[2] The species is native to North America,[3][4] where it can be found within the forests of California inhabiting crevices within coarse woody debris such as decaying logs and tree bark.

[5] The head of Bdellozonium cerviculatum features antennae that are about one and a half times longer than the width of the first body segment.

The clypeus is somewhat inflated in front of this depression, and the labral area gradually narrows, with a somewhat rounded apex.

The dorsal region of the body exhibits a moderately convex shape, with the posterior end being more abruptly rounded compared to the anterior portion.

The dorsal encroachment of the pleurae is minimal, forming a narrow raised lateral margin for each segment.

[5] Living specimens of Bdellozonium cerviculatum display a distinctive salmon pink coloration on the dorsum, which tends to appear more brownish when preserved in alcohol.
