Korsunovskaya, Olga, 2024, Drymadusini katydids (Orthoptera: Tettigoniidae; Tettigoniinae): intraspecific variability-morphs or subspecies?, Zootaxa 5403 (1), pp. 42-50 : 49

E. mongolicus

Male calling song was described earlier ( Korsunovskaya et al., 2002). Here we present additional oscillograms ( Fig. 3A, B ), frequency spectrum ( Fig. 3C ) of this sound signal and for the first time microphotographs of the stridulatory file ( Fig. 3G, H ) with 51 ( Fig. 3G ) and 54 ( Fig. 3H ) teeth.

FIGURE 3. Temporal pattern, frequency spectra of male calling songs and stridulatory files of E. mongolicus and L. miramae. A, B—oscillograms of calling song of E. mongolicus f. caeruleum; C—frequency spectrum of calling song of E. mongolicus f. caeruleum; D, E—oscillograms of calling song of L. miramae; F—frequency spectrum of calling song of L. miramae; G—stridulatory file of E. mongolicus (Mongolia); H—same of E. mongolicus f. caeruleum (Tuva); I—same of L. miramae (Uzbekistan). B, E—oscillograms at higher speed. Spectra are in linear scale. Scale bar: A, C—500 ms, B, D—50 ms; G—I— 500 µ. The temperature when recording sounds is given.
