3d virtual fossil dyspnoi


The Dyspnoi are a suborder of harvestmen, with about 32 genera, and about 320 described species.

Contents

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).

Distribution

The Dyspnoi are one of the most 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.
