Diagnosis.

This genus resembles Sthulapada Narendran in having an external extra carina on the hind tibia and a median tubercle on the pronotum. However, it differs from Sthulapada in having normal hind tarsal segments (in Sthulapada the hind tarsal segments (especially distal one) are unusually and greatly swollen) and the ovipositor sheath without a tooth (in Sthulapada ovipositor sheath with a tooth ventrally).

Description.

Pronotal collar in middle with a short median keel or tooth or a raised triangle (rarely weakly developed but distinctly indicated); apex of scutellum in most species distinctly produced posteriorly, ending in a lobe (in a few species emarginate); hind tibia with an additional external carina; mesosoma quite flat in some species; epipygium in typical form reaches near subapical part of ovipositor sheath whereas in some other species not at all reaching apex.

Hosts.

Parasitoids of Lepidoptera .

Distribution.

Africa (South Africa, Uganda) and Asia (India, Philippines, Malaysia, Singapore, Indonesia (Sumatra, Kalimantan), China (Taiwan) ( Narendran 1989; Noyes 2011), Vietnam (new record).
