Identification

Identification to level requires examination of genitalic and other fine structural characters typical of the Scaphinotus. The condition distinguishes it from fully winged , but not from other brachypterous Scaphinotus species. Geographical distribution in California forests provides a contextual clue, but precise identification demands taxonomic expertise and reference to original species description.
