Treatment

Genus Isostasius Förster, 1856 View in CoL View at ENA

Isostasius Förster, 1856: 106 View in CoL , 109–110. Type species Platygaster punctiger Nees, 1834 by monotypy.

Remarks

Isostasius is remarkable in that the female metasoma has only three visible tergites. The genus was treated by Masner & Huggert (1989). The type species is Platygaster punctiger Nees, 1834 , and we consider the type material to be destroyed. There are seven males in the NHMW labeled as original exemplars, but these are not suitable for neotype designation. A female neotype would be more appropriate, due to the sex-specific metasomal structure.
