The four-spined pygmy devil (Arulenus validispinus Stål, 1877) is an endemic species to the Philippines. It was described more than 140 years ago from a single female specimen. Since its description, only a single new record was known, reported by Skejo from the Lanao region in 2017 and based on a specimen from eBay. Here, we record the species from the Bukidnon Mountains. We present measurements of a male and a female we collected, with the description of the species morphology and habitat. This species differs from its congeneric Mia’s pygmy devil (A. miae Skejo & Caballero, 2016) by the sharp dorsal and lateral spines.
