Potential effect of the global warming to the subfamily Lipotactinae (Orthoptera: Tettigoniidae) in China and acoustics data of Lipotactes truncatus Shi & Li, 2009

Species in subfamily Lipotactinae are brachypterous with a small body and have limited dispersal ability. In this study, it’s the first time to describe the male calling song of Lipotactes truncatus Shi & Li, 2009. MaxEnt was used to predict the potential geographic distribution of Lipotactinae in present-day and year 2070, to explore responses to global warming of this subfamily in China. As for L. truncatus, two types of calling songs are observed with peak frequencies in the ultrasound range. With the trend of global warming, the suitable habitats of subfamily Lipotactinae will change in three ways: i) migrate to high latitude area; ii) migrate to the coastal region of south China; iii) migrate along altitude gradients in mountains. Some species will be locked into the “sky islands”, which will accelerate speciation process, with global warming.
