Myrmecocephalus cingulatus

(LeConte, 1866)

Myrmecocephalus cingulatus is a small (: Aleocharinae) in the tribe Falagriini. It occurs across eastern North America from Canada to the southern United States. The name 'Myrmecocephalus' (-) refers to the ant-like appearance of these . This is rarely collected and poorly known biologically.

Identification

Distinguished from other Myrmecocephalus by genitalic characters and subtle external features requiring microscopic examination. The -like body form separates it from most other , though it may be confused with other myrmecophilous or myrmecoid aleocharines. Accurate identification to species level typically requires dissection and comparison with or authoritative .

Appearance

Small with compact, -like body form. Short leave most of exposed, typical of . and often appear constricted, contributing to the myrmecoid (ant-mimicking) silhouette. Body coloration and exact size measurements are not well documented in accessible literature.

Habitat

Specific associations are poorly documented. Related in Falagriini are often found in decaying matter, leaf litter, and other moist microhabitats. The species has been collected in wooded and semi-wooded areas across its range.

Distribution

Eastern North America: Canada (Nova Scotia, Ontario, Quebec) and USA (Alabama, Arkansas, District of Columbia, Florida, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Michigan, Missouri, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Virginia, Wisconsin, West Virginia). Records from Galapagos Islands are erroneous.

Seasonality

Collection records span multiple months, but specific seasonal activity patterns are not well documented. have been recorded from spring through fall in temperate portions of the range.

Behavior

Specific behaviors are undocumented. The -like suggests possible (ant association) or myrmecophagy (ant ), though this remains unconfirmed for this .

Human Relevance

No known economic or medical significance. Occasionally encountered by in litter and collections.

Nomenclatural note

Authority sometimes cited as MacLeay, 1871 in some databases, but original description by J.L. LeConte in 1866 is the accepted authority. The Myrmecocephalus was established by MacLeay in 1871, which may explain the confusion in some sources.

Taxonomic history

Placed in tribe Falagriini within the megadiverse Aleocharinae. The Falagriini are a moderately diverse tribe of small aleocharines, many with poorly known biology.
