Chordeuma proximum - a new Millipede for Nottinghamshire
In early January 2015, we discovered an immediately different looking Millipede, to any which we had recorded before. It was found under an old piece of carpet, dumped along a former railway line, which used to access the Clipstone Colliery.

Underneath the same carpet, were singles of Blaniulus guttulatus and the compulsory Cylindroiulus punctatus, both Millipedes we find regularly.

Just its very habit, was enough to make us suspect that it was something different, so we took many photographs while on site, but took it home to try and get photographs of better quality and in better natural light.

Thankfully, photographs took at the time, plus those on return home, were enough to help us realise that this was indeed an interesting find and certainly a Millipede at least new to us. It measured approximately 13mm and the resulting photographs enabled us to key it out as a Chordeuma species, of which there are two in the UK.

Both Chordeuma sylvestre (C.L.Koch, 1847) and Chordeuma proximum (Ribaut, 1913) are known to have strong south-westerly distributions in the UK and are visually identical, but the most likely species based on its wider UK range alone would be Chordeuma proximum.

Later examination under the microscope, confirmed that our Millipede was indeed a male Chordeuma proximum and an obvious first record for Nottinghamshire, coming only a couple of weeks after we had published our Modern Atlas of Nottinghamshire Millipedes.

Recent UK records away from Wales and south-west England, would suggest that Chordeuma proximum is a more widespread Millipede than had been previously thought. Paul Richards very kindly provided us with some recent records and county firsts, taken from the Newsletters of the British Myriapod and Isopod Group (BMIG) which give details on C. proximum being recorded as new to Suffolk (and East Anglia) in June 2013 (Lee, P.), at several locations in North Yorkshire between May and November 2013. (Wardhaugh, T.) and near Kielder Water, Northumberland in April 2014 (Richards, P.).
