Neoandracantha is a genus of parasitic worms from the phylum Acanthocephala. The genus was created in 2017 by Amin & Heckmann for the single species Neoandracantha peruensis. The genus was differentiated from the closely related genus Andracantha Schmidt, 1975 because members of Andracantha have anteriorly enlarged pear-shaped Corynosoma-like trunks, only two fields of anterior trunk spines with occasional genital spines, and bilateral or tandem testes, and because proboscides of species of Andracantha have considerably fewer hooks that gradually decrease in size posteriorly.
