Callionima inuus
Most similar to Callionima parce and Callionima falcifera but distinguishable by the forewing having a straighter outer margin leading to an acute but not falcate apex and the straight (not curved) pale narrow line running inward from the apex. Forewing outer margin only slightly convex; apex acute, not falcate. Forewing upperside with straight pale apical line running inward from the apex to M2, here much nearer the patch of pale brown lunules than the outer margin.
Male genitalia: Uncus flattened, divided into four lobes, the medial ones long and slender, the lateral ones triangular and short. Gnathos with two slender processes that are curved inwards towards each other. Harpe ending in a slender, curved, obtuse process.Valve with spines at ventral edge near the harpe. Phallus without external armature.
