Eupanacra busiris
Transferred to Eupanacra by Cadiou & Holloway, 1989, Lambillionea89: 139. Implicitly transferred to Panacra by Zhu & Wang, 1997, Fauna Sinica Insecta 11: 335 (key), 336. Implicitly transferred back to Eupanacra by Kitching & Cadiou, 2000, Hawkmoths of the world: 45.
The vivid green colour on the upperside of the head and thorax, and the characteristic green area on the forewing comprising a broad costal band with a lobe extending towards the hind margin should make this subspecies unmistakable. In the other subspecies of Eupanacra busiris the colouration is duller. Of the other species, only Eupanacra splendens shows a similar pattern, though much less well defined, but is readily separated by the broad orange band on the hindwing upperside. Distal margin of forewing deeply sinuate, the apex more produced than in other Eupanacra; the angle at vein M2 more acute in males than most females. Hindwing narrow, the costal margin clearly dilated near the base. Upperside of head and thorax green. Forewing upperside with space between antemedian and postmedian lines green, like upperside of head and thorax, contrasting with the rest of the wing. Uncus rather short and broad, not much longer than gnathos. Gnathos tapering. Valve with numerous small stridulatory scales. Harpe similar to Eupanacra regularis regularis in lateral view, but less curved. Aedeagus apical process with the two slender, dentate, approximately equally wide lobes, arising from a short common stem, left much longer than the right with the serrate apex oblique so as to face the exterior; right process acute.
