Explanation of Names
Author is MacLeay 1819, who originally described as its own family, Rutelidae, now regarded as a subfamily of the Scarabaeidae. Name from genus Rutela (Latreille, 1817), an error for Latin rutila (masculine rutilus), meaning red (1).
Numbers
Worldwide, over 4,100 species.
Identification
Elongated to oval, often shiny, scarabs. Distinctive for having unequal, independently moveable tarsal claws, esp. on hind legs (2). Other typical (but not necessarily diagnostic) characters include:
middle tibiae with two apical spurs
pygidium exposed, not completely covered by elytra
scutellum is exposed, not covered by elytra
antennae with 9-10 segments, last three forming a club
