ABSTRACT. The calling signals of males of Sphingonotus obscuratus latissimus from the vicinity of the type locality in southeastern Kazakhstan were studied. The signal consists of a sequence of syllables produced during flight and one or several syllables produced by tegmino-femoral stridulation immediately after landing. The reasons for the convergent emergence of signals produced during flight in different taxa of Oedipodinae are discussed.
KEY WORDS: grasshopper, Acrididae, Oedipodinae, Sphingonotus obscuratus latissimus, calling signal, flight display, acoustic communication.
