Stumbled upon a drawing of the larva of Asioditomyia japonica (Ditomyiidae) which comes a bit close to your larve.
It is depicted as fig. 98 in Krivosheina, 2012. Howver, in her key on Palaearctic nematocera larva she writes on Ditomyiidae that Ditomyia and Asioditomyia has the penultimate segment dorsally with 2 long acute sclerotized projections, carrying spiracles, and this is a discriminating feature to separate the genera from Symmerus sp. So, does your larva has 1 or 2 spines on the penultimate segment?
