The specific name, gervaisii, is in honor of French zoologist Paul Gervais.

[3] Its range includes the islands of Basilan, Catanduanes, Cebu, Lubang, Luzon, Mindanao, Mindoro, Negros, Panay, Polillo, and Tablas.

[1] C. gervaisii is found from near sea level up to altitudes of 1,000 m (3,281 ft).

It lives in forests and plantations, burrowing in the leaf litter and hiding under stones and fallen logs, or between the buttresses of trees.

[4] The IUCN has listed C. gervaisii as being of "least concern" because it has a wide range, appears to be abundant with a stable population, and seems to be tolerant of disturbance to its natural habitat.
