As recently as the late nineteen century, Negros Island of the Philippines was still virgin forest. Unfortunately, due to combined effects of commercial logging, population growth and largescale agriculture, only 4% of the primary rainforest remained by the end of twentieth century. Here we report on the recovery of rainforest entomofauna. One new species of the genus Metapocyrtus Heller, 1912 from the Island of Negros, Western Visayas, the Philippines has been described, and one species known only from a type specimen, has been rediscovered after nearly one century. M. (Trachycyrtus) augustanae sp. n. was found in the Northern Negros National Park, along with the rediscovered M. (Orthocyrtus) bifoveatus, Schultze 1923. The species Eumacrocyrtus canlaonensis Shultze 1924. also has been collected on high elevation of the mount Canlaon and an addendum to its original description has been provided here. At the end we discuss similarity between monospecific genus Eumacrocyrtus Schultze 1924 and the species Orthocyrtus bifoveatus either as a synapomorphy which would require inclusion of the genus Eumacrocyrtus into the genus Metapocyrtus and the subgenus Orthocyrtus, or as mimicry between two species.
