Distribution ( Fig. 12 ). This species has been recorded from both New Caledonia and Vanuatu ( Lieftinck 1975 ; Tsuda 2000 ). In New Caledonia , we recorded it from more than 25 localities on Grande Terre. Habitats. Trineuragrion percostale occurs in the same habitats as C. uniseries , in small, fast-flowing, open or forested creeks. This species seems to avoid ultramafic soils. Biology and behaviour. Adults emerge in the morning, not far above the water in quiet parts of the stream along the banks. Adults remain around water. Males do not seem to be territorial and they fly above fast-flowing water. Status. Common on Grande Terre and has also been reported for Vanuatu , we rank its conservation status as LC.
