ABSTRACT

Ctenitis atrorubens Holttum, previously known only from the type collection made in 1905, was rediscovered through fieldwork in Central Mindanao, the Philippines. This rediscovery expands the species’ original distribution from Western Mindanao. A detailed and revised description of the species – including notes on its morphology, anatomy, and ecology – is provided.
