A key, an annotated checklist with detailed distribution, biological and host information, and color photographic plates are provided for the 91 species of dacine fruit flies (Diptera: Tephritidae: Dacini) known to occur in Oceania. Dacus virgatus Coquillett, previously a synonym of Bactrocera psidii (Froggatt), is in­stead considered a junior synonym of B. facialis (Coquillett). The species originally described in 1971 as Dacus (Asiadacus) perpusillus Drew, later reassigned as Bactrocera (Sinodacus) perpusilla (Drew) and in re­cent years as Zeugodacus (Sinodacus) perpusillus (Drew) actually belongs to genus Dacus, and is transferred back to Dacus, but to the subgenus Neodacus, restored combination. The presence of B. redunca (Drew) is recorded for the first time in New Caledonia. New male lure records include isoeugenol and dihydroeugenol for both B. neoxanthodes Drew and Romig and B. quadrisetosa (Bezzi) and zingerone for Dacus taui (Drew and Romig), all in Vanuatu.
