Abstract: | A cladistic analysis of the species of Nipponoserica Nomura, 1972, was executed using 36 morphological characters of adults. From the generated phylogenetic tree, the monophyly of the genus is supported, when Pseudosericania Kobayashi, 1980 is included. Consequently, Pseudosericania Kobayashi, 1980 is considered a junior subjective synonym of Nipponoserica Nomura, 1972. Interestingly, the analysis indicates the monophyly of the East Asian Nipponoserica and the North American Stilbolemma. A new genus, Xenoserica gen. nov., is established for the basal monophyletic clade found for the Himalayan species so far assigned to Nipponoserica including the first brachypterous species of Sericini from the Himalaya. Two new species are described: Xenoserica brachyptera sp. nov. from Nepal, and Nipponoserica dahongshanica sp. nov. from Hubei (China). |
