A New Species of Spinaeblattina Hinkelman, 2019 (Insecta, Blattaria, Mesoblattinidae) from the Lower Cretaceous of Paektho-Dong, Sinuiju, Democratic People's Republic of Korea

Spinaeblattinabaekthoensis sp. n. (Insecta, Blattaria, Mesoblattinidae), is recorded from the Third Member of the Sinuiju Formation from Paektho-dong, Sinuiju City, North Phyongan Province, Democratic People's Republic of Korea (DPRK). It differs from type species S. myanmarensis Hinkelman, 2019 from Cenomanian North Myanmar amber in breadthwise elliptical pronotum, without sharply curved posterior margin and the shape of dark markings in pronotum. Spinaeblattinayixianensis (Gao et al., 2018) from Barremian sediments of the Yixian Formation differs in forewing coloration and size. This well preserved specimen was collected from the grey mudstones and indicates that the genus extended to the DPRK in the Early Cretaceous and links its fauna with Yixian sediments and Myanmar amber.
