Background: The genus Cantonius Théry, 1929 is a small group with two subgenera and 12 species. However, the biology of this genus is still unknown. New information: 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. [ABSTRACT FROM AUTHOR]

This paper presents a review of the genus Brachytrycherus Arrow from mainland China. Three new species are described and illustrated: B. bipunctatus Chang & Bi, sp. nov., B. denticulatus Chang & Bi, sp. nov., and B. humeralis Chang & Bi, sp. nov. The diagnosis, distribution, type locality, biology, and ecology are provided for each species. A key to the species of Brachytrycherus known in China is updated. [ABSTRACT FROM AUTHOR]

Two new species of the genus Solskyia, S. infossata sp. nov. and S. lhozhaga sp. nov., are described and illustrated from Xizang, China. Solskyia lhasana is redescribed and figured based on a male, and new material of S. caporiaccoi and S. parvicollis from China is documented. The ecology and biology of adults and larvae is briefly introduced. Furthermore, photographs of habitat, and a key to Chinese species are presented. [ABSTRACT FROM AUTHOR]

Empidideicus Becker, 1907 is newly recorded from China and the Oriental Region, with one new species, E. pentagonius sp. n., described and illustrated. Observations are provided on the biology of E. pentagonius sp. n. visiting flowers of Stemona mairei (Levl.) Krause (Liliflorae, Stemonaceae). A key to the genera of Mythicomyiidae known to occur in China is provided. [ABSTRACT FROM AUTHOR]

Taxonomy of a tetrigid genus Teredorus Hancock is reviewed.
