Genus Synetocephalus Fall, 1910
Synetocephalus Fall, 1910: 146 (type species Synetocephalus autumnalis Fall, 1910, by monotypy).
Remarks
This genus contains eleven described species. They occur in the western United States and northwestern Mexico. See Fig. 116 for a habitus illustration. See Wilcox (1965) for a key that includes most of the described species. Only two species are missing from that key: S. wallacei (Wilcox, 1965) that was transferred from Pseudoluperus by Riley et al. 2002b), and a new species was described by Gilbert & Clark (2012).
