Type species. – Pteromalus fulviventris Walker , designation by Ashmead (1904: 324).

Diagnosis. – Body metallic dark green; antennal insertions on the centre of face; antenna 12-segmented, apex of clava sharply acuminate or with a narrow spicula, females with the antennal formula 11263 (or 11353 in H. puchripes ). Clypeal margin truncate, slightly produced or with 2 teeth ( H. japonicus ); thoracic dorsum slightly convex; pronotum distinctly narrower than mesoscutum, notauli incomplete; propodeum with plica complete, median carina absent, nucha indistinct; stigma normal, shorter than postmarginal vein; hind tibia with 1 spur.
