The common and widespread species of the North Island forests and shrublands. It lives predominantly in the litter and logs of the forest floor whereas C, sedilloti is under the bark and within treefern frond stems. Its size and distinctive square short wing covers that meet in the midline of the body makes for easy recognition. Its northern populations are slightly different and are perhaps intermediate between the main population south of Whangarei and the population on the Three Kings Islands. These may represent separate species, but there are few specimens from the far north to study.
