Explanation of Names
Callionima falcifera (Gehlen, 1943) is listed as a stray by St Laurent (in Pohl & Nanz (eds.) 2023)(1) with Callionima parce of authors; (not Fabricius, 1775) as a synonym and true parce treated as extralimital north of Mexico.
It seems that a reliable characteristic is examining the apical area of the forewing. In Callionima falcifera, it seems that the area directly between the apical line and outer margin is the same color as the ground color of the wing, and not lighter. In Callionima parce, the area between the apical line and outer margin is lighter. (CATE)

The wings are also generally more falcate.
