New species in the genera Eumacrocyrtus Schultze, 1923 and Enoplocyrtus Yoshitake, 2017 from Luzon Island, Philippines (Coleoptera, Curculionidae, Entiminae, Pachyrhynchini).

We describe and illustrate two new species from two previously monotypic genera Eumacrocyrtus Schultze, 1923 and Enoplocyrtus Yoshitake, 2017 from Luzon Island, Philippines: Eumacrocyrtusrobertfoxi sp. nov. , and Enoplocyrtusangelalcalai sp. nov. Eumacrocyrtusrobertfoxi sp. nov. serves as a new record for Luzon Island for Eumacrocyrtus which was only previously represented by E.canlaonensis Schultze, 1923 from Negros Island whereas Enoplocyrtusangelalcalai sp. nov. serves as an additional record of Enoplocyrtus in Mountain Province in Luzon Island. The discovery of these two new species from the Zoological Collections of the Philippine National Museum, collected in 1947 and 1985, respectively, highlights the value of natural history collections for the present and future generations of researchers.
