DIAGNOSIS. — Male brachypterous, wings distinctly longer than Pro ( Fig. 12A, B View FIG ; shorter in Comorophisis mayottensis n. gen., n. sp.); rod of epiphallus narrowed before the cephalic lobe (dorsal view; Fig. 11D View FIG ; not narrowed in C. mayottensis n. gen., n. sp.); female FW longer than Pro; female SGP posterior margin weakly projecting ( Fig. 13B View FIG ; distinctly projecting in C. mayottensis n. gen., n. sp.)

T1 with 7/7 subapical spurs; F1 with 5/4 (5 in one female allotype side) spurs; mid trochanteral spine present in male holotype and female allotype, not in female paratype; T2 with 6/5-6 subapical spurs; F2 with 3/2 spurs.

Male

Wings ( Fig. 12 View FIG A-C): distinctly longer than Pro. File with 117 lamellar teeth ( Fig. 12C View FIG ). Epiproct small, fitting in a semicircular notch of the last tergum, with a distinct longitudinal depression ( Fig. 11A View FIG ). Paraprocts small, hardly visible in dorsal view ( Fig. 11A, B View FIG ). Cerci with a wide basis, reduced right after the basis,cylindrical, regularly bent inwards ( Fig. 11 View FIG A-C). SGP posterior margin sinuate, almost strait ( Fig. 11B View FIG ). Genitalia ( Fig. 11D, E View FIG ): epiphallus rod short, weakly bent downwards apically (side view; Fig. 11E View FIG ); rod widened in the middle and narrowed before the cephalic lobe (dorsal view; Fig. 11D View FIG ); cephalic lobe shortly divided apically, forming two short diverging spines (in dorsal view; Fig. 11D View FIG ).

Female

FW longer than Pro.SGP posterior margin weakly projecting,with a minute median emargination ( Fig.13B View FIG ).

Measurements

See Table 6.

BIOLOGY. — I observed this species in poorly preserved gardened forest, mostly on the invasive plant species Psidium cattleianum around the abandoned village of Nioumbadjou.

BIOACOUSTICS ( FIG. 14A View FIG )

One singing male has been recorded in captivity, at 5h00 AM, 24°C.

The call of C. labati n. gen., n. sp. consists of long irregular echeme-sequences lasting 5 s-10 s

and separated by breaks lasting tens of seconds. Echeme-sequences are made of sequences of regularly repeated syllables separated by breaks lasting 45 ms-1413 ms (average: 145 ms). Syllables are lasting 10.5 ms-18.9 ms (average: 14.3 ms) and are separated by gaps lasting 14.2 ms-25.2 ms (average: 19.2 ms). Fundamental peaks at 32 kHz.

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

ETYMOLOGY. — After the type locality.

DIAGNOSIS. — Male micropterous, FW at most as long as Pro ( Fig. 12D, E View FIG ; longer in Comorophisis labati n. gen., n. sp.); rod of epiphallus not narrowed before the cephalic lobe (dorsal view; Fig.11I View FIG ; narrowed in Comorophisis labati n. gen., n. sp.); female FW at most as long as Pro; female SGP posterior margin distinctly projecting ( Fig. 13D View FIG ; weakly projecting in Comorophisis labati n. gen., n. sp.).

In addition to generic characters.

Male

Wings ( Fig.12 View FIG D-F): as long as Pro. File with 110 lamellar teeth ( Fig. 12F View FIG ). Terminalia ( Fig. 11 View FIG F-J): epiproct small, fitting in a semicircular notch of the last tergum, with a longitudinal depression ( Fig. 11F View FIG ). Paraprocts small, distinct in dorsal view ( Fig. 11F, G View FIG ). Cerci with a wide basis, reduced right after the basis, cylindrical, regularly bent inwards ( Fig. 11 View FIG F-H). SGP posterior margin sinuate, almost strait ( Fig. 11G View FIG ). Genitalia ( Fig. 11I, J View FIG ): epiphallus rod short, weakly bent downwards apically (side view; Fig. 11J View FIG ); rod widened toward the apex (dorsal view; Fig. 11I View FIG ); cephalic lobe divided apically, forming two diverging spines (in dorsal view; Fig. 11I View FIG ).

Female

FW at most as long as Pro.SGP posterior margin distinct ly projecting,with a distinct median notch ( Fig.13D View FIG ).

Measurements

See Table 7.

BIOLOGY. — I observed this species in well-preserved forest, near the ground, often on fern species. The ultrasound ambient noise is dominated by this species near the Fare in Bénara and near the top of Mlima Choungui.

BIOACOUSTICS ( FIG. 14B View FIG )

One singing male has been recorded in the field, at 2h00 AM, 26°C.

The call of C. mayottensis n. gen., n. sp. consists of short echeme-sequences lasting 0.7 s- 1.3 s and separated by breaks lasting tens of seconds (20-60 s). Echeme-sequences are made of 3-6 echemes.Echemes are lasting 70 ms -196 ms (average: 131) and are separated by breaks lasting 98-525 ms (average:317 ms). Within echemes, 3-8 syllables are regularly repeated. Syllables are lasting 7.3 ms-13.4ms (average:11.4 ms) and are separated by gaps lasting 14.1 ms-19.3 ms (average:16.4 ms).Fundamental peaks above28 kHz.
