New species of Clothodidae and Scelembiidae (Insecta: Embiodea) with diverse terminalia from Myanmar amber

Two new genera and three new species of webspinners, Electroclothoda aroliata gen. et sp. nov., Cretembia longimandibula gen. et sp. nov. and Parasorellembia grandiocula sp. nov., are described from the Upper Cretaceous of Myanmar amber. Electroclothoda aroliata gen. et sp. nov. is classified in the Clothodidae by having symmetrical male terminalia and an undivided tenth abdominal tergum. Cretembia longimandibula gen. et sp. nov. and Parasorellembia grandiocula sp. nov. are attributed to the Scelembiidae based on their distinctive terminalia: asymmetrical male terminalia, slender left cercus and robust, hook-shaped right cercus. Furthermore, a more detailed interpretation of terminalia architecture in Scelembiidae is provided.
