Background: Chrysochroinae Laporte de Castelnau, 1835 is the very colourful subfamily of Buprestidae. There are 127 species and subspecies of the subfamily which have been recorded in China. New information: In this paper, we reported three genera, two subgenera and five species of the subfamily Chrysochroinae Laporte de Castelnau, 1835 (Coleoptera, Buprestidae) which are all newly recorded from China. These reported taxa belong to two tribes and four genera: Chrysochroa (Chroodema) corbetti (Kerremans, 1893), Chrysochroa (Pyranthe) fulgens ephippigera White, 1843, Demochroa (Demoxantha) gratiosa indica Csiki, 1900, Xanthocata bonvouloirii (Deyrolle, 1861) (all the above four being Chrysochroini) and Cardiaspis mouhotii E. Saunders, 1866 (Dicercini). The five newly-recorded species are briefly described, illustrated and supplemented with relevant biological information. [ABSTRACT FROM AUTHOR]

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]

A new species Coomaniella (Coomaniella) dentata sp. nov. from Guangxi Province, China, is described and placed in the C. (C.) chinensis species-group. The variability is discussed, and a new adult host plant is recorded. New distributional records are given for C. biformissima Jendek & Kalashian, 1999 and C. lingafelteri Jendek & Pham, 2013.

Oomyzus spiraculus Song, Fei & Cao sp. nov. (Hymenoptera, Eulophidae) is described and illustrated as a gregarious larval-pupal endoparasitoid of Coccinella septempunctata L. (Coleoptera, Coccinellidae). Differentiation between O. spiraculus and its similar species is discussed and a key to differentiate the female and male of these species is provided. DNA barcodes of O. spiraculus and O. scaposus are analyzed and compared. [ABSTRACT FROM AUTHOR]
