Walker

1. Head strongly prolonged laterally, eyes at apices of long stalks (Figs. 57, 59, 63, 67–76, 791–82, 87–88)................ 2

- Head normal in shape.................................................................................. 3

2. Orbital and genal setae absent; eye stalk in male rather long, longer than or about equal to length of abdomen (Figs.71–74); palpus spatulate, sparsely covered with fine, yellow setulae.................................... Pelmatops Enderlein

- Orbital and genal setae present; eye stalk in male much shorter than abdomen (Figs. 81–82, 87–88); palpus narrow, parallel sided and densely covered with strong, black setulae...................................... Pseudopelmatops Shiraki

3. Head with strong and strap-like orbital seta situated close to midlength of frons (Figs. 108–109, 125, 135–137); wing with entire vein R4+5 and at least the base of vein Cu1 covered with long, conspicuous setulae.................... Soita Walker
