Abstract

The Early Cretaceous genus Mesolygaeus Ping, 1928 is revised based on numerous specimens from the Lower Cretaceous Laiyang Formation in the Laiyang Basin, eastern Shandong Province, China. The genus Enicocoris Popov, 1980 is recognized as a junior synonym of Mesolygaeus syn. nov. and the family Mesolygaeidae, 1990 is therefore recognized as a junior synonym of Enicocoridae Popov, 1980 syn. nov. Also, the genus Longyanteclypea Zhang et al., 2013 is considered as a junior synonym of Mongolocoris Ryzhkova, 2012 syn. nov. Additionally, a new species, Mongolocoris polhemi Ryzhkova sp. nov., is described from the Lower Cretaceous Tsagaantsab Formation of Tsagaan-Suburga, Dornogovi Province, southeastern Mongolia.
