Acmaeodera pubiventris yumae
Knull, 1937
Acmaeodera pubiventris yumae is a of jewel beetle in the Buprestidae, described by Knull in 1937. It belongs to the nominate subgenus Acmaeodera (s. str.) and is part of a associated with woody plants in western North America. The subspecies epithet "yumae" suggests a connection to the Yuma region, though precise type locality details are not provided in available sources. Like other members of Acmaeodera, are likely active during warmer months and associated with flowers or host plant foliage.

Identification
Distinguished from other Acmaeodera pubiventris by subtle morphological differences, likely involving elytral pattern, , or coloration. The nominate subspecies A. p. pubiventris and A. p. lanata are also western North American ; A. p. lanata is specifically noted from more northern and montane areas. Accurate identification requires examination of or detailed original description. Specimens may show the yellow and/or red markings on black background typical of the Acmaeodera (s. str.) subgenus.
Habitat
Associated with dry, rocky in western North America, likely in desert or semi-desert scrub and open woodland environments. Related occur in montane and foothill settings with Cercocarpus and other woody Rosaceae.
Distribution
Recorded from the , specifically Middle America and North America. The epithet "yumae" implies occurrence in or near the Yuma area of southwestern Arizona or adjacent regions of California and Sonora, Mexico. GBIF records confirm presence in the Nearctic.
Seasonality
likely active from late spring through summer (May-August), based on of related Acmaeodera in similar climates. Peak activity probably coincides with flowering of plants.
Host Associations
- Cercocarpus - probable in the Acmaeodera pubiventris complex have been associated with Cercocarpus (mountain mahogany) in western North America; specific records for A. p. yumae are not documented.
Human Relevance
Of interest to coleopterists specializing in Buprestidae; specimens contribute to understanding of Acmaeodera diversity in the desert Southwest. No documented economic importance.
Similar Taxa
- Acmaeodera pubiventris lanataOverlapping geographic range in western North America; differs in characteristics and likely occupies more northern/montane .
- Acmaeodera pubiventris pubiventrisNominate ; geographic and morphological distinctions from A. p. yumae require verification against type material.
- Acmaeodera angelicaAnother Acmaeodera (s. str.) associated with Cercocarpus in western North America; similar size and color pattern but with distinct elytral markings.

Nomenclatural note
The was described by Josef N. Knull in 1937. Knull was a prolific describer of North American Buprestidae, and many of his require modern revision to clarify subspecific boundaries and geographic limits.
Taxonomic context
Acmaeodera pubiventris belongs to the nominate subgenus Acmaeodera (s. str.), which contains numerous western North American many of which show complex patterns of geographic variation expressed as . The as a whole warrants comprehensive revision integrating molecular and morphological data.
