" Body small (more robust in female), length 8.45–10.00 mm, ); in female length 9.30–10.70 mm. Caledonica longicollis is a very rare species, for a hundred years known only from the female holotype. It appears to be a strictly forest species. At the end of the year 2004, a population was discovered in a humid primary forest near Bouirou, loca- lized in a small area of young trees with narrow trunks often densely covered with mosses. Adults were observed sitting on the trunks even during continual heavy rains, sometimes with raindrops trickling from their bodies and heads. In the mountains 15 km SE of Pouebo, a single female was caught deep inside a primary forest. In the vicinity of Touho, a single male was found in forest remnants. It occurred there sympatrically with C. rubicondosa, C. bavayi and C. mniszechii." (KUDRNA: A revision of the genus Caledonica (Cicindelidae), 2016)
