In 1973 Forster & Wilton erected Amphinectidae as a family with sixteen genera from New Zealand. Several more genera were added from Australia and South America. These are nocturnal forest dwellers in moist habitats, sometimes underground. They are found in rotting logs and other moist habitats. The family is divided into three subfamilies, Amphinectinae, Metaltellinae and Tasmarubriinae, but these are fragile arrangements. This family like many others is hard to pin down and may not be fully resolved for many years, with the help of painstaking field work and DNA studies.
