Abstract
The extinct family Yuripopovinidae Azar et al., 2011 was erected based on a true bug fossil in Lower Cretaceous amber of central Lebanon. Recently, a unique yuripopovinid Reticulatitergum hui Du et al. (2019), with an areolate body and strongly dilated antennal segment IV, was reported from mid-Cretaceous Kachin amber of northern Myanmar. Herein, the second yuripopovinid genus and species from this amber biota, Caulisoculus electrus gen. et sp. nov., is described and illustrated. The new taxon bears bizarre long eyestalks, which is an unusual morphological trait amongst true bugs. The two specialized yuripopovinid genera (Caulisoculus gen. nov. and Reticulatitergum) suggest that this extinct pentatomomorph lineage was with high disparity in Kachin amber biota.
