Hamotus elongatus
(Brendel, 1890)
Hamotus elongatus is a of rove beetle ( Staphylinidae) first described by Brendel in 1890. The species belongs to a commonly referred to as 'ant-loving beetles' due to their association with colonies. Records indicate presence in the southwestern United States, specifically Arizona and New Mexico. Like other members of the genus Hamotus, this species is likely myrmecophilous, living in close association with ants, though specific ecological details remain poorly documented.

Identification
Distinguished from other Hamotus primarily by its more elongated body proportions, as indicated by the specific epithet. Accurate identification to species level requires examination of genitalic structures and comparison with . The Hamotus is characterized by small size, compact form, and association with ants, separating it from superficially similar staphylinid genera.
Appearance
As a member of the Hamotus, H. elongatus is a small rove beetle with the characteristic abbreviated that leave most of the exposed. The epithet 'elongatus' suggests an elongated body form relative to . Detailed morphological descriptions are sparse in available literature.
Habitat
Specific details for H. elongatus are not documented. Based on -level patterns, in Hamotus are typically found in soil and leaf litter in association with nests. The recorded distribution in Arizona and New Mexico suggests occurrence in arid and semi-arid environments of the southwestern United States.
Distribution
Documented from Arizona and New Mexico, United States. GBIF records confirm presence in these two states within the southwestern North American region. No additional distribution records are available.
Host Associations
- ants - myrmecophily-level trait; specific for H. elongatus unknown
Behavior
Presumed myrmecophilous based on affiliation, though specific behavioral observations for H. elongatus are not documented. Members of Hamotus are known to inhabit nests, where they likely feed on organic debris, ant secretions, or other materials within the colony.
Ecological Role
As a myrmecophile, likely functions as a commensal or within colonies. The precise ecological role—whether neutral, beneficial, or potentially detrimental to ants—has not been studied for this .
Human Relevance
No documented economic or medical importance. Like most small staphylinids, this is of interest primarily to systematists and students of myrmecophilous diversity.

Taxonomic note
The Hamotus is part of the large rove beetle Staphylinidae, one of the most diverse families of organisms on Earth. The 'ant-loving beetle' applied to this genus reflects a well-established pattern of myrmecophily, though the evolutionary and ecological dynamics of these associations remain understudied.
