Taxonomic Notes: Despite Cockerell (1898: 29) recognizing the preoccupied name of Cresson’s species, Crawford (1926: 213) continued to recognize Panurginus clypeatus (Cresson) as a valid species, and considered Cockerell’s P. calochorti and P. verus Cockerell, 1901 as varieties of Cresson’s taxon; the synonymy was made by Cockerell (1912: 445) who on the same page also indicated that his P. verus should be considered a variety (i.e., synonymy) of P. cressoniellus. In later works, Cockerell (1919: 291; 1922: 6) still regarded calochorti as a variety or subspecific taxon, though also (i.e., Cockerell 1922: 7) questioned his synonymy of P. verus. Michener (1951: 1097) and Hurd (1979: 1851) accepted this synonymy as tentative (“?”). It is accepted here until subsequent work can refute this.
