GREECE: Peloponnese, Messinia: Pilos, [N 36.913, E 021.696], 14 vii 87, leg. & recorded F. Willemse (studied by Heller 1988 and figured in Ragge & Reynolds 1998; recording probably overload).

In the field, the songs of all our specimens were recorded in the evening or at night. They consisted of long sequences of syllables (largest recorded duration of a sequence 203 s). The syllables follow each other quite closely ( Fig. 2 View FIGURE 2 , 3 View FIGURE 3 ), but are separated by short intervals during which the tegmina are motionless ( Fig. 4A View FIGURE 4 ). The long syllables are presented in a quite slow rhythm ( SRR 0.5–1.2 Hz) and contain each about 100 impulses ( Tab. 1 View TABLE 1 ) with the exception of one specimen with shorter syllables (only 41 impulses). This animal, however, has roughly the same high number of stridulatory teeth as one with ‘normal’ song ( Tab. 1 View TABLE 1 ).

The frequency spectrum of the male calling song has a broad maximum around 15–20 kHz ( Fig. 5 View FIGURE 5 ) or near 30 kHz (another animal).

Males and females produce also sounds when roughly handled or disturbed. These sounds are variable, but contain long series of impulses probably produced during opening and closing of the tegmina ( Fig. 4C, D View FIGURE 4 ) and can in males be similar to syllables of the calling song (compare Fig. 4B and C View FIGURE 4 ).

Compared to the other studied species, the male tegmina are intermediate in size ( Fig. 6A View FIGURE 6 ; from specimen preserved in ethanol) with a relatively small mirror on the right tegmen. The stridulatory file of the male is situated on the underside of the left tegmen and carries about 125 teeth ( Fig. 7 View FIGURE 7 ; Tab. 2 View TABLE 2 ). In the middle of the file the inter-tooth intervals are about 43 µm. The stridulatory file of the female is situated on the upper side of the concave surface of the right tegmen ( Fig. 8A View FIGURE 8 ). Here the teeth are quite regular ( Fig. 8B View FIGURE 8 ) with inter-tooth intervals about 28 µm in the middle of the file. Other short veins near to the outer edge of the tegmen carry also mostly irregular pegs, but they are certainly not used for sound production. On the left tegmen at the corresponding place a non-functional file (no scraper available) is situated ( Fig. 9A View FIGURE 9 ). On some veins of the upper side of the tegmina, e.g. on those framing the mirror at the posterior edge, the males have also pegs which are similar in size to that of the females (compare Fig. 8B, C View FIGURE 8 ).

Ecology. The species is widespread in Crete with most localities below 450 m a.s.l. ( Willemse & Kruseman 1976). It is found in dry habitats, often on low prickly bushes, as described by Willemse et al. (2018).
