Numbers
52 spp. in our area, ca. 450 described and ~1000 estimated spp. worldwide; ca. 35 spp. in Canada(1)
Identification
Antennae with 11 segments in both sexes. Both front and middle tibiae with two apical spurs. Large apical spur of front tibiae forked apically. Stigma usually large and semicircular, rarely absent or linear. Some are wingless/brachypterous. (2)
Wing venation similar and easy to confuse with similarly small aphelopine dryinids. Unlike the dryinids, megaspilid wings have only one (costal) vein and no long, narrow cell.
