Callambulyx rubricosa
Callambulyx rubricosa is very similar to Callambulyx amanda, but the hindwing upperside lacks a prominent black marking near the tornus.
Male genitalia: Uncus relatively weakly sclerotized, narrowing gradually towards apex; apex weakly emarginated; medial line raised as a carina; proximal part more strongly sclerotized and densely clothed with long hair-scales.Gnathos reduced, lacking a medial lobe. Valve narrow, tapering to rounded apex; harpe well developed, produced into a long and a short, curved pointed process. Phallus lacking armature.
Female genitalia: Lamella postvaginalis crescent-shaped, broadly rounded terminally; lamella antevaginalis approximately triangular.
The five specimens of Callambulyx rubricosa reported for South Korea by Park et al. (2006) are interpreted as either wind-blown or human-assisted strays.
