of bark lice belonging to the suborder

Trogiomorpha Trogiomorpha is one of the three major suborders of barklice, booklice, and parasitic lice in the order Psocodea (formerly Psocoptera), alongside Troctomorpha and Psocomorpha. There are about 8 families and more than 430 described species in Trog ...

. Colloquially, Lepidopsocidae are referred to as the Scaly-winged Barklice. There are more than 220 species described worldwide.

Phylogenetic In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical dat ...

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 In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zool ...
