The stick insect fauna of Laos has been poorly studied to date. Only 4 species are recorded from the country: Medauroidea brongniarti (Brunner von Wattenwyl, 1907), Phobaeticus magnus Hennemann & Conle, 2008, Parapachymorpha spiniger (Brunner von Wattenwyl, 1907), Sipyloidea sipylus (Westwood, 1859). Assessment of their actual species richness is impeded by various unfavorable circumstances. Their cryptic and immobile lifestyle does not allow for easy trapping and collecting. The aim of this study is to update the taxonomic status of the order Phasmatodea in Laos for the future study.

Some species of the genus Nemapogon Schrank, 1802 (N. granella, N. cloacella, and N. variatella) are well known as storage pests and distributed worldwide (Gaedike, 2000). The larvae of these moths feed on stored food such as cereals, flour, and dried mushrooms (Robinson and Nielsen, 1993). In Korea, the genus Nemapogon have been reported only one species up to date (Byun et al., 2009), with Nemapogon granella (Linnaeus, 1758). In this study, two additional species of the genus Nemapogon Schrank are reported for the first time in Korea. The adults are briefly described and illustrated, including adults genitalia.
