Recognition. Most O. salebrosus are easily identifiable, except for female specimens from the southeastern United States where O. calcarifer and O. larvatus occur. In particular, small and abraded specimens require direct comparison with typical specimens. As in O. umbellae , reliable identification may be possible only when representative material of both sexes is available for study.

Distribution. Southern Canada and U.S.A. east of Rocky Mountains ( Fig. 36 ); one record from El Salvador suspect.

Nomenclatural notes. Odontocorynus salebrosus is morphologically variable. Casey (1892) initially distinguished three species based on pronotal and elytral punctation, dorsal vestiture, and size of the antennal club. My examination shows that the size of the scales decreases gradually across the Great Plains. The largest scales occur in the specimens from Colorado, at about 1500 m elevation. This type of variation has been documented for other scaled Baridinae, and regional gradients in temperature and humidity are thought to exert at least some influence ( Prena 2005: 47). The size of the club is variable in all subpopulations and seems to correlate with the length of the rostrum. Casey (1920) later recognized another 29 species in his series of O. salebrosus based on minuscule, taxonomically irrelevant differences. The lectotype designation is made to promote stability of the name for this common and repeatedly described species.
