Owing to the flightless behaviour of the Pachyrhynchini, new species are still being discovered in unexplored parts of the region. Hence, we described a new species: Metapocyrtus bronsi sp. nov. discovered in Mount Hamiguitan Range Wildlife Sanctuary, Davao Oriental, Mindanao, Philippines. Habitat, ecology, and threats are also described.

Keywords: curculionid, Mount Hamiguitan, new species, terminalia, the Philippines

Metapocyrtus bronsi Patano & Yap sp. nov. 

Diagnosis. The new species differs from all known congeners by the presence of yellow gold to bronze scale markings with green to blue scales scattered at the edge of the markings in elytra and pronotum, and legs entirely black. Elytra oblongovate, coarsely striate-punctate similar with Metapocyrtus (Artapocyrtus) humeralis and M. (A.) humeralis aureofasciatus. Position of transverse bands in the elytra similar with M. (A.) humeralis and M. (A.) humeralis aureofasciatus but differs in the color of scales.

Etymology. The new species is named after the Mandaya word “bronsi” meaning bronze, the prominent color of the scale markings on the integument.
