( Fig. 105 )

Tramea limbata Ris, 1913 ; Tramea limbata Desjardins, 1832 ; Trapezostigma limbata Desjardins, 1832 ; Tramea samoensis Brauer, 1867 ; Trapezostigma euryale Selys-Longchamps, 1878 ; Tramea transmarina intersecta Lieftinck, 1975: 162 .

Distribution ( Fig. 106 ). Regional endemic subspecies. T. transmarina has several subspecies in southeast Asia, including Japan and also numerous islands in the Pacific ( Tsuda 2000). Tramea transmarina intersecta is known from Vanuatu ( Lieftinck 1976; Tsuda 2000) and from New Caledonia where it has recorded from more than 20 localities. Bigot (1985) caught numerous specimens in Baie de Prony. Finally, several specimens from Nouméa are held at the ONNC collection and one specimen collected in 1999 in La Foa (Pocquereux valley) is preserved in the CXMNC collection.

Habitat. It occurs in sunny standing water habitats, including along the landward border of mangroves, and also calm parts of streams and rivers. It seems to tolerate ultramafic soil.

Biology and behaviour. Its behaviour is similar to other New Caledonian Tramea Hagen, 1862 species. According to Lieftinck (1976), the larvae cannot be distinguished from T. transmarina propinqua Lieftinck, 1942 .

Status. Based on its presence at many sites and eurytopic habitat preferences, we consider the species not at risk in New Caledonia ( LC).
