Species Guides
1Stenelaphus is a of longhorn beetles (Cerambycidae) in the tribe Elaphidiini, containing a single , Stenelaphus alienus. The genus was established by Linsley in 1936. Based on collection records from Arizona, have been observed at ultraviolet lights in montane canyon during summer months, suggesting activity patterns typical of many cerambycid beetles.

Identification
Stenelaphus can be distinguished from other elaphidiine by its status and the unique combination of characteristics possessed by its sole , S. alienus. Within the Elaphidiini, identification to genus requires examination of antennal structure, pronotal shape, and elytral patterns. The genus name refers to the narrow (sten-) antennal characteristics (-elaphus, from Elaphidion, a related genus).
Habitat
Based on collection records from southeastern Arizona, Stenelaphus alienus occurs in montane canyon environments within the Madrean Sky Island region. Specimens have been collected at blacklight stations in oak-pine woodlands and adjacent riparian corridors, suggesting association with mixed conifer-hardwood forest .
Distribution
Documented from southeastern Arizona, specifically the Santa Rita Mountains (Montosa Canyon) in the Madrean Sky Island region. The full range remains poorly known due to limited collecting effort and the ' habits.
Seasonality
have been collected in early August, indicating summer activity during the monsoon season in the southwestern United States.
Behavior
are attracted to ultraviolet light sources, indicating activity. This has been documented during blacklighting operations in montane canyon .

More Details
Taxonomic history
The Stenelaphus was established by Linsley in 1936 to accommodate the single S. alienus. The etymology combines Greek 'stenos' (narrow) with 'Elaphus' (from Elaphidion), referring to the relatively narrow antennal structure compared to related genera.
Collection methodology
The only documented specimens have been collected using ultraviolet light traps (blacklighting) at night, suggesting that daytime beating or visual searching may be ineffective for detecting this .
