Diagnostic notes.

A third species of Ectatoderus is only photographed and sound recorded. See Ectatoderus guichardi and Figs 159 View Figure 159 , 160 View Figure 160 for diagnostic characteristics.

Distribution and occurrence.

Ectatoderus sp. 3 is known from two photographic records by James Bailey in 2024, one at Firmihin and one on Noged Plain (Figs 159 View Figure 159 , 160 View Figure 160 ), both in two very different habitats. These records suggest a rather wide distribution on the island (see https://www.inaturalist.org/observations/203184039 and https://www.inaturalist.org/observations/199187230. E. sp. 3 probably also occurs at Neet.

Bioacoustics.

The calling song of Ectatoderus sp. 3 , emitted at night, resembles the song of E. sp. 2. in structure (Fig. 157 View Figure 157 ), but is higher (Fig. 161 View Figure 161 ). The carrier frequency of this taxon seems to vary between 5.0–5.9 kHz. The specimen depicted in Fig. 161 View Figure 161 has a carrier frequency of around 5.0 kHz. In the recording made at Neet, where the same type of song was recorded in 2010 (RecRF 10119, 125–127), the frequency is around 5.9 kHz.

Recordings at Neet also show a taxon with a frequency of 3.9 kHz, possibly belonging to Ectatoderus sp. 2 (RecRF 10129–141). Further analysis of the bioacoustics of both species can only be satisfactorily conducted if the specimens from which the recordings were made are available for study.
