A tiny yuripopovinid true bug (Hemiptera, Pentatomomorpha) from Cenomanian Burmese amber

Abstract The true bug family Yuripopovinidae Azar et al., 2011 is documented in the Lower Cretaceous of northeastern China and Lebanon, and mid-Cretaceous Kachin amber of northern Myanmar. Up to now, two remarkable yuripopovinid genera and species with highly specialized morphologies have been reported in Kachin amber. Herein, its third species, Caulisoculus minutus sp. nov. in this amber biota is described and illustrated. The new taxon possesses a very small body size as well as a series of other novel morphological characteristics, which is distinctly different from the type species of Caulisoculus and other yuripopovinids as well, further providing us new insights to the disparity of the Cretaceous Yuripopovinidae.
