The former Scelionidae (sensu stricto) is considered to be a part of Platygastridae, recently. During the parasitic wasp collecting with yellow pan trap, aiming at investigating promising biological control agents which attack on plantbug pests for soybean cultivation, one new species and one unrecorded scelionine species were identified.
Opisthacantha albertoi sp. n. was collected from central part of korean peninsula. It is very unique by its yellowish body, compared with the black of the most recorded korean scelonine species. It has a long ovipositor which is 1.3 times longer than body length. It was named after the late Dr. S.-B. Ahn, the noctuid specialist.
The unrecorded Tiphodytes gerriphagus (Marchal) was famous for its extremely extraordinary habit of diving for Hymenoptera to attack the eggs of gerrid hosts (Gerris, Trepobates spp.). It was collected nationwidely in Korea.
As a result, two genera are newly added in korean scelionine fauna and korean Scelioninae is composed of eight species in five genera in total.
