Hemicordulia hilaris Lieftinck, 1975: 154 .

Distribution (Fig. 57). Pacific-wide. This species is recorded from more than 15 localities of Grande Terre but its distribution is not continuous. Almost all localities are south of the Yaté lake. Bigot (1985) collected some specimens in Dumbéa.

Habitat. Hemicordulia hilaris seems to prefer ponds but can sometimes be observed near rivers. It prefers sunny and shallow swamps and ponds with very dense, low growing reed beds. The species tolerates ultramafic soil.

Biology and behaviour. Adults often wander far from water. Males patrol oviposition sites. Mating was not observed, but females lay their eggs in the same way as the previous species. Exuviae are found hanging, slightly inverted, on rock walls out of the water.

Status. In New Caledonia, the species occurs in small populations in restricted areas. Therefore, we consider this species to be locally VU.
