New data on the bush-cricket Montana medvedevi (Orthoptera: Tettigoniidae), critically endangered in Europe (EU 28), and a comparison of its song with all known song patterns within the genus Author Ivković, Slobodan Author Iorgu, Ștefan Author Horvat, Laslo Author Chobanov, Dragan Author Korsunovskaya, Olga Author Heller, Klaus-Gerhard text Zootaxa 2017 4263 3 527 542 journal article 33072 10.11646/zootaxa.4263.3.5 594bb190-aacd-4326-b9ad-01a5c3123366 1175-5326 573657 FF8FC6FD-0BE0-43EB-A5C4-881A4C70D792 Montana macedonica (Berland & Chopard, 1922) — Fig. 8 C. Localities : Bulgaria , Rila Mts , above Bistritsa Vill., 1150–1300 m ( N 42°05' , E 23°13' ), 27.vii.2016 , leg. D. Chobanov . Republic of Macedonia , Cer southeastern of Kičevo ( N 41°25' , E 21°03' ), 9.viii.1981 ( Heller 1988 ) . Republic of Macedonia , Titov Veles , Lake Mladost , 3.viii.1997 , leg. Fer Willemse . Serbia , Miratovac ( N 42°16' , E 21°38' ), 18.vii.2013 , leg. S. Ivković & L. Horvat . In the calling song, two types of verses are observed, short and long ones. The short verses start with a few (2–3) long syllables, called macrosyllables, which contain a series of impulses, and are followed by a short series of microsyllables (for details see Heller 1988 ). The long verses consist of a sequence of three-syllabic echemes. The first two syllables of each echeme are shorter and softer than the last one. Typically, a long verse follows immediately after a short one ( Fig. 8 C).
