New beaded lacewings (Neuroptera: Berothidae) from the mid-Cretaceous of Myanmar with specialized cephalic structures
Abstract
Two new genera and five new spices of the lacewing family Berothidae from the mid-Cretaceous Burmese amber are described. Cornoberotha gen. nov. with three new species (C. anomala sp. nov., C. aspoeckae sp. nov., and C. monogona sp. nov.) and Dolichoberotha gen. nov. with two new species (D. burmana sp. nov. and D. bifurcata sp. nov.) are both closely related to Ansoberotha Yang, Shi & Ren, 2019 by having the strongly elongate antennae. Frontal horns are first found in Berothidae. The male genitalia in these "long antennae" berothids retain the separation of tergum 9 and ectoprocts and the absence of bristles on the gonocoxites 10 complex, which are plesiomorphic, while their female genitalia possess some apomorphic character states, such as the paired sternum 7 and the presence of hypocaudae, which are shared by the higher berothid subfamilies, e.g. Nosybinae and Berothinae. Accordingly, the presently described berothids probably represent the stem-group of higher groups of Berothidae.
