Taphrocerus leoni
Dugès, 1891
Taphrocerus leoni is a of jewel beetle ( Buprestidae) described by Dugès in 1891. The species was historically considered Mexican but has been documented in the United States, with confirmed records from upper Miller Canyon in the Huachuca Mountains of southeastern Arizona. are associated with sedges and can be collected by sweeping vegetation in riparian areas. The species is distinguished from by its larger size, shiny appearance, and distinct pubescent maculations.

Identification
Distinguished from Taphrocerus chevrolati and T. sulcifrons by its larger size, shinier appearance, and distinct pubescent maculations. In the field, these characteristics allow for ready identification without microscopic examination. The occurs sympatrically with T. chevrolati and T. sulcifrons in southeastern Arizona.
Appearance
are relatively large and shiny compared to other Taphrocerus , with distinct pubescent maculations visible in the field. The overall body form is typical of the —elongate and somewhat flattened, with the characteristic buprestid body plan. Specific coloration details are not documented in available sources.
Habitat
Riparian areas with sedges (Carex and related ). In the Huachuca Mountains, found in a small patch of mixed sedges, rushes, and grasses along a creek bed at approximately 5,000 feet elevation in montane oak-juniper woodland.
Distribution
Originally described from Mexico. In the United States, documented from the Huachuca Mountains, Cochise County, Arizona (upper Miller Canyon). Represents a northward range extension from the Mexican type locality.
Seasonality
Active in late May to early June based on collection records from southeastern Arizona. have been collected by sweeping vegetation during this period.
Host Associations
- Sedges (Carex and related genera) - /larval collected by sweeping sedges, rushes, and grasses in riparian areas; likely larval development in stems
Behavior
are active during daylight hours and can be collected by sweeping vegetation. They have been observed flying and landing on sedge vegetation. No specific mating or documented.

Taxonomic History
Historically considered a Mexican , T. leoni was not formally recorded from the United States until collections in the Huachuca Mountains of Arizona in 2022. The species was documented during a revisionary study of North American Taphrocerus fauna.
Collection Method
Successfully collected using a long-handled, large-rim aerial net to sweep vegetation in the upper and along creek beds, a technique that has proven effective for sampling Taphrocerus that occur in dense riparian vegetation.
