I only saw/photographed one species of hoverfly in Ethiopia [Nov 15] and forgot about it until now. So I sent it off to Gerard Pennards, a re-known world expert on Hoverflies. He replied very quickly and identified the species as Phytomia incisa, a member of the Eristalini tribe. There are 30 species of Phytomia worldwide with 15 each in Africa and Asia. Phytomia incisa is found in eastern and southern Africa and regarded as a local species. I took multiple photos of both male and female specimens [ a couple below] and the World Syrphidae site [Syrphidae.com] were very pleased as they don't have photographs of this species. It was present at Bishangari Lodge woods on the southern bank of Lake Langano, Ethiopia.
