Acmaeoderopsis chisosensis
(Knull, 1952)
Acmaeoderopsis chisosensis is a of metallic wood-boring beetle in the Buprestidae. It was described by Knull in 1952. The species is found in Central America and North America, with records from the Nearctic and Neotropic regions. Based on field observations, have been collected from mesquite (Prosopis glandulosa) in sand dune of west Texas and southeastern New Mexico.

Identification
Acmaeoderopsis chisosensis can be distinguished from similar Acmaeodera by its association with the Acmaeoderopsis, which is characterized by specific morphological traits typical of this buprestid group. Field observations note that are small and vittate (striped), with a tendency to fly immediately upon disturbance when beating vegetation. They have been observed flying to the tips of high branches of mesquite trees, making them challenging to collect by standard beating techniques.
Habitat
Sand dune and adjacent sandy rangeland with mesquite (Prosopis glandulosa) woodland. Observations indicate association with blowouts and classic sand flora in dune systems. The appears to require areas with sufficient moisture from recent rainfall to trigger .
Distribution
Central America and North America. Specifically recorded from the Chihuahuan Desert region of west Texas (Kermit Sand Dunes area) and southeastern New Mexico (Mescalero Sand Dunes). The specific epithet 'chisosensis' suggests a possible type locality association with the Chisos Mountains or Chisos region of Texas.
Seasonality
active in late spring to early summer. Field records from June indicate peak activity following rainfall events that trigger . Activity appears strongly tied to recent precipitation in otherwise arid environments.
Host Associations
- Prosopis glandulosa - collected from mesquite flowers and foliage; observed flying to tips of high branches
Behavior
are and highly active, with a strong response upon disturbance. When beating mesquite, individuals fly away immediately upon hitting the sheet, making collection difficult. They have been observed flying to high branches rather than remaining on beaten foliage. Evening searches suggest adults may hide elsewhere at night, as they are not found on trees after dusk.
Similar Taxa

- Acmaeoderopsis prosopis with similar association (mesquite); field express hope in distinguishing A. chisosensis from this similar
More Details
Etymology
The specific epithet 'chisosensis' refers to the Chisos region of Texas, likely indicating the type locality or area of original discovery.
Collection challenges
This presents significant collection difficulties due to its rapid response and preference for high branches. Successful collection requires aerial netting of flying or sweeping vegetation rather than standard beating techniques.
