description: Key to Ukrainian genera of Chrysopidae 1. Intramedian cell <i>(im)</i> of fore wing is nearly trapeziform (FIg. 5a).............................................. <i>Italochrysa</i> — Intramedian cell <i>(im)</i> of fore wing is nearly oval-triangular (FIg. 5a–6c)......................................................2 2. Fore wing longer than 16 mm and more...........................................................................................................3 — Fore wing shorter than 15 mm...........................................................................................................................5 3. Setae in costal sector short and arranged at an acute angle (30–45°) to the costal vein (C)........... <i>Ninet&amp;acy;</i> — Setae in costal sector are long and arranged at an angle from 60° to almost 90° to the costal vein (C)...... 4 4. Long setae along the costal vein <i>(C)</i> of fore wing arranged almost at right angle................. <i>Chrysotropia</i> — Setae along the costal vein <i>(C)</i> of fore wing at an angle of not more than 60° (FIg. 7)............................... 9 5. Index of length to width ratio in the second cell of radial sector <i>(r 2</i> ) is 1.6 or less.................................... 6 — Index of length to width ratio in the second cell of radial sector (<i>r 2</i> ) exceeds 1.8..................................... 7 6. The cell <i>m 2</i> nearly pentagonal, less than 2.5 (usually 2 times) as long as wide; cell <i>m 3</i> nearly triangular in shape, almost as long as wide (FIg. 5c). Head and sometimes body with dark spots................... <i>Chrysopa</i> — The cell <i>m 2</i> nearly quadrangular, more than 2.5 (usually 3 times) as long as wide; cell <i>m 3</i> twice as long as wide (FIg. 6c). Head and body are without dark spots.............................................................. <i>Cunctochrysa</i> 7. First cross vein between <i>R s</i> and <i>&amp;Mcy; (r-m)</i> meets vein <i>M</i> at some distance from the apex of intramedian cell (<i>im</i>) (FIg. 6a). Cross veins of the costal sector dark colored at their ends. Thorax and abdomen without longitudinal dorsal pale band................................................................................................... <i>Pseudomallada</i> — First cross vein between <i>R s</i> and <i>&amp;Mcy; (r-m)</i> meets vein <i>M</i> slightly beyond the limits of the intramedian cell (<i>im</i>) (FIg. 6b). Cross veins of the costal sector uniformly greenish. Thorax and abdomen with longitudinal dorsal pale band............................................................................................................................... <i>Chrysoperla</i>
