Artigasia milerai sp. nov. (Oxyurida: Hystrignathidae) is described from the gut caeca of Passalus interstitialis Escholtz, 1829 (Coleoptera: Passalidae) from Escaleras de Jaruco, La Habana province, Cuba (type locality) and El Pan de Matanzas, Matanzas province, Cuba. It differs from A. ensicrinata (Hunt, 1981), A. monodelpha (Travassos & Kloss, 1958) and A. pauliani Théodoridès, 1955 by having ridged eggs and a comparatively shorter tail. It also differs from A. monodelpha and A. pauliani by having a comparatively shorter esophagus, the vulva being slightly more posterior, and the extension of the cervical spines. It is close to A. ankaratrae Van Waerebeke, 1973 but can be differentiated by a stouter body, a comparatively shorter oesophagus and and the extension of the lateral alae.
