Individuals have prominent eyes and a short pair of palps on the head set between a further pair of long, bristly antennae of 30 or more segments.|
|Additional information||Petrobius maritimus, may be confused with Petrobius brevistylis which occurs in the same habitat. The two species can be separated by the sub-coxae of the male.
