Callionima falcifera
Callionima falcifera is a moth of the family Sphingidae first described by Bruno Gehlen in 1943. It is known from Mexico, Belize, Nicaragua, Costa Rica and Jamaica, south through northern South America (north-western and eastern Venezuela).

Description 
The wingspan is 68–73 mm. The forewing apex is acutely pointed and falcate (sickle shaped). The forewing upperside is extremely similar to Callionima parce, consistently differing only in the pale oblique apical line expanding into a pale patch that does not curve back up the outer edge of the apical line towards the apex but is directed posteriorly towards the outer margin, resulting in the area between the outer margin and the apical line being the same colour as the area immediately basal to the apical line.

Biology 
The larvae feed on Stemmadenia obovata and probably other Apocynaceae species.
