Genus Scaphisoma Leach, 1815

Remarks: This genus comprises less species in North America that Baeocera , while the opposite is in the Old World. 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 .
