Fourteen species of Aprostocetus Westwood from China are reviewed, including one new species, A. maculosussp. nov., and new country records for four species: A. viridinitens Graham, 1987, A. occidentalis Graham, 1987, A. ligus (Walker, 1839) and A. percaudatus (Silvestri, 1920). New distributional data for A. caudatus Westwood, 1833, A. epicharmus (Walker, 1839), A. gratus (Giraud, 1863), A. minimus (Ratzeburg, 1848), A. microcosmus (Girault, 1917), A. pinus Li & Xu, 2014, A. nigroplaque Yang & Cao, 2015, A. crino (Walker, 1838), and A. mandanis (Walker, 1839) are provided. Keys to Chinese subgenera of the genus Aprostocetus and Chinese species of the subgenera Aprostocetus and Ootetrastichus are given based on Chinese material.

Six species of Quadrastichus Girault (Eulophidae: Tetrastichinae) from China are reviewed, including three new species: Q. longisetasp. nov., Q. flavomaculatussp. nov., Q. longiscapussp. nov. and one new country record, Q. vacuna (Walker, 1839). New distributional data for Q. anysis (Walker, 1839) and Q. sajoi (Szelényi, 1941), and a key to the Chinese species of Quadrastichus based on females, are included.

In this paper, four species of Omphale Haliday, O. longigena Li & Li, sp. nov., O. longitarsus Li & Li, sp. nov., O. rectisulcus Li & Li, sp. nov., and O. xanthosoma Li & Li, sp. nov., are described as new to science; four species, O. brevibuccata Szelényi, O. connectens Graham, O. melina Yefremova & Kriskovich, and O. obscura (Förster) are reported from China for the first time; and the male of O. melina is reported for the first time in the world. A key to all known species of the genus Omphale in China is provided.

Seven species of Neotrichoporoides Girault from China are reviewed, including two new species: N. basiflavus sp. nov., N. flavothorax sp. nov. and two new country record species: N. cavigena Graham, 1991, N. szelenyii (Erdös, 1951). New distributional data for N. mediterraneus Graham, 1986, N. nyemitawus (Rohwer, 1921) and N. viridimaculatus (Fullaway, 1955) are provided and a key to Chinese species is given based on females.

Based on the examination of specimens housed in several scientific collections, we expand the known tiger beetle fauna of China, and eight species are recorded from China for the first time. The occurrence of Cicindela (Cicindela) sachalinensis raddei Morawitz, 1863 in Shanxi Province, and Neocollyris (Neocollyris) saphyrina (Chaudoir, 1850) in China are re-established. We provide distribution maps and habitus photographs of examined specimens for the newly recorded and revised species. We also discuss potential research hotspots for future taxonomic studies of tiger beetles in China.

Oomyzus flavotibialis sp. nov. is described from Liaoning and Shandong provinces, China. Oomyzus gallerucae (Fonscolombe) is reported for the first time from China. A key to Chinese species of Oomyzus is provided.
