Geographical distribution Pantropical: from southern USA south to Argentina , including the West Indies, introduced in the Afrotropical (including Madagascar , Mauritius , Reunion and Seychelles ), Oriental and Australasian Regions, and Oceania. Status in French Polynesia Introduced; recorded from Marquesas Islands , Gambier Islands , Austral Islands and Society Islands . Flowers visited Ornidia obesa has been observed visiting two plant species, belonging to two families: Citharexylum spinosum L. ( Verbenaceae ) and Rauvolfia sachetiae Fosberg (Apocynaceae) , the latter being endemic to French Polynesia . Genetics The BOLD Process IDs for the DNA barcodes (5′– COI ) for this species are: SYC881-14 (= KX054267 , specimen symbiocode_00899), SYC 1010-14 (= KX054269 , specimen symbiocode_01030), SYC2616-14 (= KX054271 , specimen symbiocode_02694), SYC2617-14 (= KX054270 , specimen symbiocode_02695), SYC2866-14 (= KX054268 , specimen symbiocode_02945), SYC4668-14 (= KX054274 , specimen symbiocode_04748), SYC5085-14 (= KX054272 , specimen symbiocode_ 05168), SYC5392-14 (= KX054266 , specimen symbiocode_05477) and SYC5393-14 (= KX054273 , specimen symbiocode_05478).The Barcode Index Number( BIN )for these specimens is BOLD:AAZ6930 (https://doi.org/10.5883/BOLD:AAZ6930).

Remarks Thompson (2013) listed Musca vespasianus Curtiss, 1938 as a synonym of O. obesa . From the original publication, there is no doubt that the synonym of O. obesa is Musca nero and not M. vespasianus , which is smaller, has spotless wings and black and white legs. This is merely an error in Thompson (2013) .
