Synonym	Emoia oriva ZUG 2012
Distribution	Fiji Islands (Rotuma) Type locality: Fiji, Rotuma, 1.0–2.0 km south of Ropuri (12°29’S, 177°04’E).
Reproduction	oviparous (not imputed, fide Zimin et al. 2022)
Types	Holotype: USNM 268307, adult male, collected 22 May 1986 by G. R. Zug. Paratypes: USNM
Diagnosis	Diagnosis: Emoia oriva is a member of the Emoia samoensis species group and the samoensis subgroup (Zug et al. 2012). It differs from other subgroup members by a combination of traits. E. oriva females and males average smaller (mean 82 mm, range 75–85 mm SVL; 84 mm, 73–90 mm, respectively [Table 1]) than all other subgroup members, except equally sized E. tuitarere (female & male means 81mm&84mm):E.Tongansp(96mm & 97 mm), E. samoensis (97 mm & 100 mm), E. sanfordi (103 mm & 102 mm), and E. trossula type-series (90 mm & 91 mm). In scalation, E. oriva averages more dorsal scales [Dorsal] (median 70, 58–77) than other subgroup members: E. Tonga nsp (65, 58–72), E. samoensis (63.5, 60–68), E. sanfordi (58, 56–61), E. trossula type-series (65, 59–71), and E. tuitarere (64, 60–69); E. oriva usually has more scales around midbody [Midbody] (33–38) than E. Tonga nsp (30–36), E. samoensis (30–34), E. sanfordi (30–32), E. trossula type-series (31–36), and E. tuitarere (32–35); only E. sanfordi (47 & 66) exceeds E. oriva (38 & 56) in number of lamellae beneath the fourth digits of fore- and hindfeet (4FingLm & 4ToeLm, see Table 2), other subgroup members have fewer lamellae. Character abbreviations detailed in preceding Methods and Abbreviations section [from ZUG 2012].
Comment	Abundance: only known from its original description (Meiri et al. 2017).
Etymology	The specific name oriva derives from ‘oriva’, one of three Rotuman words for lizard. It is proposed as a noun in apposition.
