“I hadn’t seen anything like them before, and neither had Cornish spider expert Tylan Berry.
“So, strangely, this species has not been formally identified in its native range – so the only records in the world are on the Penryn Campus, and another recent record in Penzance.”
Mr Berry said it was “quite amazing that a new species to science has been found in the UK”.
He said: “This very rarely happens in modern times as the county is very well studied as far as spiders go.
“Who knew a pretty little 4mm jumping spider would be hiding in front of our eyes?”
