Diagnosis. This species is a typical large saturnid moth (wingspan 69–80 mm in males and 70–85 mm in females). Adult S. jonasii are characterized by a plumose antennae in males and a short pectinated antennae in females, irregularly purplish brown fore- and hindwings with different densities, often yellowish brown, which is more prominent in females; the large orbicular stigma on the eyespot on both wings, the ochreous and strongly slanted postmedial line and the brownish termen of forewing, the dark brownish transverse antemedial and medially strongly projected postmedial line, and the relatively wide subterminal band that shows a smooth interline and a strongly waved outer line of the hindwing. The S. jonasii wing pattern elements are very similar to those of S. boisduvalii but can be distinguished by the wider gap between the eyespot and postmedial line of the forewing and the smooth postmedial line and the dorsally strongly pointed outer line of the hindwing subterminal band. S. jonasii male genitalia are characterized by a bifid uncus, the long and strongly sclerotized chimney-shaped transtilla, the medially projected saccus, the triangular-shaped valva with a sharp apex, and the digitate harpe and rather thick aedeagus with one short and one long cornuti. S. jonasii male genitalia are similar to those of S. boisduvalii but can be distinguished by the sharply pointed apex and long button-shaped harpe of the valva and the two cornuti of the aedeagus. S. jonasii female genitalia can be distinguished by the semi-rounded and hairy papillae analis, the rectangular and strongly sclerotized ostium bursae, the medially narrowed ductus bursae, which are relatively short, and the anteriorly narrowed and membranous ovate corpus bursae that lack a signum. S. jonasii female genitalia are similar to those of S. boisduvalii but can be distinguished by the medially narrowed ductus bursae.

Hosts. Carpinus tschonoskii , in Betulaceae , Quercus phillyraeoides , Quercus serrate , Castanea crenata in Fagaceae , Lindera umberallata var. membranacea in Lauraceae , Prunus yedoensis , Prunus jamasakura in Rosaceae , Acer mono var. marmoratum in Aceraceae , Ilex rotunda in Aquifoliaceae , Swida macrophylla in Cornaseae, Lyonia ovalifolia in Ericaceae , and Styrax japonica in Styracaceae ( Shiromoto & Sakuratani, 2007) .

Distribution. Korea (Jejudo Island, new record), Japan, including Tsushima Island, and Taiwan.

Ecology. This species is univoltine during October in northern Japan (Sayama et al. 2012).
