Distribution	Papua New Guinea (Owen Stanley range) Type locality: Mount Victoria, Papua New Guinea
Reproduction	oviparous
Types	Holotype: BMNH 1946.8.10.82 (formerly 96.10.31.6), Mt Victoria, Owen Stanley Range, New Guinea, collected A.S. Anthony.
Diagnosis	Diagnosis (genus): Medium-sized (adult SVL 36.3–67.8 mm) terrestrial skinks with short forelimbs (forelimbs 25.1– 38.9% of SVL) and moderately long hindlimbs (33.6– 49.6% of SVL); lobules present on anterior edge of ear opening; single pair of chin shields in medial contact; three supralabials posterior to subocular supralabial; chin shields abutting infralabials; lower eyelid with semi-transparent window; standard three-scale temporal region; nasal scale divided by a horizontal suture extending posteriorly from the nostril; frontoparietals fused; oviparous; clutch size two; pustulate egg shells. Papuascincus differs from all other genera by having pustulate egg shells and a divided (vs. undivided) nasal scale. It further differs from Nubeoscincus, Prasinohaema and Lobulia by having one pair of chin shields in medial contact (vs. two pairs) and an oviparous (vs. viviparous) reproductive mode. It further differs from Nubeoscincus and Prasinohaema by having the standard three-scale temporal region (vs. fragmented temporal region) and the chin shields abutting the infralabials (vs. chin shields separated from infralabials by a row of genials). It further differs from Prasinohaema by lacking green blood serum and tissues (Greer, 1974), a prehensile tail with a glandular tip and basally expanded subdigital lamellae (Slavenko et al. 2021).
Comment	Type species: Papuascincus stanleyanus is the type species of the genus Papuascincus ALLISON & GREER 1986. Phylogenetics: Slavenko et al. 2020 found high diversity within this monophyletic group. Type: not in BMNH (P. Campbell, pers. comm., 7 July 2014).
