Two new species of Dirhagini are described from Cretaceous Myanmar amber: Cenomana grandis sp. nov. and Protomicrorhagus latus sp. nov. Based on the new specimen, the diagnosis of the genus Protomicrorhagus Muona, 2020 is revised, and Protomicrorhagus brevis Muona, 2020 is re-described. An identification key to all Dirhagini species from Myanmar amber is provided. Prothoracic structures of Cretaceous and modern Dirhagini species are discussed.
