A new Pachyrhynchini species, Metapocyrtus (Artapocyrtus) colonnellii sp. nov., is described from the north of Catanduanes Island in the Bicol region of Luzon in the Philippines. This new species is similar to M. (A.) sexmaculatus Schultze, 1917 occurring allopatrically in the south of the island, but is easily distinguishable from the latter mainly by differences in scaly markings and endophallic structures.
