A new species, Orientogeochus antonkozlovi Legalov, sp. nov. from eastern Luzon, Isabela Prov. is described and illustrated. The new species is closely related to Orientogeochus rheinheimeri Legalov, 2021, but differs in having wider elytral interstriae, a longer rostrum, and elytra more constricted towards the apex. It is the second record of this genus from the Philippines.
