Newton's parakeet, also known as the Rodrigues parakeet or Rodrigues ring-necked parakeet, is an extinct species of parrot that was endemic to the Mascarene island of Rodrigues in the western Indian Ocean. Several of its features diverged from related species, indicating long-term isolation on Rodrigues and subsequent adaptation. The rose-ringed parakeet of the same genus is a close relative and probable ancestor. Newton's parakeet may itself have been ancestral to the endemic parakeets of nearby Mauritius and Réunion.

This species has more legs than any other species of Peripatus; the females of the other species have at most 34 leg pairs, and the males have at most 32. The original description of P. evelinae was based on two specimens and reported females with 32 and 34 leg pairs, but another examination of these specimens revealed a male with 33 leg pairs and a female with 35 leg pairs instead as well as numerous embryos, including females with 35 and 36 leg pairs. The male specimen is 44 mm long; the female is 65 mm long. The type locality is in Goiás, Brazil.

The validity of this species is uncertain: Although some authorities deem P. lorentzi to be a junior synonym of P. papuensis, a similar species also found in Western New Guinea, others recognize them as two separate species.
