Callionima falcifera
Forewing apex acutely pointed, falcate (although the degree is variable). Forewing upperside extremely similar to Callionima parce; consistently differing only in the pale oblique apical line expanding at M1 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.
Male genitalia: Uncus broad, sides divergent posteriorly in ventral view; with four pointed posterior lobes, the inner pair slightly shorter than the outer pair. Gnathos comprising two long, narrow, apically bluntly pointed processes, which are shorter than the uncus. Valves broader than in Callionima parce, apically more rounded. Harpe short, upcurved blunt pointed. Vesica with fewer small, spinose cornuti than Callionima parce.
