Eupanacra sinuata (Taxonomy)
Transferred to Eupanacra by Cadiou & Holloway, 1989, Lambillionea89: 139. Erroneously returned to Panacra by Bridges, 1993, Cat. Fam. Gen. Spec. Sphingidae of the World: VIII.19. Returned to Eupanacra by Haruta, 1994, Tinea14 (suppl. 1): 156.
Forewing and hindwing outer margins slightly scalloped Forewing sinuate posterior to apex. Middle of thorax upperside and proximal abdominal tergites of similar pale colour to Eupanacra variolosa, a blackish brown stripe underneath the tegula continuing onto abdomen. Forewing upperside with five postmedian lines, first and second postmedian lines fused into a band ending at a spot on the costa, third, fourth and fifth postmedian lines narrow but well-marked, nearly straight as far as Rs4 before becoming faint and curving to the costa; fringe prominently dotted with blackish brown. Forewing underside with basal two-thirds drab brown; first postmedian line broad, ending at a small patch on the costa; a large brown submarginal patch extends proximad along M2 to the first postmedian line; a conspicuous blackish brown spot near tornus posterior to CuA2. Hindwing upperside with pale median band narrow, often just a line that does not reach costad of M3, not broader than the brown marginal band. Hindwing underside mostly drab brown; costal margin, inner margin and narrow submarginal band ochre speckled with brown; three distinct, somewhat dentate postmedian lines present, the first the heaviest. Uncus and gnathos similar to those of Eupanacra automedon. Valve strongly convex dorsally in distal half, with 4 or 5 large, asymmetrical, obliquely rounded-truncate stridulatory scales. Harpe ending in a stout process that is spatulate in dorsal view. Aedeagus with right lobe of apical process similar to Eupanacra automedon but narrower and less truncate; left lobe also broad, much more proximal, apex obliquely rounded, heavily dentate.
