Spasskii (1951)in a review <strong>of</strong> the Anoplocephalata utilised the termamphicyst first proposed by him (Spaskii, 1949) f<strong>or</strong>the larvae <strong>of</strong> linstowiids. Abuladze (1964) utilised avariety <strong>of</strong> terms f<strong>or</strong> taeniid larvae (then encompassingthe genera Cladotaenia and Paruterina, whichare currently placed in the Paruterinidae) (Table 2),using in addition to the traditional terms cysticercus,coenurus and echinococcus (= hydatid), those <strong>of</strong> strobilocercus,alveohydatid, armatetrathyridium andcladothyridium. To these have been added fimbriocercusby K<strong>or</strong>nyushin & Sharpilo (1986), hemistrobilocercusby Rausch (1981) and coenurostrobilocercusby Agapova (1950).
