The taxonomic study of the genus
Myzia
Mulsant, 1846 in Korea is presented. The genus
Myzia
contains five species worldwide and two species currently recognized in Palaearctic region. Until now, only
M. oblongoguttata
(
Linnaeus, 1758
) has been known in Korea, but we found
M. gebleri
(
Crotch, 1874
) for the first time in Korea. We redescribed these two Korean species of the genus
Myzia
with photographs of the habitus and detailed illustrations of their aedeagus and other appendages. A taxonomic key to the species of Korean
Myzia
beetles are also provided.
The world-widespread genus Myzia (Coccinellidae: Coccinellinae), was introduced by Mulsant (1846) with M. oblongoguttata (Linnaeus, 1758) as the type-species. They are medium sized lady bugs (with average length between 6.0 to 10.0 mm) with 2 spurs in each apex of middle and hind tibiae, clefted tarsal claws, and incomplete post-coxal lines (Gordon, 1985).The genus Myzia includes 2 species in the Palaearctic region, but only M. oblongoguttata has been reported in Korea. We added one more species, M. gebleri (Crotch, 1874), for the first time in Korea. These two species are described and figures of their habitus and aedeagus are provided.

All specimens of M. gebleri were captured by light trap in forest areas. According to the records of Japan, China, and Russia, this species has 2 types of body coloration: pale brownish surface with white to yellowish stripes; and blackish surface with white to yellowish stripes. Therefore, blackish M. gebleri might also exist in Korea.Distribution. Korea (new record), Japan, China, Russia, Mongolia, Morocco.
