Sthulapada Narendran, 1989: 145. Type-species: Sthulapada padata Narendran, 1989, by monotypy.

Diagnosis.

This genus comes near Thresiaella Narendran, 1989, in the key to genera of Chalcididae by Narendran (1989), but differs from it in having: 1) apex of hind tibia and hind tarsus swollen (in Thresiaella hind tibia and hind tarsus not swollen), and 2) ovipositor sheath with a tooth at apex (in Thresiaella ovipositor sheath without tooth). Sthulapada also comes near Oxycoryphe in general appearance, but differs from it in having peculiarly developed hind tarsal segments and ovipositor sheath with a tooth at apex.

Description.

Host.

Unknown.
