To date, 23 species of Scaphisoma have been reported from the USA ( Newton et al., 2001 ), including S. americanum ( Löbl, 1987 ) originally placed in the subsequently synonymized Caryoscapha (see Leschen & Löbl, 2005 ). The following four species have been listed from Arizona in Löbl (2018) : S. commune Löbl, 1997 based on probably a mislabelled specimen of S. convexum Say, 1825 (see Casey, 1893 ), S. desertorum Casey, 1893 , S. pusillum LeConte, 1860 , and S. rufulum LeConte, 1860 .
