New species, new locality records and descriptions of calling songs of Phaneropterinae from Sabah

Based on recent sampling of orthopterans in Maliau Basin and Meligan (including near Long Pasia and Sinipung Hill), Sabah, Borneo, we present here notes on some of the katydids from the subfamily Phaneropterinae. Two new species were discovered and are described: Tapiena dimidia sp. nov. from Maliau Basin and Tapiena munae sp. nov. from Sinipung Hill near Long Pasia and Meligan. New locality records for Elbenia (Elbenia) paradigitata Gorochov, 2023, Stictophaula multa Gorochov & Voltshenkova, 2009, Holochlora falcata Tan, Liu & Ingrisch, 2024 and possibly Psyrana (Psyrana) nr. imitativa Gorochov, 2024.
