look to me like a Tabanidae larva, and as the anal segment is pretty short it is most likely a member of Haematopota, but not sure though. The fine longitudinal striae on the body is almost unique for tabanidae, but I know of one Muscidae species which has this too. But this isn't a Muscidae. Also I can see lateral (and ventral?) pseudopods here, which are also present in Tabanidae and less distinct in Rhagionidae. Rhagio larva has four small anal lobes and I can't see them here.
Did you collect it? and if so, can I have it?
