Definition
Hamotus elongatus is the scientific name of a species of rove beetle in the family Staphylinidae, subfamily Pselaphinae.
Overview
The genus Hamotus comprises small, ant‑associated (myrmecophilous) beetles commonly referred to as ant‑loving beetles. Species of this genus are distributed primarily in the Nearctic region, with many records from North America. H. elongatus was described in the early 20th century, but detailed information on its biology, distribution, and ecology is limited in publicly available literature.
Etymology / Origin
The generic name Hamotus is derived from Greek hamōtēs meaning “hooked” or “curved,” likely referring to morphological traits such as the shape of the antennae or mandibles typical of the group. The specific epithet elongatus is Latin for “elongated,” indicating that the species exhibits a more slender or lengthened body form relative to congeners.
