Abstract
A new genus with a new species, Lasiopsychops impunctatus gen. et sp. nov., and a new species, Electropsychops oligophlebius sp. nov., of silky lacewings in Psychopsidae are described from mid-Cretaceous Burmese amber. Lasiopsychops gen. nov. has typical characters of the extant Psychopsidae, i.e., broad triangular forewing, broad costal space, presence of the vena triplica and the paired ectoprocts and gonocoxites 9 of female genitalia, implying its close affinity with the extant lineages of Psychopsidae. The new findings of the Cretaceous psychopsids enhance our knowledge on the diversity and evolution of Psychopsidae during the Mesozoic.
