The Philippine Stick Insect genus Eubulides Stål, 1877 with the description of a new species from Mt. Apo Range, Mindanao Island (Phasmatodea: Heteropterygidae: Obrimini)

The Philippines is home to three species of Eubulides Stal, 1877 distributed in Imugan, Nueva Vizcaya and Polillo Island in Luzon. The first species under the genus, Eubulides alutaceus was described by Stal in 1877. The other two species, E. taylori and E. iggorote were described by Rehn & Rehn in 1939. This paper provides an updated and more detailed description and distribution of Eubulides species from the Philippines. A new and endemic species from Mt. Mahuson, Apo Range, North Cotabato is also hereby described and illustrated it represents the fourth species of the genus Eubulides Stal, 1877 from the Philippines and the first species of the genus to be described from Mindanao Island. The new species is distinct from the rest of the Eubulides species by the presence of a pair of spinose tubercles in the medial pronotals and postero-median tubercles in the abdominal tergites. The discovery of this new species from Mt. Mahuson provides additional data on the biodiversity in the area and can be used as a basis for proper forest management and policy-making to protect the area.
