Ectatoderus sp. 2

Figs 157, 158

Diagnostic notes.

A yet unidentified species of Ectatoderus emits a calling song, as depicted in Fig. 157. That specimen has been collected, but was unavailable for analysis at the time of preparation of this paper. At the same collecting event on the same site, a second specimen was collected, depicted in Fig. 154 C. We assume both belong to the same species. A probable third specimen of this species is depicted in Fig. 158.

For characteristics, see Ectatoderus guichardi and Figs 154 C, 158.

Distribution and occurrence.

E. sp. 2 is known from Adho Dimello in the Hagher, where fair numbers were heard singing at night in 2010. Its song has also been recorded at Neet in 2010.

Bioacoustics.

Ectatoderus sp. 2 emits its calling song at night. It consists of two syllables with an interval of about 100–140 ms. This set of two syllables is repeated in a short series every 1–1.5s. The syllable duration is about 30–60 ms. The carrier frequency of the song is between 3.9 and 4.2 kHz, with some harmonics at higher frequencies (Fig. 157; XC 877954, accessible at https://www.xeno-canto.org/877954).
