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 : 1086

10. Poecilimon affinis dinaricus Ingrisch & Pavićević, 2010 ( Figure 5): 3♂♂, 1♀, Ogoreljača – Mali Jadovnik (meadow) (14), 12.07.2015 ; 3♂♂, 3♀♀, same locality, 20.07.2016 .

ECOLOGY: Pratinicole; herbicole–arbusticole.

Remarks: P. affinis dinaricus was found in moist forest meadow ( Figure 6 ).

In the first year of observation, only E. brachyptera was found together with this species, while in 2016 a large population of P. pseudornatus was also found together with P. affinis dinaricus , as well as a few M. brachyptera on the edge of the meadow. Specimens were found by their song, which they produced only during daytime, while males were singing day and night in captivity. Recorded song of 1 male (n 27, 20 ° C) consists of single syllables ( Figure 7A ) lasting 64–81 ms with intervals between them of 5–15 s. Songs of 2 males (n 8, 28 ° C) also consist of single syllables ( Figure 7B ) lasting 64–68 ms, with intervals between them of 5.5– 11.5 s.

Stridulatory file has 153 teeth ( Figure 4C ). This observation represents the second locality in Serbia for this species, as there were only 2 data in the literature that referred to Kamena Gora ( Ingrisch and Pavićević, 2010; Pavićević et al., 2014).
