing R1 simple, unforked (Fig. 4 A); ventral part of male segment 9 sclerite shorter than sternite 6 (Fig. 8A) (north-eastern Australia) ............................................................................................ Austromartyria Gibbs, gen. nov.
- Forewing R1 forked (Fig. 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 A–H); hindwing with Sc+R1 forked (Fig. 4 C) ..............................................................................................................................................................
- Forewings pale shining ochreous, fasciae black or brown (Figs 2 C–E); hindwing with Sc+R1 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 C & D); female segment 9 largely membraneous, with a narrow ring sclerite, often almost non-existant dorsally (Fig. 10 F) (eastern Australia) ...................................... ............................................................................................................................................ Tasmantrix Gibbs, gen. nov.
- Tegulae with flat lamellar scales; male phallus with dorsal gonopore, wide, heart-shaped (Fig. 13E); female segment 9 entirely membraneous, the position of ring sclerite marked by a circle of macrosetae (Fig. 13F) (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 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 C); male genitalia not visible externally (New Caledonia) ............................................................................................................ Nannopterix Gibbs, gen. nov.
