Griburius rileyi
Sassi, 2023
Bold-spotted Griburius
Griburius rileyi is a recently described of case-bearing leaf beetle in the Chrysomelidae, Cryptocephalinae. The species was described by Sassi in 2023 and is distinguished by bold spotted patterns on its . Like other members of the Griburius, are associated with oak woodlands and are attracted to ultraviolet light sources. The specific epithet honors Edward Riley, a prominent coleopterist and indefatigable collector of beetles, particularly known for his contributions to cerambycid and chrysomelid .

Identification
Habitat
Oak woodlands and montane forest . Associated with Quercus and other woody vegetation typical of southwestern North American oak .
Distribution
Southwestern United States and adjacent Mexico; specifically recorded from montane oak woodlands in Arizona and New Mexico. The type material was collected in the Chiricahua Mountains of Arizona.
Seasonality
have been recorded in late spring to early summer (May-June), with peak activity likely corresponding to oak foliage flush. Attracted to blacklights during evening hours.
Host Associations
- Quercus - association found in oak woodlands; larval unconfirmed but likely oak foliage given -level associations.
Behavior
are and attracted to ultraviolet light sources. This has been documented at blacklight setups in montane oak-pine woodlands, where individuals were observed alongside other cryptocephaline leaf beetles.
Ecological Role
As a leaf beetle, likely functions as a folivore in oak woodland . The -level association with oaks suggests a role in nutrient cycling through leaf consumption, though specific ecological impacts of this are undocumented.
Human Relevance
Named in honor of Edward Riley, recognizing his substantial contributions to and collecting. The serves as an example of eponymous in entomology, where the specific epithet 'rileyi' commemorates a respected coleopterist.
Similar Taxa
- Griburius montezuma with similar preferences in montane southwestern North America; distinguished by elytral pattern and possibly distribution.
- Other Griburius species-level similarities in and ; G. rileyi specifically distinguished by bold spotted elytral pattern.
More Details
Nomenclatural history
The specific epithet 'rileyi' honors Edward Riley, following the convention of using the '-i' suffix for male eponyms. This continues a pattern in entomology where prominent collectors and taxonomists are recognized through epithets, as seen in the related cerambycid Saperda lateralis rileyi (Schiefer & Newell, 2010).
Collection method
Documented collection via ultraviolet light trapping (blacklighting) in montane oak-pine woodland at approximately 1650 meters elevation. This method is particularly effective for nocturnally active chrysomelids in the Cryptocephalinae .
