Abstract

The early evolutionary history of the Macrocerinae subfamily (Diptera: Keroplatidae) is poorly understood. However, new material from the Cretaceous, particularly in amber, provides a better understanding of this subject. We reassign the oldest known species of Macrocerinae, Blagoderov & Arillo, 2002, from the amber of à lava (~105 Mya), to the genus ( comb. nov.). Furthermore, we reassess the systematic position of the problematic genus Cockerell, 1917 from Cenomanian Burmese amber (~99 Mya), providing evidence that it should be classified within this subfamily. Most significantly, we describe five new species from Burmese amber, including a new genus, PeÅ‚czyÅ„ska & SoszyÅ„ska, gen. nov., with two new species ( PeÅ‚czyÅ„ska & SoszyÅ„ska, gen. et sp. nov. and PeÅ‚czyÅ„ska & SoszyÅ„ska, gen. et. sp. nov.) and three new species ( PeÅ‚czyÅ„ska & Blagoderov, sp. nov., PeÅ‚czyÅ„ska & KrzemiÅ„ski, sp. nov. and PeÅ‚czyÅ„ska, sp. nov.).
