Nisaxis tomentosa
(Aubé, 1833)
Nisaxis tomentosa is a of in the , specifically within the -associated Pselaphinae. It has been recorded across a broad geographic range spanning North America, the Caribbean, and South America. The species epithet 'tomentosa' refers to a densely hairy or woolly appearance.

Identification
Members of the Nisaxis can be distinguished from related pselaphine genera by features of the and elytral structure. Nisaxis tomentosa specifically may be recognized by its tomentose (densely hairy) , though precise diagnostic characters require examination of male and other microscopic features typical of the tribe Brachyglutini.
Habitat
As a member of the myrmecophilous Pselaphinae, this is typically found in association with colonies. Specific microhabitat details are not well documented, but related species occupy leaf litter, soil, and decaying wood in forested and semi-open environments.
Distribution
Recorded from Canada (Ontario), the United States (Alabama, Connecticut, District of Columbia, Delaware, Florida, Illinois, Louisiana, Maryland, Mississippi, North Carolina, Nebraska, New Jersey, New York, Oklahoma, Texas, Virginia), and the Cayman Islands (Grand Cayman). The broad transcontinental range suggests either high capability or cryptic complexity.
Host Associations
- Formicidae - myrmecophilousAs a pselaphine , this is -associated, though specific ant species are not documented
Behavior
Myrmecophilous; lives in close association with colonies, though the specific nature of this relationship (inquilinism, , or other) has not been described for this .
Ecological Role
Pselaphine contribute to in forest through their association with and occupation of soil and litter . Their precise ecological functions within ant colonies remain understudied.

Taxonomic History
Originally described by Aubé in 1833, this has undergone subsequent taxonomic revision within the complex Pselaphinae. The broad geographic distribution warrants further study to assess potential cryptic diversity.
Data Gaps
No published studies specifically address the biology, , or of Nisaxis tomentosa. Most available information derives from museum specimen records and taxonomic catalogs.
