Identification
Lithobius is a difficult genus and at least 17 species are known from Britain and Ireland.
Lithobius melanops is one of five 'smaller species' with 2 + 2 forcipular teeth that have backward projections on tergites 9, 11 and 13. This is the most common of the options. It is usually pale brown in colour, with an indistinct darker longitudinal dorsal stripe (to 17 mm body length).
Guidelines on how to distinguish the common Lithobius melanops from the much more restricted Lithobius tricuspis are given by Barber & Gregory (2019). Lithobius borealis also looks similar.
More information to allow accurate identification is given in the published identification keys by Tony Barber (2008 & 2009).
