Undulopsychopsis is an extinct genus of lacewing in the family silky lacewing family Psychopsidae. The genus is solely known from a Cretaceous fossil found in China. Currently the genus is composed of a single species, Undulopsychopsis alexi.
Undulopsychopsis alexi is known only from one fossil, the part and counterpart holotype, specimen number CYNB044, which is housed in the collections of the Chaoyang Bird Fossil National Geopark Chaoyang, Liaoning, China. The specimen is preserved as a compression fossil in silty yellow to grayish mudstone, dating from the Lower Barremian to Upper Aptian in age, which was recovered from outcrops of the Yixian Formation.Undulopsychopsis was first studied by the paleoentomologists Yuanyuan Peng and Dong Ren from the Capital Normal University in Beijing with Xiaodong Wang from Chaoyang Bird Fossil National Geopark and Vladimir N. Makarkin of the Far Eastern Branch of the Russian Academy of Sciences. Their 2011 type description of the new genus and species was published in the online journal ZooKeys. The genus name Undulopsychopsis was coined by the researchers as a combination of the silky lacewing type genus Psychopsis and the Late Latin word undula meaning "small wave" which is in reference to the distinctly wavy nature of the wing margins. The specific epithet alexi is in honor of the distinguished Russian paleoentomologist Alexandr Pavlovich Rasnitsyn.
