Common Names 
SynonymPhaeoscincus ouinensis SADLIER, SHEA & BAUER in SADLIER et al. 2014 
DistributionNew Caledonia

Type locality: Mt Ouin, track along northeast edge of Mt Ouin Range, 22°00’S 166°28’E (elevation ~1000 m),  
TypesHolotype: MNHN-RA 2011.0276 (formerly AMS R.165819) collected by R.A. Sadlier and G.M. Shea, 27 December 2003 
DiagnosisDiagnosis: Phaeoscincus taomensis n. sp. can be distinguished from the only other member of the genus, Phaeoscincus ouinensis n. sp., in having two (vs single) lower secondary temporal scales, and significantly more lamellae beneath fourth finger (mean = 15 vs 12), scales on top of fourth toe (mean = 14.0 vs 11.5) and lamellae beneath fourth toe (mean = 29.5 vs 21.5).

Comparisons: The single adult female Phaeoscincus ouinensis n. sp. most closely resembles subadult and adult female Caledoniscincus austrocaledonicus from the southern region ultramafic ranges, and with which it is sympatric. It is readily distinguished from regionally sympatric populations of this species by differences in head scalation in having divided (vs fused) frontoparietal scales and fewer lamellae scales of the fourth digit of the pes (20-21 vs 23-28). It also resembles subadult and adult female Caledoniscincus notialis with which it is sympatric, and like this species lacks a noticeable mid-rostral streak. It can be distinguished from regionally sympatric C. notialis in having divided (vs fused) frontoparietal scales and fewer lamellae scales of the fourth digit of the manus (12 vs 14-19) and pes (20-21vs 26-35). 
CommentAbundance: only known from the type specimen (Meiri et al. 2017).
