Remarks.

Detailed morphological and acoustic descriptions, with rich illustrative material, were given by Karaman (1958) and Sevgili et al. (2018). Our song recordings of male-female duets provided in addition to the data by Sevgili et al. (2018), reveal two types of male song (either of single syllable or groups of two syllables) (Fig. 11 View Figure 11 ). The main, first, or single, syllable has 2–4 impulses (rarely up to 7) and lasts 5 to 16 ms. The second syllable was measured with 3 to 9 impulses and lasted 7 to 14 ms. Together the two-syllable groups had a duration of 34–82 ms. Male song of two syllable types is represented within the two subgroups of P. zonatus group and was reported for P. azizsancar and P. variicercis ( Sevgili et al. 2018) , as well as is common for the Poecilimon jonicus group (e. g., Borissov et al. 2020, 2023).

The female song consists of a first part of one or, more frequently, two impulses, and of a second part consisting of a few impulses with lower energy or a quiet ‘ buzz’ (compare Fig. 11 View Figure 11 – B and C). The first part of two impulses lasts 5–11 ms, while the whole song if the second part is present lasts ca. 40–60 ms. The latency times for the female response measured from the beginning of the male song was 27–39 ms (the latency lasts longer when there is one impulse in the first part of the female response). Table 3 View Table 3 provides additional characteristics of the species song.

Distribution.

This species is the only representative of the group in the Balkans, known only from the type locality, Vodno Mt., and a few closely situated locations in the Mariovo region of North Macedonia (Fig. 1 View Figure 1 , Table 1 View Table 1 , and Sevgili et al. (2018)).
