Description A detailed description of Pteronemobius cf. arima is not included here, since I am not designating or describing a new species, nor would I know how to differentiate it from P. arima proper, assuming it is different at all. Images of the main characters are in Figs 8D , 25 and 27G–L. MEASUREMENTS . See Table 6 , also Figs 6–7 . No sexual dimorphism. SONG . A very quiet sequence of chirps, rather like a mere whisper, difficult to record. Peak frequency between 6 kHz and 7 kHz, each chirp approx. 0.2 seconds in length; interval between chirps between 0.4 and 0.7 seconds long. Pulse rate approx. 40 pulses per second. See also Fig. 26 and Table 6 . Habitat and ecology Pteronemobius cf. arima is a nocturnal species, more tolerant of dry conditions than P. truncatus . It inhabits a variety of grassland habitats, including swamp, rank grass, lawns and sports fields. Pteronemobius cf. arima often forms mixed populations with the larger Pteronembius truncatus and with ground crickets in the genus Bobilla , with which it could easily be confused.
