Abstract
Eminespina burma gen. et sp. nov., is described and illustrated based on a female embedded in Cretaceous Burmese amber of Cenomanian age. Autapomorphic are three unique spines distributed anterior quarter of pronotum from longer posterior part. The new evidence of Batesian mimicry in the insect fossil record is briefly discussed.
