Assamiidae

Assamiidae are a family of spiders (Arachnida ) in the order of the harvestmen ( Opiliones ). They are named after Assam, where the first Arte, Assamia wester manni, the family have been described. With more than 400 species, they are the largest group of Laniatores.

With a height of 2 to 8 mm, they are small to very large, mostly yellow to reddish brown harvestmen with black drawing on the back side. Some also have white drawings. Her legs are always long.

As is typical for harvestmen, most species of the family inhabiting soil ( litter layer ). Some species of the family are blind. They live in the soil or in caves.

The family is widespread in the tropics of the Old World. You lack in Madagascar, Europe, America and Southeast Asia. Large biodiversity have Assamidae in Central Africa, India, Australia and New Guinea.

System

The more than 250 genera and 400 species described, these strong Unmterteilung is also uncertain. The division into the mainstream of Roewer subfamilies is monophyletic and therefore not sustainable. There are at least five major groups, contradicts the definition of subdivision of Roewer.

Dampetrinae are endemic to Australia and New Guinea. Assamiinae there are mostly in India and Nepal. Trionyxellinae that are represented in India and Sri Lanka, have an average Tarsalklaue ( Pseudonychium ). Erecinae live in Central Africa. The small blind Irumuinae settle in caves and in the soil.

Assamidae are probably a sister group of the Gonyleptoidea.
