First biological report on the genus Cantonius (Buprestidae, Agrilinae, Aphanisticini), with descriptions of two new species from China

Abstract

The genus Cantonius Théry, 1929 is a small group with two subgenera and 12 species. However, the biology of this genus is still unknown.In this paper, three species of the genus Cantonius Théry, 1929 were found on bamboo leaves, revealing for the first time that Cantonius species are also leaf-miners. Two new species were recorded from Jiangxi Province and are described here: Cantonius (Cantonius) anjiensis sp. n. (host plant: Pleioblastus amarus) and Cantonius (Procantonius) qiyunensis sp. n. (host plant: Bambusa blumeana) followed by C. (P.) austrisinicus Kalashian, 2021 (host plant: Oligostachyum paniculatum) recorded from Guangxi Province. Including habitats, photos of three species together with C. (P.) qiyunensis sp. n. pupa, host plants, and leaf mines of the three species are presented. Moreover, the bionomics and habits of the genus are discussed for the first time, and a hypothesis for the distribution of Cantonius is provided.
