Alloblackburneus aegrotus
(Horn, 1870)
Alloblackburneus aegrotus is a small dung beetle in the Scarabaeidae, Aphodiinae. The was described by Horn in 1870 and is currently placed in the Alloblackburneus, a group of aphodiine scarabs associated with decomposition. Records indicate a restricted distribution in the southeastern and mid-Atlantic United States. The species remains poorly documented in the scientific literature.
