Callionima ramsdeni is a species of moth in the family Sphingidae which is known from Cuba.

[1] It is similar to Callionima parce and Callionima falcifera falcifera but smaller and with a blunter and less acuminate (pointed) forewing apex.

The forewing upperside has a patch of indistinct pale brown lunules, merged to form an amorphous patch.

There is a sharply marked narrow line extending inward from the apex passing through two conspicuous black spots.

The hindwing upperside has a single black band in the anal area, the area between this and the margin is pale.
