Length of fore wing is more than 3 cm............................................................................................................ 2 — Length of fore wing less than 2 cm....................................................................................................................3 2. Width of cubital sector more than 0.2 (c. 0.25) of fore wing width. Veins <i>Sc</i> and <i>R</i> fused into smooth curve towards the wing tip; distal cell between <i>R</i> and <i>Rs</i> is elongated, being 4–7 times as long as wide (FIg. 3a). Antenna gradually thickening towards the tip or clavate.................................... Myrmeleontidae — Width of cubital sector less than 0.15 (usually 0.1) of fore wing width. The vein <i>Sc+ R</i> right after fusing steeply bent backwards; distal cell (FIg. 3b) between <i>R</i> and <i>Rs</i> short, quadrangular or nearly square, being 1.5 times as long as wide. Antenna clavate, long......................................................................... Ascalaphidae 3. Radial sector always includes three cells; <i>R</i> vein forming <i>Rt</i> (radial triangular) in front of the FIrst <i>Rs</i> (FIg. 3f). Fore leg raptorial............................................................................................................... Mantispidae — Radial sector always includes more than three cells; <i>R</i> vein not forming <i>Rt</i> (radial triangular). Fore leg walking...................................................................................................................................................................3 4. Fore wing longer than 1.2 cm.............................................................................................................................6 — Fore wing shorter than 1 cm.............................................................................................................................11 5. Wing membrane transparent with many dark spots, main veins brownish. Veins <i>Sc</i> and <i>R</i> fused gradually towards wing tip (FIg. 3c). Head with three simple ocelli.............................................................. Osmylidae — Wing membrane transparent without spots, main veins greenish (yellowish in dry specimens). Veins <i>Sc</i> and <i>R</i> fused at the wing tip, or joined by cross veins, if not fused (FIg. 3d). Head without simple ocelli......................................................................................................................................................................................... Chrysopidae 6. Fore wing longer than 0.6 cm........................................................................................................................... 7 — Fore wing shorter than 0.5 cm.........................................................................................................................13 7. Wing membrane transparent, often with dark spots or characteristic drawings. Fore wing with two or more branches <i>Rs</i>; <i>Sc</i> and <i>R</i> terminate separately. Radial sector with many cross veins. Numerous <i>trz</i> are clearly visible on wing edges (FIg. 3h)......................................................................................... Hemerobiidae — Wing membrane transparent, uniformly brownish colored, lacking spots and pattern. Fore wing with only one branch <i>Rs; Sc</i> and <i>R</i> are fused near wing tip, vein <i>Sc</i> is steeply curved before fusion with <i>R</i> (FIg. 3e). Radial sector includes few cross veins. Wing edges lacking <i>trz.</i>..................................... Sisyridae 6. Body and wings covered with white wax-like coating. Wings lack setae and spots. Venation simple: few cross veins, not more than 5; costal sector lacking cross veins; longitudinal veins without branching (FIg. 3g). Female ovipositor lacking....................................................................................... Coniopterygidae — White wax-like coating lacking. Wings covered with long dense setae, usually with characteristic drawings, including numerous brown spots and stripes. Venation is dense and complex: many cross veins. Female has a long saber-like ovipositor.................................................................................. Dilaridae
