A new well-preserved spinicaudatan species named Yanjiestheria huajiyingensis sp. nov. is described from the Huajiying Formation in northern Hebei, northern China. This species is distinguished by the presence of transverse ridges in the postero-ventral part of the carapace. Preserved eggs in the new species provide insights into sexual dimorphism in Yanjiestheria.
