Bioacoustics of Rodriguesiophisis spinifera

Male. Wings. File with 65–70 lamellar teeth (average: 68, Fig. 85 ). Terminalia. Epiproct very small, fitting in a notch of the last tergum ( Fig. 76 ). Paraprocts circular, hardly visible in dorsal view ( Figs. 76, 80 ). Cerci angled at the basis; bent inwards, with a bulge on the basal bent ( Fig. 76, 80 ). Subgenital plate posterior margin sinuate, almost strait; with one posterior projection on each side; the styli/projection limit weakly distinct ( Fig. 77 ). Genitalia. Epiphallus rods regularly arched (in side view, Fig. 82 ); diverging (in dorsal view, Fig. 81 ). Female. Subgenital plate with parallel lateral sides; posterior margin convex ( Fig. 78 ). Ovipositor curved upwards distally; ventral and dorsal valves weakly serrated apically ( Fig. 86 ). Color. Green with darkened file vein (males) and ovipositor apex (females). Bioacoustics. Fig. 87 . Males are singing by night hours, often on Latania verschaffeltii . Males are usually moving while calling. Above 20°C, the call of this species consists of short echemes (8.3 ± 0.2 s ), with a distinct acceleration of syllables rate at the beginning of the echeme and a deceleration at the very end (unlike the song of the other Mascarene Phisidini species). Syllable rate at the beginning (5 first): 22 ± 2 syllables/s at the middle: 45 ± 1 syllables/s; at the end (5 last): 31 ± 2 syllables/s. Trains of waves forming the syllables are not resolved in natura with our recording setup ( 3 specimens recorded). The fundamental peaks around 19.5 kHz.
