Remarks: Ankylocythere talirotunda was synonymized with A. heterodonta in Hobbs (1966: 67, 69, 73). Ankylocythere heterodonta appears twice in the key on page 67 of that publication, the first time with the synonymy, the second time without. Cuellar, Garcia-Cuenca & Fontanillas (2002) reported Enthocytera heterodonta (erroneous spelling = Ankylocythere heterodonta ) on signal crayfish, Pacifastacus leniusculus, maintained in an aquaculture facility in Spain. Strangely, these authors appeared unsure if the ostracods were entocytherids or the free-living species, Eucypris virens , using the two names interchangeably in the tables and text. Ankylocythere heterodonta and Eucypris virens are highly differentiated morphologically, so this confusion seems unwarranted. Photo 6 (p. 971), identified as the latter species, is clearly a gravid female entocytherid, with three pairs of legs terminating in distinctive claws. Further, although species cannot be determined from the photo, it is highly unlikely that the entocytherids recovered from this study were Ankylocythere heterodonta ; to date, this species has not been reported from native or introduced signal crayfish.
