Abstract
A species known from earlier behavioural studies as "Holoplatys sp.", is described as Trite pollardi sp. nov. Within the genus Trite, two species groups are distinguished: the planiceps-group (found in New Caledonia, New Zealand, Lord Howe Island and Norfolk Island) and the incognita-group (limited to New Zealand). The three alternative scenarios of the Trite origin, relationships and radiation in New Zealand, New Caledonia and Lord Howe Island are discussed. Three species are considered to be excluded from Trite.
