A new record of Scytinopteridae from the Middle Triassic Tongchuan entomofauna of China

A new species of the extinct hemipteran family Scytinopteridae, Scytinoptera minusculata sp. nov., is described and illustrated based on a forewing specimen from the Middle to Upper Triassic Yanchang Formation of Tongchuan, northern China. The new fossil differs from Scytinoptera tongchuanensis by its extremely short common stem MP+CuA, strongly curved R vein, and distinct colour pattern. This finding represents the third record of Scytinopteridae in the Tongchuan entomofauna, enhancing the species richness of cicadomorphan insects in the fauna. Additionally, the diagnosis of Scytinoptera tongchuanensis is emended, with a supplemental description provided based on seven new specimens from the same locality of the Yanchang Formation as S. minusculata.
