Fornax melsheimeri
Fornax melsheimeri is a of false click beetle in the Eucnemidae. Members of this family are characterized by their inability to produce the clicking sound that defines true click beetles (Elateridae), despite similar body plans. The Fornax contains multiple North American species, though detailed species-level documentation remains limited. This species was named in honor of the early American entomologist Frederick Ernst Melsheimer.

Identification
Distinguishing Fornax melsheimeri from other Eucnemidae requires examination of specific morphological characters including pronotal shape, elytral striation patterns, and antennal structure. Separation from congeneric such as Fornax exstans and Fornax tenebrosus depends on subtle differences in body proportions and surface sculpturing. Definitive identification typically requires reference to original species descriptions or keys.
Distribution
Eastern North America; precise range boundaries have not been comprehensively documented.
Ecological Role
As with other Eucnemidae, larvae are presumed to be saproxylic, developing in decaying wood where they contribute to nutrient cycling and forest decomposition processes.
Similar Taxa
- Elateridae (true click beetles)Eucnemidae resemble true click beetles in general body form but lack the prosternal process that enables the characteristic clicking/jumping mechanism; examination of the prosternal-mesosternal junction is required for -level separation.
- Fornax exstansCongeneric with overlapping distribution; requires detailed comparison of pronotal and elytral characters for reliable separation.

Taxonomic Note
The specific epithet 'melsheimeri' honors Frederick Ernst Melsheimer (1782-1873), a German-American clergyman and entomologist who published significant early works on North American beetles. The was likely described in the 19th or early 20th century, though original publication details require verification.
Data Deficiency
This has zero observations in iNaturalist and appears to be poorly represented in modern collections or databases. Basic biological information including associations, larval , and precise distribution remain undocumented in readily accessible literature.
