ABSTRACT

The unique Philippine spiny stick insect genus Stenobrimus, was reviewed. One new species, S. pilipinus Eusebio, Lit & Lucañas, sp. nov., is described from the forest over limestone outside the Cavinti Underground River and Cave Complex (CURCC) in Cavinti, Laguna Province. S. pilipinus, sp. nov., is unique among Stenobrimus species in having post-median mesonotal spines in both males and females. Its morphologically nearest congeners, S. bolivari Redtenbacher and S. tagalog Rehn & Rehn, are redescribed. The distribution of the genus in relation to karst forests and the historical biogeography of the Philippines is briefly discussed. Revised keys to the identification of Stenobrimus species for males, females, and eggs are presented.
