1. Neomacednus marginatus (Emeljanov, 1962)

Figs 1–4 .

MATERIAL. The Russian Far East, Primorskiy Krai, western shore of the Khanka Lake, 10 km south of Turiy Rog , 19.VII.2006, signals of one male recorded at 28–30 °C .

SIGNALS. The male calling signal is a phrase lasting for 2.5–5 s ( Figs 1–2 ). The phrase consists of uniform syllables; each syllable usually reaches the highest amplitude in the middle or in the end ( Figs 3–4 ). Syllable repetition period averages 300–500 ms and gradually increases towards the end of the phrase. The pulse repetition period usually decreases sharply in the last third of a syllable.
