**Pselligmus**
**Definition**
Pselligmus is a genus of spiders belonging to the family Nemesiidae. It is characterized by specific morphological traits that distinguish it from other genera within the family.
**Overview**
Pselligmus was first described in the early 20th century and includes species primarily found in South America. Members of this genus are mygalomorph spiders, known for their robust bodies and burrowing behavior. They typically inhabit forested areas where they construct silk-lined burrows or retreats.
**Taxonomy and Classification**
The genus Pselligmus falls under the order Araneae and suborder Mygalomorphae. It is closely related to other genera within Nemesiidae, sharing common features such as cheliceral structure and spinneret arrangement.
**Habitat and Behavior**
Pselligmus species are ground-dwelling spiders that prefer humid environments. Their burrowing lifestyle aids in protection from predators and environmental extremes. These spiders are generally nocturnal hunters, feeding on insects and other small arthropods.
**Significance**
While not widely studied, Pselligmus contributes to the biodiversity of South American arachnofauna and plays a role in controlling insect populations in its ecosystem.
**Meta Description**
Pselligmus is a genus of mygalomorph spiders in the family Nemesiidae, native to South America. These ground-dwelling spiders are known for their burrowing habits and ecological role as insect predators.
