Abstract
The relatively small family Ochodaeidae Mulsant & Rey, 1871 of the superfamily Scarabaeoidea Latreille, 1802 includes 13 genera and about 100 extant species and subspecies belonging to two subfamilies (Scholtz et al. 1988, Paulsen 2007, Nikolajev 2009). One more subfamily, Cretochodaeinae Nikolajev, 1995, is known only from fossils (Nikolajev 1995). In total, there are four known fossil species of Ochodaeidae belonging to three genera in two different subfamilies (Nikolajev 2007, Krell 2007). The monotypic genus Mioochodaeus Nikolajev, 1995 has been described from Oligocene Rott (Germany). The genera Cretochodaeus Nikolajev, 1995 and Lithochodaeus Nikolajev, 2007 are known from the Lower Cretaceous Bon-Tsagan (Mongolia).
