Abstract

Two new genera and two new species of the lacewing family Hemerobiidae, Mischemerobia yumini Chen, Zhuo & Liu gen. et sp. nov. and Pararchaeomegaloma suzheni Chen, Zhuo & Liu gen. et sp. nov., are described from the mid-Cretaceous Kachin amber in northern Myanmar. Mischemerobia Chen, Zhuo & Liu gen. nov. differs from the other genera by the complex configuration of forewing recurrent humeral veinlet, the presence of two forewing ORBs, and the forewing MP distally fused with CuA. Pararchaeomegaloma Chen, Zhuo & Liu gen. nov. can be distinguished from the other genera by the presence of only one forewing ORB, with posterior most branch deeply forked, and the forewing MP forked near wing margin. Our finding provides new evidence for understanding the Cretaceous diversity and early diversification of brown lacewings.
