It was high pitched, hardly audible to humans and therefore we had to use ultrasonic detectors. Later we collected some specimens and found out that it is an undescribed species. Here we publish a description of this new taxon with the name Cicadivetta goumenissa sp. n. In addition to morphological characteristics this species is distinguished by a song pattern with very fast sequences of short echemes (SE, duration 26+_7 ms) of different duration (a few SE up to more than 500 and 37 s duration and repetition frequency of 13-22 SE/s), followed by single long echemes (LE, duration: 535+_88 ms). Exceptionally there are sequences with longer LE echemes (760+_284 ms) and without or just a few SE in-betweenNa Peloponezu pri kraju Goumenissa v Grčiji smo v letih 2005 in 2006 slišali in posneli nenavaden in neznan napev škržada. Pri tem smo uporabljali ultrazvočne detektorje, saj je frekvenčno območje teh signalov na zgornji meji človeku slišnega območja. Kasneje smo nekaj teh majhnih škržadov tudi ujeli in ugotovili, da gre za novo, še neopisano vrsto. To novo vrsto imenujemo Cicadivetta goumenissa sp. n. Poleg morfoloških značilnosti je za tovrsto značilen napev s hitrim sosledjem kratkih ehemov (SE, trajanje 26+_7 ms) z nekaj SE do več kot 500 SE v frazi s ponavljalno frekvenco 13-22 SE/s , ki ga prekinjajo daljši ehemi (LE, trajanje 535+_88 ms). Izjemoma so v napevu tudi sekvence z daljšimi LE (760+_284 ms) in z le nekaj SE med njimi ali celo brez njihTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaPrirodoslovni muzej Slovenije
