I can’t see all the features used in the Gill key to heleomyzids (1)
but what I can see points to Suillia
as does the key in MND (2)
. The Gill key also points to this being S. quinquepunctata
but I’m not sure I can rule out S. longipennis
using this photo because it doesn't show the gena. I was not able to get any photos from other angles.
Some help with the ID would be much appreciated. TIA.
