[Syrphidae] Re: Querie: when to accept a species as new to the fauna?

[muscapaul]

We accepted a species of springtail as new for the Dutch list based on a
picture of an insect (was it a grashopper?) that accidentilly also captured
the springtail. For once, the springtail was unique in having a zebra
stripe pattern and thus even recognizable when it was slightly out if focus.
