Dear forum people,

In 2012 I did an internship in a peat-swamp forest in Central Kalimantan, Indonesian Borneo. On Oct 4th 2012 I found this syrphid fly which I believe is a Ceriana species, based on some online searching. Could anyone please confirm this and (hopefully) is there any more classification possible to species level?
I only have this one picture. I reckon the fly is mimicking wasps of the subfamily Stenogastrinae, which were also occurring in the area.

Thanks in advance.
Stijn.
