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.
摘要在朝鲜平安北道新义州市白浦洞新义州组第3支蟑螂中发现了新的蜚蠊标本。报道了一新种Sinuijublatta sinuijuensa gen. et sp. nov.新属并归属于Caloblattinidae科。它与该家族的所有其他代表的不同之处在于其复杂的颜色(除了R和M的苍白区域外，前饰为深色;后翅在远端有深色)。这些保存完好的标本是在新义州组第三组的灰色泥岩中采集的。新种的发现扩大了小蠹科的分布和多样性。
