A new species of Grillotia, G. gastrica n. sp., is described from the stomach musculature of the teleosts Upeneichthys lineatus (Bloch & Schneider) and Sillaginodes punctatus (Cuvier) from off Perth, Western Australia. The new species most closely resembles G. pristiophori Beveridge & Campbell, 2001 in having six hooks in each principal row of the metabasal tentacular armature but differs in having a smooth scolex tegument and in having a band of hooklets running the entire length of the external surface of the tentacle rather than diminishing in width to a single hooklet as occurs in G. pristiophori. Grillotia heptanchi (Vaullegeard, 1899) is redescribed and the details of the mature segment are described for the first time. Grillotia adenoplusius (Pintner, 1903) is redescribed from the type-specimens and is considered to be the larval stage of G. acanthoscolex Rees, 1944 (syns G. spinosissima Dollfus, 1969 and G. microthrix Dollfus, 1969). The adult of G. adenoplusius is also redescribed based on the types of G. spinosissima. The type-specimens of G. dolichocephala Guiart, 1935 and G. minor Guiart, 1935 were re-examined and G. minor is considered to be a synonym of G. dolichocephala as is G. meteori Palm & Schröder, 2001. Based on an examination of the type-specimens, G. scolecina (Rudolphi, 1819) is treated as a species inquirenda. A list is provided of the species currently placed in Grillotia.
