Isophya clara Ingrisch & Pavićević : Ingrisch and Pavićević 2010 (sp.n.).

Morphological description and bioacoustics: Ingrisch and Paviċeviċ 2010, 2012.

Diagnosis: Ingrisch and Paviċeviċ (2010) diagnoze I. clara comparing it with I. modesta (and I. modestior — for differences see the latter paper), from which it clearly differs in song, consisting of groups of much shorter and uninterrupted syllables, pronotum and tegmen shape, number of stridulatory teeth, cercus tooth and ovipositor shape. However, in size, morphology (compare Figs 39, 64 , 88 , 113 , 144 with 40, 65, 89, 114, 150, 151) and song (compare Ingrisch and Paviċeviċ 2010: Fig. 5 A, B with present paper, Fig. 156 ), this species much resembles I. miksici , from which it seems to be isolated by the river Morava in Serbia. At similar air temperature, the song of I. clara cannot be differentiated by that of I. miksici , either using syllable duration, number of impulses or impulse interval. Unfortunately, the description lacks exact data on the number of syllables in the groups and the syllables’ interval. I. clara may be differentiated by I. miksici on account of the pronotum shape (usually with more sinuately expanded metazone in I. miksici ), the relative size of the cercal tooth (larger and longer in “typical” I. clara ). The shape of tegmina in I. clara vary (see Ingrisch and Paviċeviċ 2010), which does not allow us to make comparison with other taxa and leaves the possibility of including more than one taxon within this species. This is especially true for the specimens from the region of Belgrade showing even bigger similarity with I. miksici .

Distribution ( Fig. 192 ) and phenology: This species is herewith for the first time recorded from Bosnia and Herzegovina (see Appendix and under I. obtusa ), and already known from Montenegro, Northern Kosovo, and Western Serbia north to Belgrade. Its phenology is not known but possibly resembles that of I. miksici (see below). The imagines are collected from May to August (see Ingrisch and Paviċeviċ 2010), thus nymphs emerge probably in March–April.
