Diversity

The Dyspnoi are a suborder of harvestmen, with about 40 genera, and about 370 described species.

Several fossil species are known, including two extinct families.

The superfamilies Ischyropsalidoidea and Troguloidea are monophyletic. However, the families Sabaconidae and Ceratolasmatidae were not; amongst other inconsistencies, Taracus (Sabaconidae) was a sister group to Hesperonemastoma (Ceratolasmatidae). This has been corrected by Giribet et al. (2010).

DistributionEdit

The Dyspnoi are one of the most conserved biogeographically conserved higher groups of harvestmen. None occur in the Southern Hemisphere, and most families are restricted along temperate regions. The only exceptions are some Ortholasmatinae (Nemastomatidae) inhabiting the tropics on high mountains in Mexico (Ortholasma bolivari) and northern Thailand (Dendrolasma angka). Some Troguloidea were also found in tropical regions during the Cretaceous.[1]
