Phisidini
. Widely distributed in the Polynesian/Melanesian area.
HABITAT AND LIFE HISTORY TRAITS. — This species occurs in anthropized areas near and/or on the shore, rarely in slightly more elevated areas. Specimens stay on foliage of large leaves-bearing trees (
Terminalia catappa
,
Barringtonia
sp.
, etc.) and shrubs (
Hibiscu
s sp., etc.). Often several specimens can be observed on the same plant.
DESCRIPTION COMPLEMENT
Stridulatory file with 64 lamellar teeth and few spinules on both sides of the file (
Fig. 21C
).
CALLING SONG (
FIG. 22
)
Males call during night. Often, several males are irregularly alternating their call. Th e call of
P. holdhausi
consists of echemes of irregular length lasting 856.7 ± 981.4 ms (min: 3.0; max: 4504.9), irregularly separated by 7.494 ±
22.235 s
(min: 0.038; max: 98.026) long pauses.Within echemes, the syllable rate is 39.2 ±
1.5 s
(min: 35.6; max: 42.4). Th e principal frequencies of the call are 23-26 kHz.
