Abstract
The New Zealand species referred to Allodiscus Pilsbry, 1892 during the last 60 years are evaluated. A total of 60 species are recognised, of which 37 are described as new. The taxa are described, they are illustrated by colour photographs and scanning electron microscope images, their distributions are described andmapped, and their biology and conservation are briefly discussed. Pseudallodiscus tataensis Climo, 1971 is referred to Allodiscus [s. lat.].Three new genera are introduced: Granallodisus (for Helix granum L. Pfeiffer, 1857 and two new species), Costallodiscus (for three new species) and Canallodiscus (for Allodiscus fectoloides Dell, 1955, Phelussa elliottae Gardner, 1968 and a new species). Hirsutodiscus Climo, 1971 is elevated to generic status. Lectotypes are designated for Helix dimorpha Reeve, 1852, Pitys cryptobidens Suter, 1891, Helix venulata L. Pfeiffer, 1857, Nanina tullia Gray, 1850 and Psyra godeti Suter, 1891. Neotypes are designated for Helix granum L. Pfeiffer, 1857 and Charopa miranda Hutton, 1883.
