Yes, this is Syrphidae. I leave the more proper id for the pros.

Yes, a syrphid.
A female Eumerus sp., but it will be very difficult to get to species, it's a difficult genus, especially from Africa!

Females eyes are placed further apart. Males eyes almost touch each other in the middle.

There is a separate Syrphid Forum on this site.

The round abdomen and the yellow hairs around the scutellum are typical for E. feae. But there are several species in this group and only the males can be identified and only after the dissection of the genitalia... Nice fly and a great pic!
Cheers

I collected several specimens of Emerus feae-group this season in Thailand. Males Grin
In my fly scutellum is all dark, but antennae, on the contrary, yellow.
