13 to 19 mm - unicolourous black, or with slightly browner head and is very elongated with tapering elytra. Longitudinal rows of pits are obvious, as are densely scattered pits on the pronotum. The legs and antennae are black and the antennae are long, extending a way beyond the posterior margin of the pronotum, slightly shorter in the female.
Generally requires dissection to confirm the identification.
Best looked for where pine logs and stumps are present.
Spring and summer.
Thought to be associated with pine stumps.
Widespread and fairly frequent in Britain. The status has been revised since 2004, splitting this species from M. villosus, so precise status is unclear, but it would seem that M. castanipes is much the commoner of the two species.
Infrequent in Leicestershire and Rutland. There were only 4 VC55 records for this species up to March 2015.
