Abstract- 'This study is based on collections of harvestmen gathered from most parts of New Zealand. The morphology of structures of taxonomic significance is described and figured, and the value of the male genitalia as a taxonomic character is emphasised. A brief account of the biology of the group is given. The widespread occurrence of polymorphism among the New Zealand forms is recorded and discussed under two headings- (1) Sexual dimorphism, and (2) Male dimorphism. Sexual dimorphism is well known in the Opiliones but male dimorphism has not been previously recorded. Keys to all families, sub-families, tribes, genera, sub-genera, species and sub-species are given. The main division of the family Triaenonychidae are revised. Two sub-families and three tribes are recognised. Four genera and three sub-genera are newly described and a new family Synthetonychidae is established. The number of species and sub-species known from New Zealand is increased from 30 to 152, all of which are endemic. Two species which have not been found in New Zealand since being described are considered to be exotic' SCARCE.
