Parides neophilus, the spear-winged cattleheart, is a species of butterfly in the family Papilionidae.

Colombia to Paraguay and South Brazil, but not from Rio de Janeiro to Pernambuco, where P. zacynthus occurs.

— eurybates Gray (= euphales Gray) (5c), male with large white spots on the forewing; the red spots on the hindwing not blackish towards the base, with the exception of the first and last, the middle ones touching the cell on the under surface.

Sao Paulo and Matto Grosso; Paraguay (transition to the next form).

In the female the band of the hindwing is somewhat more curved than in the other subspecies; the narrow middle spots are placed close to the cell on both surfaces.
