Taxonomy and bioacoustics of Meconematinae (Orthoptera: Tettigoniidae) from Laguna (Philippines: Luzon)

: Katydids from the subfamily Meconematinae sing at ultrasonic frequencies. Owing that many of them are nocturnal, elusive and low in abundance (since they are predatory), there is a dearth of information on these katydids and their bioacoustics, especially for species in the understudied yet mega-diverse Southeast Asia. Recent orthopteran surveys in Laguna, Luzon Island in the Philippines led to the discovery of two interesting Meconematinae katydids. Based on the collection, we describe a new species of Phisidini: Neophisis (Indophisis) montealegrei sp. nov. We also describe the male for the first time and redescribe the female of Asiophlugis philippina. The ultrasonic calling songs of both Meconematinae are also recorded, analysed and described here.
