Abstract

The new cockroach specimens were collected from the third member of the Sinuiju Formation from Paektho-dong, Sinuiju City, North Phyongan Province, Democratic People’s Republic of Korea (DPRK). A new genus with a new species, Sinuijublatta sinuijuensa gen. et sp. nov., is described and assigned to the family Caloblattinidae. It differs from all the other representatives of the family by the sophisticated coloration (forewing with dark coloration except for pale areas in the R and M; hindwing with dark coloration in the distal half). These well preserved specimens were collected from the grey mudstones, the third member of the Sinuiju Formation. The new species broadens the distribution and the diversity of the family Caloblattinidae.
