Morphological description: see the references above; Ramme 1951 (as I. brevipennis ); Bey-Bienko 1954 (as I. brevipennis and partly as I. pyrenaea ); Kis 1960 (as I. brevipennis —partly?); Harz 1969 (as I. brevipennis ). Bioacoustics: Nagy et al. 2003; Heller et al. 2004. Karyotype: Warchałowska-Śliwa and Maryanska-Nadachowska 1992 (as I. brevipennis ); Warchałowska-Śliwa et al. 2008.

This species is well characterised in the above mentioned literature sources. It was known to occur in the Carpathian Basin westwards reaching Western Hungary and Austria in the region of Vienna. However, a single specimen labelled “Coll. Br.v.W. | Montenegro | Erber” ( Figs 51, 100 ) found in the NMW collection fits well with I. camptoxypha (possessing 71 stridulatory teeth). Yet, it is not known whether this locality is correct or, if so, the case concerns an undescribed taxon. The female specimens from Macedonia (F.Y.R.O.M.), recorded by Chobanov and Mihajlova (2010) as I. aff. brevicauda , are now considered closely related to I. camptoxypha and thus referred here. Yet, the species status of the specimens resembling I. camptoxypha from the Balkan Peninsula remains unclear until data on their acoustics will be gathered.
