TYPE LOCALITY. — Indian Ocean, Comoros archipelago, Mohéli.

ETYMOLOGY. — After the type locality, Mwali (Mohéli in Comorian).

BIOLOGY. — I collected this species in the undergrowth of a patch of preserved vegetation, on a ridge leading to the central crest of Mohéli island.

DIAGNOSIS. — Males are characterised by terminalia ( Fig. 5 View FIG G-J). Cerci stout, distal part bent, almost at right angle, with apex pointing. Epiphallus cephalic lobe usually not enlarged ( Fig. 6G View FIG ); one specimen with enlarged cephalic lobe ( Fig. 6I View FIG ).

DESCRIPTION

In addition to generic characters.

T1 with 7 (rarely 6)/7 subapical spurs. F1 with 6/5 spurs (6/ 6 in one male paratype). T2 with 5-6/5-6 ventral spurs. T2 dorsal subapical spur lacking in one side in female allotype.

Male Wings: file with 96-106 lamellar teeth ( Fig. 7D, E View FIG ). Cerci stout, distal part bent, almost at right angle, with apex pointing ( Fig. 5G, I View FIG ). Epiphallus cephalic lobe usually not enlarged (n = 4, Fig. 6G, H View FIG ), distinctly enlarged in one specimen ( Fig. 6I View FIG ).

Female SGP with a very minute median emargination ( Fig. 9D View FIG ). Hindward projecting folds of tergite VIII broadly rounded, ventral lobe long and wide ( Fig. 9C View FIG ).

BIOACOUSTICS ( FIG. 10B View FIG )

One singing male has been recorded in captivity, at 22h00, 27°C.

The call of C. mwaliensis n. gen., n. sp. consists of long irregular echeme-sequences lasting tens of seconds and separated by breaks lasting hundreds of seconds. Echeme-sequences are made of echemes lasting 60.9 ms-99.6 ms (average: 82.3 ms) and separated by 149.5 ms-13 287.3 ms (average: 1245.5 ms). Echemes are usually disyllabic, each syllable lasting 21.8 ms-38.3 ms (average: 25.6 ms); the disyllabic echemes are separated by gaps lasting 10.7 ms-28.1 ms (average: 13.5 ms). Fundamental peaks at 30.5 kHz.
