2- Telephanus atricapillus(Black-headed Silvanid Beetle)
- Telephanus lecontei
Telephanus is a of beetles in the Silvanidae, first described by Erichson in 1846. The genus contains over 100 described distributed primarily in the Americas, with records extending from North America through Central America to South America. Species in this genus are classified within the tribe Telephanini, Brontinae. The genus has been subject to taxonomic revision, with many species described by Grouvelle, Nevermann, and Sharp in the late 19th and early 20th centuries.

Identification
Members of Telephanus can be distinguished from other silvanid by their placement in the tribe Telephanini, though specific diagnostic features for the genus as a whole are not consistently documented across . The genus Brontes, also in the Brontinae, is a related group that may require careful comparison. Individual species vary considerably in size, coloration, and body form, making genus-level identification characters difficult to generalize without reference to or specialized keys.

Habitat
Based on collection records and distributions, Telephanus species are associated with forested and woodland across their range. Several species have been recorded from tropical and subtropical regions of Central and South America, suggesting preference for humid environments. The species Telephanus velox has been collected in eastern North America, indicating temperate habitat in some lineages.
Distribution
The is distributed throughout the Americas. North American records include the United States (Vermont) and Mexico. Central American records include Rica, Panama, and the Caribbean (Cuba, Haiti, Guadeloupe). South American records include described from Argentina, Brazil, and other regions. The distribution pattern suggests a primarily Neotropical radiation with some temperate species.
Human Relevance
Some Telephanus have been documented in association with stored products. Telephanus tabaciphilus, as indicated by its specific epithet, has been recorded in association with tobacco. The species Telephanus velox has been noted in proximity to human structures in North America. Overall economic impact appears limited compared to other stored product pests in Silvanidae.

Taxonomic history
The was established by Wilhelm Ferdinand Erichson in 1846. Major contributors to -level include Antoine Henri Grouvelle (French entomologist, active 1880s-1910s), Hermann Nevermann (German entomologist, active early 20th century), and David Sharp (British entomologist, late 19th century). The high number of species described by these authors reflects intensive collecting in Central and South America during this period.
Species diversity
The contains approximately 120 described , making it one of the more species-rich genera in Silvanidae. Species-level identification is challenging due to the large number of , many described from limited material, and the absence of comprehensive modern revisions for most species groups.
