Key to the identification of species of the genus Chrysopa

1. Index ratio of length to width in m2 cell 2:1. .................................................................................................. 2

— Index ratio of length to width in m 2 cell 3:1. ................................................................................................... 3

2. Sc and R of fore wing not fused. Pterostigma covers 6–7 cells of costal FIeld (C) and part of Sc FIeld. Costal FIeld includes 32–33 cells. Inner and outer gradates of the fore wing are black colored ( FIg. 8 ). ................ .................................................................................................................................. С. walkeri McLachlan, 1893 — Sc and R of fore wing fused in the proximal part of fore wing. Pterostigma covers 10–12 cells of costal FIeld (C). Costal FIeld includes 41–42 cells. Inner and outer gradates of the fore wing are green colored ( FIg. 9 ) ............................................................................................................................ С. pallens Rambur, 1838

3. Ratio of length to width in m 3 cell 2:1 or slightly more..................................................................................4

— Ratio of length to width in m 3 cell 1.5:1 or slightly less..................................................................................5
