I do not think that any arthropods have a urinary system that excretes.

This is intriguing. I'm curious if this behaviour is known.
Remarkable photo. What initially struck me was it looks like one stream
comes from the center forehead, but this must be an illusion as the stream
is cut off or doesn't catch the light. The detail is not quite good enough
to tell. This unrelated photo linked below seems to show a pair of nozzles
below the ventral edge of the rostrum, and they might be forward-facing
