Protambulyx goeldii, Nicaragua, Olivier Digoit.

"P. astygonus is very similar in external appearance to P. goeldii. However, the two species can easily be distinguished by the presence of a prominent dark spot at the apex of the forewing discal cell in P. goeldii that is missing in P. astygonus."

The hindwing upperside of goeldii has a straighter distal edge and a less curved antemedian line. The median line is absent, and the submarginal line less dentate, compared to astygonus.

P. goeldii also has a more elongated, dark basal patch, emanating from the inner margin, compared to similar species.
