Two new genera and species are added to the fauna of dustywings (Coniopterygidae) preserved in Upper Cretaceous (earliest Cenomanian) amber of northern Myanmar, doubling the described diversity from this deposit. One genus is of the subfamily Aleuropteryginae and described as Achlyoconis heptatrichia Engel, new genus and species. This species is noteworthy for the infumate and patterned wings and unique presence of seven prominent setae positioned on thickenings occurring along the length of the forewing media. Paranimboa litotes Engel, new genus and species, is representative of the subfamily Coniopteryginae and distinctive among Mesozoic groups for the unbranched Rs, among other traits. In addition, a peculiar larva preserved alongside the holotype of P. litotes is described. While having a prothoracic and head form similar to aleuropterygines as well as a labial palpus with only two palpomeres, diagnostic for Coniopterygidae, the antenna bears four articles rather than the two present in crown-group dustywings. A revised key to the genera of Cretaceous Coniopterygidae is provided.
