Conoplectus canaliculatus
(LeConte, J. L., 1849)
Conoplectus canaliculatus is a small in the , specifically within the Pselaphinae. It is one of many commonly referred to as "-loving " due to their ecological association with ant colonies. The species was first described by John Lawrence LeConte in 1849 and has a broad distribution across eastern and central North America, with records from Canada and much of the eastern and central United States.

Identification
As a member of Pselaphinae, this exhibits the characteristic compact body form and reduced typical of -loving . Members of the Conoplectus can be distinguished from related genera by features of the and elytral structure. Specific diagnostic characters for C. canaliculatus include the presence of a distinct longitudinal groove or channel (reflected in the species epithet "canaliculatus," meaning "channeled" or "grooved") on some body surface, though precise identification typically requires examination of male and other fine morphological details. The species is small, likely measuring only a few millimeters in length.
Habitat
Like other Pselaphinae, this is typically found in association with colonies. The specific microhabitat preferences are not well documented, but ant-loving in this generally inhabit leaf litter, soil, and decaying matter in forested and woodland environments where ants are present.
Distribution
The has a broad distribution across eastern and central North America. Records exist from Canada (Ontario and Quebec) and throughout much of the eastern and central United States, including Alabama, Arkansas, Connecticut, Delaware, Florida, Georgia, Iowa, Illinois, Indiana, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Missouri, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Virginia, Wisconsin, and West Virginia.
Host Associations
- Ants - commensal or symbioticAs an -loving , this lives in association with ant colonies. The specific nature of the relationship (whether commensal, mutualistic, or parasitic) has not been documented for this species.
Ecological Role
As a member of the Pselaphinae, this likely plays a role in through its association with soil and leaf litter microhabitats. The relationship with may involve on ant-associated organisms, scavenging, or other interactions that remain poorly understood for this particular species.

Taxonomic history
The was described by John Lawrence LeConte in 1849, one of the most prolific of the 19th century. The Conoplectus is classified within the tribe Trogastrini of the Pselaphinae.
Collection and study challenges
Like many Pselaphinae, this is rarely encountered by casual observers due to its small size and cryptic habits. Specialized collection techniques, such as sifting leaf litter and soil or using , are typically required to document its presence. The limited number of observations in databases such as iNaturalist (only 2 observations as of the knowledge cutoff) reflects this difficulty of rather than true rarity.
