Stridulatory file: Starting from the wing base, the file is slightly curved and carries approximately 40 teeth, then suddenly the teeth (about 18 teeth) shrink and continue as a ladder-like structure downwards ( Fig. 15G View FIGURE 15 ). For details of morphology and measurements see Figs. 15G View FIGURE 15 , 18I –J View FIGURE 18 and Table 3.

Biacoustics: The faint male calling song is produced mainly in the evening and at night, consists of “click”- like syllables lasting about 7–9 ms, often separated by irregular intervals (between 1.4–7.8 s) ( Figs. 19–32). The impulse number of each syllable varies between 5–8. The first two impulses are generally crescendo type while the next impulses are decrescendo ( Fig. 37 View FIGURE 37 ). The syllable number per minute varied between 15–34 ( Fig. 20).

Coloration: See in Fig. 26A –B View FIGURE26 .

Remarks: P. vodnensis   shares the taxonomic characters of the P. zonatus   species group, and is the only member which can be found in the Balkans. This species is closely related to P. zonatus zonatus   , P. z. datca   ssp. n., P. variicercis   , P. varicornis   and P. salmani   sp. n., but differs from these species by having a wider fastigium, different shape of stridulatory organ, cerci and cercal apex in male, and different shape of pronotal disc in both sexes. P. vodnensis   shares similar characters with P. variicercis   , P. varicornis   and P. salmani   sp. n. by having distinct concave structure of the pronotal caudal margin. The calling song is also similar to that of the other members of the studied zonatus   group excluding P. tauricola   and P. azizsancar   sp. n.. The male song may be distinguished by its general pattern, less impulse number and shorter duration of syllables.

A male in July 1954 and a male and a female in August 1957 were initially discovered by Mladen Karaman in the Republic of Macedonia, on Mount Vodno at 900 m altitude, in an area with Rubus sp. ( Karaman 1958). Many subsequent researches in this area were carried out without any results. It is likely that anthropogenic changes of this mountain located on the outskirts of Skopje contributed to its rarefaction.

The species was found recently, but in the south of the country, near Prilep, in two different localities at less than ten kilometres from each other ( Lemonnier-Darcemont & Darcemont 2016):

1. Pass above Štavica: 41°15'04.3" / 021°35'20.9" at 1147 m a.s.l. Meadow with some thorn bushes including Rosa sp., in edge of beech groves. Nearly twenty taxa were also recorded including Bradyporus dasypus, Pholidoptera   macedonica, Montana macedonica, Poecilimon ornatus   , Metrioptera tsirojanni, Celes   variabilis, Stenobothrus fischeri, etc.

2. Between Dunje and Manastir villages: 41°13'04.0" / 021°41'24.6" at 590 m a.s.l. Grazed dry grassland on the edge of open oak forest (opened artificially). The population of Orthoptera   is diversified and rich, including the presence of Saga rammei   , S. natoliae   , B. dasypus   , P. ornatus, Arcyptera   microptera, Stenobothrus fischeri, etc.

These biotopes, which have in common the proximity of deciduous forests, are located on the collinean level. It should be also noted that the individuals have always been observed in areas where the herbaceous layer was the densest and the highest.

The period of occurrence of adults is between the end of May and the end of June, but as Karaman's observations showed, some adults could still be visible until July –August in Vodno Mountain. In the area of Prilep, we have never found adults so late which seems logical given the much more xerothermophilic character of these two localities.

This species is in “Near Threatened” status in the IUCN Red List of Threatened Species (2017–3) and in the European Red List of Orthoptera ( Hochkirch et al. 2016)   .

Breeding notes (2017): for the majority of individuals collected on May 20 at the Stavica locality (1150 m), the last moult occurred between the 28th of May and the 2nd of June. Two to three days later the males began to stridulate and the mating activities began. According to this first breeding experience, the sexual maturation seemed fast, and the survival rate after first mating for males or females was rather low, not exceeding one week.
