The group is known for its abdomen which can curl dorsally &gt;90\u00b0 relative to the body axis. Proceratium includes 130 described species worldwide. In China, seven species have been recorded, yet recent surveys repeatedly reveal morphologically distinctive undescribed taxa, indicating a still-underestimated diversity of Proceratium. In this study, seven known Chinese species of the ant genus Proceratium Roger, 1863 are reviewed: P. bruelheidei, P. itoi, P. japonicum, P. kepingmai, P. longmenense, P. shohei and P. zhaoi. The species P. longigaster is removed from the ant fauna of China. Additionally, seven new species are described: P. crassopetiolum\u00a0sp. nov., P. digitospinum\u00a0sp. nov., P. planodorsum\u00a0sp. nov., P. quandratinodum\u00a0sp. nov., P. rugiceps\u00a0sp. nov., P. shanyii\u00a0sp. nov., and P. spinosubum\u00a0sp. nov. An illustrated key to Chinese species based on workers is also provided.<\/jats:p>","DOI":"10.3390\/insects16101060","type":"journal-article","created":{"date-parts":[[2025,10,17]],"date-time":"2025-10-17T10:28:36Z","timestamp":1760696916000},"page":"1060","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Synopsis of Ant Genus Proceratium Roger, 1863 from China (Hymenoptera, Formicidae), with Description of Seven New Species"],"prefix":"10.3390","volume":"16","author":[{"given":"Zhuojian","family":"Gu","sequence":"first","affiliation":[{"name":"Key Laboratory of Ecology of Rare and Endangered Species and Environmental Protection (Guangxi Normal University), Ministry of Education, Guilin 541004, China"},{"name":"Guangxi Key Laboratory of Rare and Endangered Animal Ecology, Guangxi Normal University, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Ecology of Rare and Endangered Species and Environmental Protection (Guangxi Normal University), Ministry of Education, Guilin 541004, China"},{"name":"Guangxi Key Laboratory of Rare and Endangered Animal Ecology, Guangxi Normal University, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhilin","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Ecology of Rare and Endangered Species and Environmental Protection (Guangxi Normal University), Ministry of Education, Guilin 541004, China"},{"name":"Guangxi Key Laboratory of Rare and Endangered Animal Ecology, Guangxi Normal University, Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"131","DOI":"10.1002\/mmnd.18630070116","article-title":"Die neu aufgef\u00fchrten Gattungen und Arten meines Formiciden-Verzeichnisses nebst Erg\u00e4nzung einiger fr\u00fcher gegebenen Beschreibungen","volume":"7","author":"Roger","year":"1863","journal-title":"Berl.
