Platygasteridae


 

Platygastridae: Platygastrids are minute (1.0-1.3 mm) shiny black wasps with reduced wing venation much like chalcids. The antennae have 10 segments, and are attached very low on the face, next to the clypeus.

  • Platygaster Latreille (fig. 65): Platygaster spp. ( 1 .3 mm) have clear wings without a fringe of hairs on the hind margin of the forewing, a trait which distinguishes them from Leptacis spp. (fig. 65). The scutellum is rounded off at the rear margin.

 

  • Leptacis Foerster (fig. 66): Leptacis spp. are similar to Platygaster spp., except for the somewhat dusky wings with a fringe of hairs. Length is 1.0 mm. They have a backward projecting spine on the scutellum.
