Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Note

The following key is based on characters of adult beetles. The text was first published in Bell and Bell (1991).

1.      Mentum separated laterally from gena by a cleft (Figure 1).

2(1).   Minor setae of outer antennal segments in broad bands 
        (Figure 3); pronotum with paramedian grooves narrow, 
        complete; median groove with anterior, posterior pits 
        (Figure 4); pronotum much narrower than elytra; elytral 
        humerus not dentate. .............................Leoglymmiina

2'.     Minor setae of outer antennal segments forming subapical 
        ring on each segment (Figure 5); pronotum with rounded basal 
        impressions, without paramedian grooves; median groove 
        linear, not expanded at either end to form anterior, 
        posterior median pits (Figure 6); pronotum broad, almost as 
        wide as elytra; elytral humerus dentate. ......Sloanoglymmiina

3(1).   Minor setae of outer antennal segments forming a tuft on 
        ventral side of segment (Figure 7) or minor setae entirely 
        absent (except apical segment) .....................Clinidiina

3'.     Minor setae of each outer antennal segment forming a 
        subapical ring (usually only one seta in width, Figure 8).

4(3).   Median lobe of head elongate, extending to neck 
        constriction, widely separating temporal lobes (Figure 9).

        (Figure 10). ................................................5

5(4).   Median lobe not defined; frontal pit round, porelike; 
        frontal grooves absent or barely suggested (Figure 11) 
        (Africa, South America, New Zealand). ...............Dhysorina

5'.     Median lobe defined by frontal grooves, usually deep (Figure 
        12). ........................................................6

6(5).   Frontal pit absent; median grooves very shallow, meeting at 
        neck constriction (Figure 13) (South Africa). ......Medisorina

6'.     Frontal pit present, overhung by tip of median lobe; frontal 
        grooves deep in most species; if grooves are very shallow, 
        then frontal pit is large, crescentic (Figure 14).
