Psychopsidae is a family of winged insects of the order Neuroptera. They are commonly called silky lacewings. The silky lacewings are distinguishable in their adult stage by their spectacularly patterned and pubescent wings, broad wing shape, dense venation, and the presence of a vena triplica (the apical fusion of three veins in the hindwing). Taxonomy They were formerly placed in the superfamily Hemerobioidea, but do not seem to be closely related to these net-winged insects at all. Rather, might be closer to the Myrmeleontoidea which contain for example the antlions (Myrmeleontidae). In particular, the spoon-winged laceflies (Nemopteridae) seem to be very closely related to the silky lacewings. These had at one time been placed in a superfamily Nemopteroidea. The fossil family Osmylopsychopidae was - as indicated by their scientific name - initially believed to be intermediate between the Psychopsidae and the Osmylidae. But actually these similarities are due to plesiomorphies in the first case, and simply misperceived in the second; the osmylopsychopids are one of the basal lineages of the Myrmeleontoidea as traditionally defined. The Nemopteroidea were eventually abolished and its members included in the Myrmeleontoidea. But as the silky and spoon-winged lacewings together with the "butterfly" lacewings of the Kalligrammatidae do seem to form a quite distinct clade among the expanded Myrmeleontoidea, it appears well warranted to reinstate the Nemopteroidea for them. Silky lacewings were especially more diverse from the Triassic period to the Tertiary than in modern times. Genera and species The family currently includes five living genera in two subfamilies; there are also a number of extinct genera with uncertain relationships. The extant species are restricted to the Afrotropical (three genera), Indomalayan (one genus) and Australasian (one genus) regions: Subfamily Psychopsinae Genus Balmes (Southwestern and Southern Asia) Balmes birmanus (McLachlan, 1891) Balmes chikuni Wang & Bao, 2006 Balmes formosus (Kuwayama, 1927) Balmes notabilis Navás, 1912 Balmes terissinus Navás, 1910 Subfamily Psychopsinae (continued) Genus Psychopsis Newman, 1842 (Australia) Psychopsis barnardi Tillyard, 1925 Psychopsis coelivaga (Walker, 1853) Psychopsis dumigani Tillyard, 1922 Psychopsis elegans (Guérin-Méneville, 1844) Psychopsis gallardi (Tillyard, 1919) Psychopsis gracilis Tillyard, 1919 Psychopsis illidgei Froggatt, 1903 Psychopsis insolens McLachlan, 1863 Psychopsis maculipennis Tillyard, 1925 Psychopsis margarita Tillyard, 1922 Psychopsis meyricki McLachlan, 1887 Psychopsis mimica Newman, 1842 Psychopsis tillyardi New, 1989 Subfamily Zygophlebiinae Genus Cabralis Navás, 1912 (central to southern Africa) Cabralis gloriosus Navás, 1912 Genus Silveira Navás, 1912 (Afrotropical) Silveira jordani Kimmins, 1939 Silveira marshalli (McLachlan, 1902) Silveira
