A Primitive Sapygid Wasp in Burmese Amber (Hymenoptera: Sapygidae)
A primitive wasp of the family Sapygidae is described and figured from a male preserved in mid-Cretaceous (latest Albian, ca. 100 Ma) amber from Myanmar. The fossil is described as a new genus and species, Cretosapyga resinicola, and a new subfamily, Cretosapyginae, is proposed. The phylogenetic placement of the fossil is discussed. Cretosapyga is the oldest and first formally described fossil for the lineage, the only other record being a putative species of Sapyga (Sapyginae) in Baltic amber (Eocene: Lutetian, ca. 45 Ma).
