Gnorimella maculosa
(Knoch, 1801)
Maculated Scarab
Gnorimella maculosa is a scarab beetle and the sole representative of its . It is characterized by spotted elytral patterning that gives the its name. The is associated with deciduous woodland in eastern North America. It is considered uncommon in collections and field observations.

Identification
The combination of spotted elytral patterning, moderate size (~15 mm), and association with eastern North American deciduous woodlands distinguishes this from similar cetoniine scarabs. It is the only species in the Gnorimella, which may be distinguished from related genera (e.g., Trichius) by subtle morphological characters of the scutellum and elytral , though precise diagnostic features are not detailed in available sources.
