Cryptocephalus mucoreus LeConte, 1859  

“Numerous authors have presented this species as a synonym of basalis. Wilcox (January 1953, p. 51) cited it as a valid species distinct from basalis and presented the characters which serve to distinguish the two. This action, I believe, was correct; however, Pallister (May, 1953, p. 28) resynonymized mucoreus with basalis, but Wilcox's treatment of 1954 (p. 382) amounted to a revalidation of mucoreus” (White, 1968).
