Abstract Thirty species in 13 genera of plant bugs (Phylinae: Phylini) from Nepal are revised in a first attempt to comprehensively clarify the fauna from this country. Five new genera, Alnopsallus, Aplagiognathus, Leucophylus, Psallomorpha and Zanchiophylus, are proposed. The following 21 species are described as new: Alnopsallus godawari, Al. jiriensis, Aplagiognathus albopilosus, Atractotomoidea monticola, At. orientalis, Campylomma buddlejae, C. chitwanense, Decomia bhaktapurana, Europiella langtangensis, E. puspae, Leucophylus variegatus, Moissonia schuhi, M. terai, Psallomorpha alba, P. castanopsis, P. kathmandu, P. quercicola, P. tenella, P. tomokunii, Rubrocuneocoris nigriceps, and Zanchiophylus hyaloviridis. Nine described species of the genera Badezorus, Campylomma, Decomia, Opuna, and Moissonia are reported from Nepal for the first time and are diagnosed. Opuna pallidula Yasunaga is proposed as a junior synonym of Moissonia importunitas (Distant). Digital photographic images of live individuals...
