ABSTRACT

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.

  • INTRODUCTION

    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.

    Redescription. Size: 6.0-7.0 mm in length, 4.5-5.0 mm in width.

    Coloration and shape: Short oval shaped, strongly convex; dorsal surface yellowish brown or reddish brown, finely punctate (Fig. 2A). Head reddish brown with a pair of white spots at inner ocular margin. Antennae and mouth parts reddish brown or brown. Pronotum with broad yellowish white parts at sides. Elytron with 3 white to yellow stripes and 1 spot near scutellum.

    Head: Head slightly transverse, narrower than half of pronotum. Frons densely and shallowly punctured. Mandibles with 2 teeth and distinct groove ventrally; lateral margin of mandibles with 2 long and 5 short setae (Fig. 2C). Antennae distinctly longer than head (Fig. 2D).

    Thorax: Pronotum narrower than two-thirds of body width; rounded at anterior and posterior corner; finely, but shallowly punctured. Elytra not distinctly shagreened irregularly punctured. Apex of middle and hind tibia and terminal tarsomere each with 2 spurs. Tarsal claw cleft (Fig. 2H).

    Abdomen: Abdominal ventrites pubescence sparsely. Post-coxal line incomplete (Fig. 2B). Female spermatheca hardly bended (Fig. 2G). Male tegmen relatively long and slender (Fig. 2F). Male sipho finely elongated (Fig. 2E). Posterior margin of last ventrites rounded in females (Fig. 2B), slightly caved in males.

    Remarks. 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.
