Spring-active Arizona specimens identified as Sphaenothecus bilineatus (Gory, 1831) were determined to represent another species, S. cylindricollis (Casey, 1924), which had been a synonym and is herein reinstated as a valid species. A diagnosis of S. cylindricollis is presented with morphological characters photographed, discussed, and compared to S. bilineatus. Specimen label data from institutional and private collections are provided for S. cylindricollis.
