Thank you Tony and Tristram for the input and Nikita for the Genus. Read up on these that they are nigh on impossible from photos. I only have 3 species of Spilogona on the Checklist for Shetland [for what that's worth]! They are
Spilogona falleni, Spilogona surda, Spilogona trianguligera

Regards

Roger
