The genus Latouchia Pocock, 1901 (Araneae: Mygalomorphae: Halonoproctidae: Ummidiinae) includes 21 species and 1 subspecies occurring in southeast Eurasia. Just like other trapdoor spiders, the specimens of Latouchia are rare in collections, unless from targeted collecting. Two new species of mygalomorph spiders, Latouchia rufa sp. n. from Guangdong, China and L. yejiei sp. n. from Hainan, China, are described and illustrated from both sexes. Diagnostic characters of the two species are provided.

An unexpected troglobitic staphylinid is described from a dolomite cave in western China as Domene lizeyui Wang & He, sp. nov. (Coleoptera, Staphylinidae, Paederinae). The habitus of both sexes and important diagnostic features are illustrated. Brief notes on the habitat, biology and taxonomic status of the new species are provided. This is the first discovery of a troglobitic representative of Paederinae from China, the first record of a troglobitic Domene species, and only the third cavernicolous species of Paederinae from eastern Asia.

The tribe Polyneurini Amyot & Audinet-Serville, 1843 (Hemiptera: Cicadidae: Cicadinae) is a small tribe which includes four genera and 18 species, distributing in eastern Palaearctic and Oriental Regions. Most of them, four genera and 16 species, are known from China. A remarkable new species of cicada, Polyneura guoliangi sp. n. (Hemiptera, Cicadidae, Cicadinae), is described and illustrated from Yunnan, southwest China. The diagnostic characters of the new species are compared with allied species or genera.

Cochleopsaltria Pham & Constant, 2017 (Hemiptera, Cicadidae, Cicadinae) is no longer monospecific: C. huboliaosp. nov. from Fujian Province of China is described and illustrated. A key to the two species of Cochleopsaltria is presented.

A new species of longhorn beetle, Anoplophora puxian sp. n. (Coleoptera, Cerambycidae, Lamiinae, Lamiini) is described from Sichuan, China. It is closely related to A. freyi (Breuning, 1947). Diagnostic characters of the two species are illustrated and compared.

Two new species of starry longhorn beetles are described from China, i.e. Anoplophora iadina sp. nov. from Yunnan and A. zibroides sp. nov. from Hunan and Guangxi. Color plates are presented to illustrate their diagnostic characters.
