Seven new species of the genus Bolitogyrus Chevrolat, 1842 are described based on specimens collected in China, namely B. depressus sp. nov. from Guangdong, B. hainanensis sp. nov. and B. magnimaculosus sp. nov. from Hainan, B. metallicus sp. nov. from Hubei, and B. loculus sp. nov., B. profundus sp. nov. and B. uncus sp. nov. from Yunnan. The number of Bolitogyrus species is thus increased to 59. Line drawings and color illustrations of adults and genitalia of the new species and some others are given. A key to species known from China is provided, with the exception of B. fukienensis Scheerpeltz, 1974, which is only known from females. A geographical distribution map of all Chinese species is also compiled.

Two new species of Meleonoma Meyrick, 1914a (Gelechioidea, Xyloryctidae) from southeastern China are described: Meleonoma foliiformis Yin, sp. nov. from Guangxi Province and M. projecta Yin, sp. nov. from Fujian Province. Adults and male genitalia are described in detail. A list of the Meleonoma species occurring in China is given. The taxonomic position of Meleonoma has been unstable, and under debate. Nonetheless, it is here tentatively placed in the family Xyloryctidae, following the latest molecular phylogenetic study concerning this genus.

This study deals with the taxonomy of seven species and subspecies of the genus Paratalanta Meyrick in China. Among them, P. furcata sp. nov. and P. annulata sp. nov. are described as new. The male of P. stachialis Toll & Wojtusiak, 1957 is described for the first time. Images of adults and illustrations of both male and female genitalia are provided, along with a key to all the known Chinese species and a map showing their distribution.

A male of the very rare and phylogenetically puzzling species, Quelaestrygon puetzi Smetana, 1999, is described for the first time based on a single specimen from Sichuan Province, China. High quality color images and line drawings of the male external and genitalic traits are provided.
