Dyspnoi
The Dyspnoi are a suborder of harvestmen, with about 32 genera, and about 320 described species.
Several fossil species are known, including two extinct families.
The superfamilies Ischyropsalidoidea and Troguloidea are monophyletic. However, the families Sabaconidae and Ceratolasmatidae are not; amongst other inconsistencies, Taracus (Sabaconidae) is a sister group to Hesperonemastoma (Ceratolasmatidae).
