Geographical distribution
South-central and central parts of the Pacific: Austral Islands over the Cook Islands, Marquesas Islands and Society Islands to the Hawaiian Islands (Lyneborg & Barkemeyer 2005).
Status in French Polynesia
Present; recorded from the Marquesas Islands, Society Islands, Austral Islands and Tuamotu Islands.
Flowers visited
Syritta oceanica has been seen visiting the flowers of three plant species in three families: Heliotropium foertherianum Diane & Hilger (Boraginaceae), Pemphis acidula J.R.Forst. & G.Forst. (Lythraceae) and Citharexylum spinosum L. (Verbenaceae).
Biology
See Terry (1910), although for Hawaiian specimens.
Genetics
The GenBank accession numbers for this species are: 28S gene (MF446469, specimen ZFMK-DIP-0019730), 18S gene (MF446424, specimen ZFMK-DIP-0019730), protein-coding COI gene (MF446519, specimen ZFMK-DIP-0019730). The BOLD Process IDs for the DNA barcodes (5′–COI) for this species are: SYC5088-14 (= KX054853, specimen symbiocode_05171) and SYC7899-14 (= KX054854, specimen symbiocode_08023). The Barcode Index Number (BIN) for these specimens is BOLD:ACN4472 (https://doi.org/10.5883/BOLD:ACN4472).

Remarks
We report here the first record of this species from the Tuamotu Islands. Lyneborg & Barkemeyer (2005) clarified the status of this species and the allopatric Syritta luteinervis de Meijere, 1908, and they explained the error of the New Zealand record for S. oceanica.
