Family CHRYSOPIDAE Schneider, 1851

Diagnosis. Green lacewings ( Chrysopidae ) are one of the largest families among Neuroptera . There are about 1,300 currently recognized species in the world, included in 87 genera and 3 subfamilies. The adults are mostly predators, but a few species feed on pollen. The adults have symmetrical mandibles and long setaceous antennae, which may exceed the length of the wing two times. The wings are large (hind wings slightly smaller than fore wings), semi-transparent, iridescent; veins mainly greenish or brownish. In contrast to other neuropterans, the chrysopids’ wing membrane is without microtrichia and trz. The pterostigma is not always visible. Wing veins are covered with setae on both sides, forming a dense fringe in some members of the family. The jugulum lobe of the wing is present only in the most primitive species of the family. Wings have a characteristic venation, which is of great value for identifying the taxa ( FIg. 1 ) (e. g., Aspöck & Aspöck, 2007; Zakharenko, 1993 and many others).

The family Chrysopidae includes three subfamilies: Apochrysinae, Chrysopinae , and Nothochrysinae . The distribution ranges of most members of Apochrysinae are restricted to the Southern Hemisphere: seven species of two genera are known from Central and South America; two genera with three species occur in South Africa; FIve genera with 14 species live in the Australian Region. In the Northern Hemisphere, the subfamily is represented by a single species — Nacaura matsumurae Okamoto, 1912 from Japan ( Brooks, 1997; Hölzel, 1984; Toschi, 1965; Winterton et al., 2015).
