Dicerca callosa frosti
Nelson, 1963
Dicerca callosa frosti is a of jewel beetle in the Buprestidae. Originally described as Dicerca frosti by Nelson in 1963, it was later synonymized or treated as a subspecies of D. callosa. The epithet "frosti" honors a collector, following common practice in buprestid . Like other Dicerca species, it is a woodboring with cryptic coloration that provides camouflage against bark.

Identification
Dicerca callosa frosti can be distinguished from other Dicerca by subtle morphological characters, as is typical for this where species recognition relies on suites of characters rather than single diagnostic features. The likely shares the genus-characteristic metallic luster and bark-matching coloration. Precise identification requires comparison with and reference to Nelson's 1963 original description.
Distribution
Nearctic region; North America. Distribution records indicate presence in North America, though specific range boundaries within the Nearctic are not well documented in available sources.

More Details
Taxonomic history
Originally described as Dicerca frosti Nelson, 1963, this is now treated as a of Dicerca callosa. The basionym Dicerca frosti indicates it was first recognized at level before subspecific classification. This pattern of taxonomic refinement is common in Buprestidae, where cryptic are gradually resolved through detailed morphological study.
Observation rarity
iNaturalist records show only 13 observations for this , suggesting it is either genuinely rare, under-collected, or difficult to detect due to its cryptic habits. This low observation count contrasts with more common like D. lurida.
