Species text
This millipede is supposed to be a common inhabitant of old oak and mixed deciduous woods, sometimes quite acid, often in association with P. angustus, but not often recorded away from woodlands (Blower 1985). The 1988 preliminary national atlas records the species for S. Essex with a pre-1971 record for TQ89. The only relatively recent record for the county was by S.J. Gregory for Donyland Wood (TM015206) near Colchester in North Essex in 1991. Although there is seemingly plenty of suitable habitat in Essex, P.R. Harvey has never found the species and only identified it in material from two sites. References
