ID Difficulty


Ten species of Geophilus are known from Britain and Ireland. 

Geophilus impressus is the species formerly known as Geophilus insculptus (as used by the identification keys of Barber, 2008 & 2009) and subsequently Geophilus alpinus.

It is yellowish-orange centipede (to 40 mm length) with distinct carpophagus fossae on the anterior sternites. The combination of 45 to 53 leg pairs and the presence of an 'isolated coxal pore' on the last leg pair is distinctive.

More information to allow accurate identification is given in the published identification keys by Tony Barber (2008 & 2009).
