The genus Otraleus Günther, 1935 is recorded from the Philippines for the first time. Four new species, Otraleus bellemansae sp. nov., O. applai sp. nov., O. christianae sp. nov. and O. elizabethae sp. nov., are described from the highlands of Northwestern Luzon.

A new genus closely related to Otraleus, Capuyanus gen. nov., is described with a single species, C. magwilangi sp. nov., as type-species. An identification key and distribution maps are provided for all species.
