At the beginning of October I collected a large larva and now it is an adult:

The larva itself (about 25-28 mm).

Cerotelion, I'd say. Need to dig into the papers to see if there is more, but don't have time to do that now.

May I submit this to gallery? Or maybe You have time to check this one? According to this key to New Zealand fauna Cerotelion has one visible palpal segment, the other genera more. Here's only a stub of Palpus, so I guess it must be Cerotelion.

I cannot be certain based on these images alone.

According to the key to Keroplatinae genera in Zaitzev (1994), Cerotelion can be distinguished from Rocetelion by length of basitarsus I/tibia I ratio; it's 1.3 in C. lineatus and ca. 2 in R. humerale; we can't see the forelegs clearly yet median dark spot on wing is absent in R. humerale so I think it's C. lineatus.

Now it is just the question if Cerotelion and Recotelion were the only options... ;)

Hi, as far as I can tell in the key of Manual of Palaearctic Diptera the only close genera are from Japan, so I think yes. May I submit it to gallery as Cerotelion?

PS: C. striatum in FaunaEuropaea

I'd rather see the specimen before commiting myself. :D

I'd support Cerotelion striatum (= lineatum). In second European species C.racowitzai 1st basitarsus should be equal to 1st tibia (according to abovemetioned Zaitzev). Still I'm not sure if this character is safe to use. Zaitzev himself uses only male genitalia characters in his key. So Cerotelion sp. should be OK.

Perhaps belated, but having checked the different papers I can confirm AlexP is correct. You can submit pictures, if you want. ;)
