MATERIAL. Greece, Korfu Island , environs of Nissaki Village, ca 12 km north of Kerkyra, from Laurus nobilis L., 4.VI.2018 , signals of two males recorded at 29 ° C .

SIGNALS. The male calling signal is a phrase lasting for about 10–20 s. It consists of repeating components each including several short low-amplitude syllables and one longer syllable increasing in amplitude towards the end ( Figs 35–37 ). Repetition period of these components averages 2.5– 3.5 s. The duration of longer syllables is 350–450 ms; the duration of shorter syllables is more variable and ranges from 80 to 200 ms.

Figs 29–37. Male calling signals of Deltocephalinae. 29–31 — Streptanus aemulans; 32–34 — Elymana pallidipennis; 35–37 — Synophropsis lauri. 29–30 — oscillogram and sonogram of the same signal at the same speeds, 31–37 — oscillograms. Faster oscillograms of the parts of signals indicated as “31”, “34”, and “37” are given under the same numbers. Рис. 29–37. ПриЗывные сигналы самцов Deltocephalinae. 29–31 — Streptanus aemulans; 32–34 — Elymana pallidipennis; 35–37 — Synophropsis lauri. 29–30 — осциллограмма и сонограмма одного и того же сигнала при одной скорости раЗвертки, 31–37 — осциллограммы. Фрагменты сигналов, помеченные цифрами “31”, “34” и “37”, представлены при большей скорости раЗвёртки на осциллограммах под соответствующими номерами.
