چکیده انگلیسی
A new fossil praeaulacid wasp, Habraulacus zhaoigen. et sp. nov., is described and figured from Upper Cretaceous Myanmar amber. The new genus is established based on the following characters: mesosoma stout, metasoma elongated ellipse with the first metasomal segment very thin and tubular (like a petiole), forewing with pterostigma long and narrow, and both veins Rs+M and 1m-cu very long, forming a long cell 1mcu. Species of Praeaulacidae demonstrate a distinct evolutionary trend, which consists of miniaturization, venational reduction and enlargement of pterostigma, and reduction of number of the antennal segments from the Jurassic to Cretaceous. However, except for the miniaturization, this hardly concerns Habraulacus.
