Figs 15–21 View Figs 15–29 .
MATERIAL. 1. Russia, Moscow Oblast, Mytishchi District, env. Pirogovo Town, dry meadow, from Trifolium repens L., 2.VII.1988, signals of one male recorded at 27 °C ( Figs 15, 17, 19 View Figs 15–29 ). 2. Russia, Moscow Oblast, Serpukhov District , env. Luzhki Village , dry meadow near the Oka River , from Medicago falcata L., 30.VI.1988, signals of two males recorded at 27 °C ( Figs 16, 18, 20–21 View Figs 15–29 ) .
SIGNALS. Calling signal is a phrase lasting for about 10– 20 s and consisting of three different parts. The first part consists of rather variable syllables repeating with a period of ca. 0.8– 1.1 s. The second part consists of high-amplitude syllables including two pulses each or, more rarely, of single pulses; in our recordings, syllable repetition period in this part averages 50–60 ms. The third part has considerably lower amplitude compared to the second one and is similar to the 2 nd part of a phrase of P. elongatus (cf. Figs 13 View Figs 1–14 and 19–20 View Figs 15–29 , the 2 nd halves of oscillograms); syllable repetition period in this part averages 40–50 ms. Male can produce single phrases with irregular intervals ( Fig. 15 View Figs 15–29 ) or sing almost continuously for several minutes ( Fig. 16 View Figs 15–29 ). In the latter case phrases can follow each other without gaps (the end of the previous phrase presents in the beginning of the oscillogram on Fig. 16 View Figs 15–29 ).
PENIS SHAPE. Penis broad in lateral view, with two pairs of processes in the middle of a ventral part and a pair of processes on the sides closer to the dorsal edge; apical part simple, rounded ( Fig. 21 View Figs 15–29 ).
