Abstract
In India, the cricket subfamily Eneopterinae is represented by two known genera, Xenogryllus Bolívar, 1890 and Indigryllus Robillard & Jaiswara, 2019. The latter was recently described and is known from a single species I. kudremu Robillard & Jaiswara, 2019 from Karnataka, India. The species was known exclusively from its morphological features and there existed no information on its biology and acoustic features. The present study is a step ahead in understanding the natural history and acoustic signalling in the genus. Based on a collaboration initiated by citizen science observations on the website iNaturalist, we describe a new species, Indigryllus sagani sp. nov. from Kerala, India, with details on its habitat and acoustic signals.
