Key to North American Elonus View in CoL View at ENA Species
1. Elytra uniformly dark brown with pattern of white setae consisting of a median wavy transverse stripe, two basal patches, and an apical band ( Figure 1i View FIGURE 1 )........................................................ E. nebulosus ( LeConte, 1875)
- Elytra bicolored: base entirely orange or with an orange blotch on each elytron, rest of the elytra brown to black ( Figure 1a–h View FIGURE 1 ).................................................................................................... 2
2. Short elytral pubescence between punctures dense, white, uniform, distinctly visible under lateral illumination ( Figure 4e–f View FIGURE 4 ) 3
- Short elytral pubescence between punctures sparser, darker, hardly visible, or limited to suture and a post-median stripe (Figure 4g –j)............................................................................................ 4
3. Elytra brown (except base), uniformly covered with long erected yellow setae ( Figure 4f View FIGURE 4 ). forelegs and midlegs reddish. Male mesotibiae strongly curved ( Figure 3l View FIGURE 3 )................................................. E. hesperus Werner, 1990
- Elytra black, long pale pubescence darker, only with white setae along suture ( Figure 4e View FIGURE 4 ). Male mesotibiae with moderate curvature ( Figure 3n View FIGURE 3 )............................................................... E. chisosensis Werner, 1992
4. Base of elytra marked with a solid, uninterrupted transverse orange stripe, only moderately narrower in scutellar region ( Figure 4c View FIGURE 4 )................................................................................................. 5
- Base of elytra marked with orange patches confined to humeral callus on each side; or orange markings forming a continuous stripe but with a strong constriction in the scutellar region ( Figure 4a, b View FIGURE 4 ).............................. E. gruberi n. sp.
5. Elytra with a post-median band of whitish pubescence, distinct under side illumination, composed of short recumbent setae interspersed between elytral punctation ( Figure 4h View FIGURE 4 , arrows). Male genitalia much longer than in other species ( Figure 2a View FIGURE 2 )................................................................................... E. basalis ( LeConte, 1855)
- Elytra without pattern of whitish pubescence................................................................ 6
6. Thorax and head half the width of elytra at their base; male mesotibiae with a kink ( Figure 3m View FIGURE 3 )... E. excavatus Werner, 1992
- Thorax and head at least 60% of elytra width at their base; male mesotibiae evenly curved......... E. simplex Werner, 1992
