Psammomermis nitidulensis n. sp. (Nematoda : Mermithidae) is described from three species of sap beetles, Carpophilus bugubris Murray, C. antiquus Melsh and Colopterus truncatus (Randall) (Coleoptera: Nitidulidae) from Mason County, IL, USA. This mermithid differs from previously described members of the genus by the shape of the amphids and their association with the amphidial glands, the length, form and curvature of the spicules and the shape of the vagina vera and vagina uterina. A key to the species of Psammomatous is provided and the generic diagnosis is emended. This mermithid causes up to 80 % parasitism and death of the dusky sap beetle (C. lugubris), an important vector of mycotoxigenic fungi. Investigations are under way to determine the possibility of utilizing this mermithid for biological control of this insect pest.
