Dichelus acanthopus is a species of beetle of the family Scarabaeidae. It is found in South Africa (Western Cape).
Adults reach a length of about . They are similar to Dichelus dentipes, but the facies is not so robust, the colour of the pronotum is slightly greenish black, that of the elytra varies also from red-brown to fuscous, but instead of having appressed hairs they only have a band of greyish-white ones not closely set and often partly obliterated. The pygidium of the females has two hairless lateral patches like the female of Dichelus expansus.
