摘要
新种Punctatestheria yaojieensis Xue & Li sp.新种除了具有Punctatestheria特有的装饰特征--均匀分布的稀疏点状突起外，还在甲壳腹面或中部的生长线上有刚毛残留，点状突起呈线状排列在甲壳的后腹面。
New spinicaudatan species of Middle–Upper Jurassic Yaojie Formation from Lanzhou, Gansu, northwest of China
A new spinicaudatan species Punctatestheria yaojieensis Xue & Li sp. nov. is described from the Middle–Upper Jurassic Yaojie Formation at Yaojie in Lanzhou City, Gansu Province, China. In addition to the only evenly distributed sparse puncta, the special ornamentation of Punctatestheria, the new species has setal remains on the growth lines in the ventral or middle part of the carapace, and puncta are arranged in a linear manner in the postero-ventral part of the carapace.
