The parthenogenetic psocid Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae) is regarded as the common stored product pest in the world. This species has been identified as a new record in People's Republic (P.R) of China in this study. It was found in a sample of rice sweepings at grain storage in Lijiang, Yunnan, 2010. Decisive morphological characteristics of this new record species were described in detail and newly documented by scanning electron microscopy (SEM) micrographs. In the meantime, DNA barcode sequences of mtDNA COI of this geographical strain were tested and analyzed by neighbor-joining phylogenetic tree which showed that it was in the same sub-group with the U.S.A. stock. The origin of L. reticulatus and the necessity of continued comprehensive survey of stored product psocids were discussed.
