The authors describe and illustrate Wardium longosacco (Joyeux & Baer, 1939) n. comb. (Cestoda: Hymenolepididae) collected from Charadrius marginatus from South Africa. The species with a strobila 7 cm long is characterised by one crown of ten aploparaksoid hooks 27-30 microm long, a simple genital atrium, a long evaginated cirrus (120 microm) which is glabrous, regularly cylindrical and slender (12-6.5 microm in diameters) and a simple, tubular, membranous vagina.
