This is one of several large Lithobius with at least 4+4 forcipular teeth that can be confused with the common L. forficatus. L.piceus has a diagnostic spine 15VaC on the coxae of the last legs, and the last legs bear an ‘accessory claw’. Females have 3 or 4 gonopod spurs on each side (see images).
Distribution and Habitat
It is widely recorded from woodland in Surrey, Sussex and Hampshire, more recently also from a few woodlands in south Wales.
