Ivković, Slobodan, Online, Published & Version, Final, 2017, First results of a faunistic survey on the Orthoptera of Jadovnik Mountain, southwestern Serbia, with data on the calling songs of some bush cricket species, Turkish Journal of Zoology 41 (6), pp. 1083-1095 : 1090

31. Psorodonotus macedonicus Ramme, 1931: 2 ♂♂, 1♀, Sopotnica Waterfalls (4), 10.07.2015; 10♂♂, 4♀♀, Sopotnica (forest meadow) (5), 18.07.2016 ; 6♂♂, 2♀♀, Vodice (roadside) (10), 18.07.2016 ; 5♂♂, Mali Jadovnik (roadside) (16), 19.07.2016 .

ECOLOGY: Pratinicole; terricole–graminicole.

Remarks: This species was previously recorded on 3 mountains in southern Serbia (Ebner, 1924; Us, 1938; Ramme, 1951; Matvejev, 1965). Jadovnik Mountain represents the northernmost locality of its distribution. Kaya et al. (2015) mention that boundaries with the ranges of 2 other Balkan species are not clear and so it is necessary to investigate the distribution of this genus in southwestern Serbia. Song consists of isolated syllables followed by 1–2 isolated impulses ( Figures 13A and 13B ).

Stridulatory file has 91 teeth ( Figure 14 ), fewer than reported in Kaya et al. (2015).

Pachytrachis Uvarov, 1940
