Bioacoustics of Pycna madagascariensis

Remarks.—The other species of the genus with a body length less than 37 mm and a wingspan less than 100 mm . Body length about 28–30 mm , wingspan about 91–95 mm ( Distant 1879 ; Karsch 1890 ; specimen in hand). It can be distinguished from P. angusta by the pronotum width being about 16 mm , the oblique anterior angles of the pronotum, the unmarked mesonotum, the hour-glass shaped fulvous mark on dorsal abdominal tergites 1–3 on the otherwise piceous abdomen, the absence of a broad piceous margin on the opercula, and the piceous external margin of the hind wings. The song is a series of syllables that increase in intensity followed by a short tone of decreasing intensity with peak energy about 5 kHz but including a series of higher frequency harmonics ( Boulard 2006b ; 2008 ). Distribution.—The species is only known from Madagascar ( Metcalf 1963a ; Duffels & van der Laan 1985 ; Sanborn 2013 ; 2020). The species has been reported from Tamatave, western Madagascar and Antananarivo , central Madagascar ( Karsch 1890 ; Distant 1879 ; Jacobi 1917 ). Material examined.—“ Madagascar / Macvatanana” one male (AFSC).
