Superficially similar to species of Perigonia but immediately distinguishable by the unique forewing pattern.
Head and thorax with a medial dark brown line that extends onto the first two abdominal segments, where it branches to form a pair of subdorsal patches, between which is a patch of white scales; second to fifth abdominal segments pale pinkish-brown, the terminal segments dark brown, thus matching the extent of similar pattern elements on the forewings when the moth is at rest. Forewing upperside pattern unique among Sphingidae: a large chocolate-brown patch on the inner margin below the discal cell; apex of discal cell marked with a row of three small dots; pale pink-brown basal three-quarters of the wing separated from the darker brown apical quarter by a straight, diagonal postmedial line. Basal half of hindwing upperside pale yellow, distally merging gradually into a pale brown median band and then into a darker brown marginal band.
Male genitalia: Uncus formed of two apically rounded lobes.Gnathos formed of two apically pointed conical lobes.Valves thin, apically covered in numerous setae. Sacculus almost entirely separate from dorsal part of valve, joined at the base only. Harpes asymmetrical; both long, thin processes, the right longer than the left. Phallus dorsally with a strongly recurved apical hook bearing six very short setae and ventrally with a patch of needle-like cornuti.
