Hi,

Not sure if it is a Syrphid though..
The pictures were taken from a distance and cropped a lot, so not the best quality but maybe enough for id..

Paraty- Brazil, rainforest area, close to a river 23rd January 2010

Thank you for your help!

Yes, a syrphid indeed, a female Meromacrus sp. Maybe I can dig up the species, but I'll have to get back to it later.

Ah yes, from what I can find it's a female Meromacrus loewii!

Hi,
It's a Meromacrus, but I disagree with Gerard's species identification. M. loewi is a Central American species, as far as I know not known from Brazil. Besides, that species has submedial spots of yellow tomentum at the anterior margin of the mesonotum, as well as much more pronounced transverse fasciae on the tergites.
In my opinion, this specimen belongs to M. brunneus. I compared it with my Surinam specimens of that species (which were compared with the holotype) and they agree very well.

Hey Menno, thanks for the correction. That happens when one uses a key for the Costa Rican species of Meromacrus. The species you mention does not occur there, so I ended up with loewii.
