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 View Materials , specimen symbiocode_00899), SYC 1010-14 (= KX054269 View Materials , specimen symbiocode_01030), SYC2616-14 (= KX054271 View Materials , specimen symbiocode_02694), SYC2617-14 (= KX054270 View Materials , specimen symbiocode_02695), SYC2866-14 (= KX054268 View Materials , specimen symbiocode_02945), SYC4668-14 (= KX054274 View Materials , specimen symbiocode_04748), SYC5085-14 (= KX054272 View Materials , specimen symbiocode_ 05168), SYC5392-14 (= KX054266 View Materials , specimen symbiocode_05477) and SYC5393-14 (= KX054273 View Materials , 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).
