DistributionCommon and broadly distributed in the Pacific, occurring from the Bismarcks through the Solomons and Vanuatu eastward to and including Polynesia; Society Islands,

Indonesia (Borneo)

Fiji Islands (widespread on all islands of a hectare or more, incl. Rotuma), Western Samoa, Admirality Islands, Toga, Loh, Tegua, Hiu Islands.

New Caledonia (Loyalty Islands), Vanuatu, Solomons, Papua New Guinea (New Britain), Tonga, Wallis, Niue, Tuvalu, Tokelau, Cook Islands, French Polynesia, Pitcairn Islands, Kiribati, Marshalls, Carolines, Marianas, Micronesia (e.g. Mortlock Islands, Chuuk), Nauru, Guam (one specimen only, G. Rodda, pers. comm., 13 March 2016).

USA (Hawaii)

Type locality: Tahiti.  
TypesLectotype: MNHN-RA 7069A (part 2762), O-Taïti (= Tahiti), collected by Lesson & Garnot, designation by Brygoo (1985). Paralectotypes: MNHN-RA 7068, MNHN-RA 7068A-B, MNHN-RA 7069, MNHN-RA 7069A ((7 syntypes). Note that according to some authors those syntypes were mixed and they do not correspond to the original description of E. cyanura.
Holotype: MNHN 1987.1301, male [Emoia pheonura]
Syntype: MCZ 6463 [arundelii] 
CommentDistribution: Does not occur on mainland New Guinea and New Caledonia (BAUER & VINDUM 1990). Reported from the Philippine Islands (e.g. Taylor 1922) but apparently not there yet.

Similar species: Ineich 2011 considers only two distinct morphotypes from Vanuatu from what was previously called E. cyanura, the brown tailed morph that he (provisionally) calls E. cyanura and the blue tailed morph that he (provisionally) calls E. impar. E. cyanura has a blue tail while pheonura has a brown or brown-green tail (according to INEICH 1987).

Lectotype: In 1986, Brygoo designated MNHN 7069A as the lectotype of E. cyanura but that decision cannot be accepted since the type series, having originated from Tahiti (French Polynesia), does not include blue tailed morph specimens such as the one illustrated on Lesson’s original iconotype plate published in 1826, but only brown tailed morph specimens and some specimens of E. caeruleocauda, a species not occurring in French Polynesia (see above). Thus in 1987 Ineich recommended con- sidering that type series as invalid and the syntypes of E. cyanura as having been lost (or mixed with other specimens in MNHN collections) [Ineich 2011].
