Deltochilum gibbosum, the humpback dung beetle, is a species of dung beetle in the family Scarabaeidae. It is a member of subgenus Hybomidium Shipp, 1897 and is found in the southeastern United States. A variety described by Henry Walter Bates in 1887, D. gibbosum var. sublaeve, has been classified as a separate species D. sublaeve by González-Alvarado and Vaz-de-Mello. The same authors regard D. gibbosum subsp. panamensis Howden, 1966 as a separate species D. panamensis. Wikipedia →
