What type is this aircraft with "inverted" wings?
If I am not horribly mistaken, it seems to be an Antonov 72 or 74, that were produced together, hence the similarity.

Another image (not included for copyright reasons) can be found here.

The wikipedia article classifies it as a "transport aircraft". It mentions a VIP transport variant and a maritime patrol one for the An72, several more variants are listed for the An74 version.



EDIT:

Flightradar24 lists only one An72 in the possession of CAVOK Air (thanks to bjelleklang for identifying the livery), registration UR-CKC.

The historical data indicates that this aircraft landed in Tampa on the 24th of May after a stop in St. John's on its way from Reykjavik.






  It has an odd combination of a negative dihedral and pylonless overwing engines, all traits I've seen individually but not together.


Concerning the anhedral (the name of "negative dihedral") angle, you can find more info here, but we can summarize here that it has more to do with the high wing mount rather than the engine one.

The overwing mount of the engine contributes to reducing the risk of foreign object ingestion on unpaved runways.



Update:

The aircraft has been damaged beyond repair in a runway overrun accident occurred on Jul 29th 2017.
