Haplophilus subterraneus

Haplophilus subterraneus, commonly known as the western yellow centipede is a species of centipede in the family Himantariidae that can be found in Central Europe, Ireland, Newfoundland, Scandinavia and the United Kingdom. It was recorded from a compost heap of the Botanical Garden at the University of Oslo at Teryen, Oslo in 1992 and 1995.

It was for some time known as Stigmatogaster subterranea, but the name was reverted back to Haplophilus subterraneus in 2014.
