Dioctriinae, probably Dioctria sp. ( I know very little about the Asilidae of Madagascar) I hope another expert can have a look at it. This specimen looks an awful lot like the Palearctic Dioctria longicornis.....

Thank you very much Quaedfiegh !!

It's a good information Smile

I will contact a expert on Afrotropical Asilidae, I think at Jason Londt.

Best regards,

Benoît

You are 100% sure that this specimen was collected on the island, it can't have been a mix-up?

This is very definitely Dioctria longicornis. Dioctriinae does not occur in the Afrotropics, and this fly is almost certainly not from Madagascar. If it is, it's an introduction.

Thank you Chris for the complementary information.

I'm surprised to know that species can be introduced in this region... The region is very isolated !

It's a interesting data.

Best regards,

Benoît
