A new genus with a new species, Sinohelorus elegans gen. et sp. nov., is described and assigned to the subfamily Mesohelorinae, Heloridae. In addition, two new species, Gurvanhelorus beipiaoensis sp. nov. and Spherogaster saltatrix sp. nov., are also described. The diagnoses of Gurvanhelorus Rasnitsyn, 1986 and Spherogaster Zhang and Zhang, 2001 are emended based on new materials and findings. These well-preserved specimens were collected from the Jehol Biota, Early Cretaceous Yixian Formation of Huangbanjigou Village in Liaoning, China. These new species broaden the diversity of this family and enhance our understanding of evolutionary trend of helorid's metasomal structure, antenna, and fore-wing venation from the Middle Jurassic to extant.
