| Abstract: | A new genus and new species, Longilanceolatus tenellus gen. et sp. nov., is described and assigned to the tribe Vetanthocorini of the fossil family Vetanthocoridae. In addition, a new species, Curvicaudus spinosus sp. nov., is also described. All specimens were collected from the Lower Cretaceous of the Yixian Formation at Huangbanjigou, Chaomidian Village, Beipiao City, Liaoning Province, northeastern China. Body size, ovipositor length, abdomen length, and other characters of eleven genera from the Middle Jurassic to Eocene are summarized. Comparison of body size of all specimens in the Vetanthocoridae and Anthocoridae (sensu lato) indicate a general trend toward smaller body size through their evolution. Moreover, Longilanceolatus, with uniquely long ovipositor, is related to a different type of oviposition compared with extant flower bugs. |
