Some species in the subfamily Adaeinae are almost Script error: No such module "convert". long. Legs are almost always short, measuring Script error: No such module "convert".. The armed pedipalps are large, and much stronger than the legs.[1]

Distribution

Triaenonychidae are found in North and South America, Japan and Korea, Australia and New Zealand, and Madagascar.[1]

Relationships

The Triaenonychidae should probably split into at least two families. The genera from the Australian region are considered Triaenonychidae sensu stricto, and may include the strange Synthetonychiidae; the northern species should be grouped with Travuniidae.[1]
