Gnathothlibus collardi is a moth of the family Sphingidae.

It is a hybrid between a female Philodila astyanor and a male Gnathothlibus eras.

The length of the forewings is about 35 millimetres (1.4 in).

Gnathothlibus collardi was described as a species, but by combining barcodes, morphology and a nuclear marker, research has shown that it is actually an F1 hybrid between two closely related species.
