摘要
Macaroblattula ellipsoides gen. et sp. nov., Elisanta cuboides sp. nov. and E. extenuata (Ren, 1995) of the dominant cockroach family Blattulidae are described from the Late Jurassic/Early Cretaceous Yixian Formation of western Liaoning in China. Forewing venation of E. extenuata reveals low variation (CV for total number of veins = 6.22), which indicates active flight of this advanced taxon. Presence of Macaroblattula gen. nov. suggests a generic variation and high adaptability of the family. Taxonomic composition supports the transitional Late Jurassic/Early Cretaceous age of the Yixian Formation and dominance of the family Blattulidae within assemblage indicates their significance in food chain.
