Figs 32–34 .

MATERIAL. Primorskiy Krai, Khasan District, “Kedrovaya Pad’ ” (presently, “ The Land of Leopard ”) Nature Reserve , environs of Primorskiy Village , 17.VIII.2010, signals of one male recorded at 25 °C .

SIGNALS. The male calling signal consists of syllables lasting for 2.6– 2.9 s and separated by gaps of approximately from 3 to 7–8 s ( Figs 32–33 ). In our recordings, each signal includes 2–4 syllables. The syllable pattern is indistinct, and individual pulses in it are almost indistinguishable ( Fig. 34 ).

REMARKS. In terms of the temporal pattern, the male calling signals of E. pallidipennis are almost the same as those of E. sulphurella (Zetterstedt, 1828) , but distinctly differ from the signals of E. koszevnikovi (Zakhvatkin, 1938) [ Tishechkin, 2000: 51–54; figs 480–494].

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.

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.
