Abstract
Synopsis Four new species in the extant genera Austroconops Wirth & Lee and Leptoconops Skuse are described from Burmese amber: Austroconops asiaticus, Leptoconops burmiticus, L. myanmaricus and L. rossi. Johannsenomyia swinhoei Cockerell is redescribed and assigned to the extinct genus Atriculicoides Remm, which is treated as an indicator group characteristic of the Cretaceous period.
