We recorded and analysed the calling and courtship songs of the males, as well as the stridulatory movements of the hind legs. Analysis of the stridulatory leg movements allowed us to reveal more differences between both the courtship songs and the calling songs of the European species of this group. On the basis of the morphology, calling and courtship song analysis, we describe a new species, Ch. ferdinandi sp. n., from Greece (Peloponnesus) and a new subspecies, Ch. oschei pusztaensis ssp. n., from the Balkans, Hungary, Moldova and Ukraine. Ch. bruttius Fontana &amp; La Greca, 1999 is classified as a subspecies of Ch. karelini. We describe the phylogenetic relations between the European species of the Ch. albomarginatus group based on the courtship song complexity and courtship visual display.</p>

Here, we present a genetic analysis of the courtship song differences between two closely related grasshopper species Ch. albomarginatus and Ch. oschei. Measurements of seven courtship song characters and one parameter of courtship visual display were compared among parentals, F 1 and F 2 hybrids, and backcrosses. Variation in one morphological character, the number of stridulatory pegs, was studied as well. The distributions of song phenotypes were more consistent with a type-III genetic architecture, which involves complementary or duplicate pairs of loci. We suggest that this type of architecture may provide the novel elements of the hybrid songs, even more complex than the parental ones, which may offer a new starting point for sexual selection. One parameter of the visual display appeared to be controlled by a single locus, but differences in other characters of visual display could be explained by a more complex inheritance pattern. Inheritance of the peg number differences was consistent with a simple polygenic additive model. Sex linkage and/or maternal effects were not detected for any trait. We found a disproportionate influence of the Ch. albomarginatus parent on most hybrid song characteristics and the visual display, and this may support a previously suggested idea that Ch. albomarginatus is an ancestral form and Ch. oschei is a derived species.1 aVedenina, YU.1 aPanyutin, A., K.1 avon Helversen, Otto  uhttp://www.blackwell-synergy.com/toc/jeb/20/1
