摘要：

One new genus and two new species Ellca oblica sp. nov. and Kachinelcana elongata gen. et sp. nov. (Orthoptera: Elcanidae) are described and illustrated from the mid-Cretaceous Kachin amber. Ellca oblica sp. nov is the second species of the Kachin amber genus Ellca, and differs from Ellca nevelka by showing unique combination of forewing venation features, especially in the pterostigma. Kachinelcana elongata gen. et sp. nov is attributed to the Archelcaninae and differs from all other Elcanidae in a unique forewing venation. It represents the first definite fossil record of Archelcaninae in the mid-Cretaceous Kachin amber.
