BIOLOGY. — I observed this species in undergrowth of preserved areas in both Karthala and La Grille forests at around 1000 m alt.

BIOACOUSTICS ( FIG. 10A View FIG )

One singing male has been recorded in captivity, at 5h00 AM, 30°C.

The call of C. ngazidja n. gen., n. sp. consists of long irregular echeme-sequences lasting 16 s-48 s

and separated by breaks lasting tens of seconds. Echeme-sequences are made of echemes lasting 76.4-95.2 ms (average: 82.1 ms) and separated by 116.8 ms-4678.5 ms (average: 802.1 ms). Echemes are usually disyllabic (the first of a sequence is sometimes trisyllabic), each syllable lasting 13.6 ms-36.0 ms (average: 31.0 ms); the disyllabic echemes are separated by gaps lasting 7.6 ms-17.3 ms (average: 12.2 ms). Fundamental peaks at 40 kHz.
