First record of Liposcelis entomophila(Enderlein)(Psocodea: Liposcelididae) from Sri Lanka based on morphological and molecular data

The booklice genus, Liposcelis(Psocodea: Liposcelididae), owns some stored product pests and have economic importance. In this study, 6 booklice specimens from Sri Lanka were collected and identified based on morphological and molecular data. According to the morphological and phylogenetic analyses, the samples were identified as Liposcelis entomophila. The mitochondrial gene cytochrome c oxidase I(COI) and second internal transcribed spacer(ITS2) were sequenced for phylogenetic work. The phylogenetic trees show that the samples assemble with L. entomophila together and could be distinguished with other Liposcelis spp. apparently. The genus Liposcelis and the species L. entomophila are firstly reported in Sri Lanka.
