A new species of Brachypremna Osten-Sacken,1887 from Dominican amber is described and illustrated,namely B.chenhuameii sp.nov..The new species is most similar to another fossil species documented in Dominican amber,B.brodzinskii Krzemi(n)ski,1996,by the wing patt,but is separated from the latter by the absence of final part of Sc,the arcuate origin of Rs,and the length of petiole of cell m1,which is distinctly longer than the cross vein m-m.A key to all fossil species of the genus Brachypremna is provided.
