This dataset contains the digitized treatments in Plazi based on the original journal article Liu, Lin, Wei, Meicai (2026): A new genus with three new species of Cephinae (Hymenoptera: Cephidae) from southwestern China. European Journal of Taxonomy 1048: 164-176, DOI: 10.5852/ejt.2026.1048.3243, URL: europeanjournaloftaxonomy.eu/index.php/ejt/article/download/3243/14359 Abstract. A new genus of Cephidae, Curvicephus gen. nov., together with three new species – C. dianzang gen. et sp. nov., C. xiaoi gen. et sp. nov., and C. lii gen. et sp. nov. – is described from Yunnan and Xizang, China.

The new genus differs from all other known genera of the family by a combination of distinctive features: an elongate ovipositor sheath distinctly and evenly bent upwards; the lateral ocelli positioned behind the line connecting the posterior margins of the eyes; the distance between the antennal toruli narrower than the distance between the inner orbits and the torulus, and about half the distance between the antennal torulus and the anterior tentorial pit; claws quite slender with the inner tooth much longer than apical tooth; head with a distinctly concave area above the antennal toruli; abdomen long and slender.
