Neoserica benigna is a species of beetle of the family Scarabaeidae. It is found in South Africa (KwaZulu-Natal).
Adults reach a length of about 8 mm. Adults are just as dark brown as Neoserica barbata, and very like this species also in the elongate form, but more reddish-brown on the under side. The elytra are irregularly punctate in the striae, the interspaces lightly raised, with tiny bristles in the punctures, and more distinct white bristles in rows.
