Trichodes peninsularis basalis is a of checkered beetle in the Cleridae. It belongs to a of predatory beetles commonly found on flowers, where they feed on pollen and other flower-visiting insects. The subspecific epithet 'basalis' suggests a geographic or morphological distinction from the nominate form, though specific diagnostic features for this subspecies are not well documented in available sources.

Distribution
Recorded from southeastern Arizona (vicinity of Artesia) and potentially adjacent regions. The subspecific name 'basalis' may indicate a southern or basal geographic distribution relative to other of T. peninsularis.
Seasonality
have been collected in early September, with activity coinciding with blooming of composite flowers.

Taxonomic Uncertainty
The 'basalis' is recognized in some taxonomic treatments but may not be universally accepted; some authorities may treat T. peninsularis as or recognize different infraspecific arrangements.
