Lepidopsocidae are an insect family of bark lice belonging to the suborder Trogiomorpha. Colloquially, Lepidopsocidae are referred to as the Scaly-winged Barklice. There are more than 220 species described worldwide. Phylogenetic DNA analysis of relationships between families in Trogiomorpha propose that Lepidopsocidae is monophyletic, meaning that the taxa within all share a common ancestor.Yoshizawa, Kazunori, Charles Lienhard, and Kevin P. Johnson. "Molecular systematics of the suborder Trogiomorpha (Insecta: Psocodea:‘Psocoptera’)." Zoological Journal of the Linnean Society 146.2 (2006): 287-299. This is supported morphologically by the presence of scales and setae covering the body and forewings of Lepodopsocids. Sister families of Lepidoposcidae include Trogiidae and Psoquillidae.

Lepidopsocidae was described by Gunther Enderlein in The Scaly Winged Copeognatha (Monograph of the Amphientomidae, Lepidopsocidae, and Lepidillidae in relation to their Morphology and Taxonomy), published in 1906.Enderlein, Gunther. "The Scaly Winged Copeognatha (Monograph of the Amphientomidae, Lepidopsocidae, and Lepidillidae in relation to their Morphology and Taxonomy." Spolia Zeylandica 4 (1906): 39-122. Subfamilies of Lepidopsocidae include:

• Echinopsocinae Enderlein, 1906
• Lepidopsocinae Enderlein, 1903
• Lepolepidinae
• Parasoinae Mockford, 2005
• Perientominae Enderlein, 1903
• Thylacellinae Roesler, 1944
