ABSTRACT: The subfamily Conganteoninae Olmi, 1984 belonging to the family Dryinidae is reported for the first time in South Korea based on the discovery of Conganteon nepalense Olmi, 1984 and Fiorianteon junonium Olmi, 1984. A key, diagnosis, illustrations and photographs of the diagnostic characteristics are provided.

The Conganteoninae Olmi, 1984, a small subfamily within the family Dryinidae, consists of fifteen species distributed in two genera (Xu et al., 2013): Conganteon Benoit, 1951 (11 species); Fiorianteon Olmi, 1984 (4 species). In East Asia, two genera and five species are recorded in China, one genus and species in Japan (Xu et al., 2013).
During our studies on Dryinidae, both above of the genera of Conganteoninae and two species, Conganteon nepalense Olmi, 1984 and Fiorianteon junonium Olmi, 1984, were identified for the first time in South Korea. This discovery gave the chance to provide a key to genera of Conganteoninae, diagnoses, illustrations and photographs of the diagnostic
characteristics.
Materials and Methods
All specimens are deposited in the Yeungnam University (YNU), Gyeongsan, South Korea. The terminology used in the present study follows that of Olmi (1984, 1994, 1999). The following abbreviations are used: OL, distance between the inner edges of a lateral ocellus and the median ocellus; OOL, distance from the outer edge of a lateral ocellus to the compound eye; OPL, distance from the posterior edge of a lateral ocellus to the occipital carina; POL, distance between the inner edges of two lateral ocelli; st, subapical tooth; TL, distance from the posterior edge of an eye to the occipital carina; MT, Malaise trap.
