Callionima ramsdeni (Clark, 1920)

Similar to Callionima parce and Callionima falcifera but smaller and with a blunter and less acuminate forewing apex. Tegulae pale brown with a dark brown border, sharply tipped with white posteriorly (uniform dark brown in Callionima parce and Callionima falcifera). Forewing upperside with patch of pale brown lunules indistinct, merged together to form an amorphous patch; sharply marked narrow line extending inward from the apex passing through two conspicuous black spots, one between Rs₄ and M₁, the other between M₁ and M₂. Hindwing upperside with a single black band in the anal area, the area between this and the margin pale (in Callionima parce and Callionima falcifera, this area is darkened).
