The subgenus Nippocallis (Matsumura, 1917) is one of the 10 subgenera of the genus Tuberculatus Mordvilko, 1894. Originally, this subgenus was regarded as an independent genus of the subtribe Myzocallidina by the distinct morphological features and the host plant association with Castanea (Fagaceae). We performed molecular and morphological analyses to determine whether genus Nippocallis belongs to Tuberculatus group. Molecular analysis of the combined data set of Cytochrome Oxidase subunit I COI, Cytochrome B CytB and Elongation Factor I-alpha EF1α indicated that Nippocallis form a sister clade of the genus Myzocallis Passerini, 1860, apart from the genus Tuberculatus. In this contexts, we propose Nippocallis as a separate genus of the subtribe Myzocallidina.
