Martin, Storm B., Cutmore, Scott C., Ward, Selina & Cribb, Thomas H., 2017, An updated concept and revised composition for Hamacreadium Linton, 1910 (Opecoelidae: Plagioporinae) clarifies a previously obscured pattern of host-specificity among species, Zootaxa 4254 (2), pp. 151-187 : 174

Eucreadium cameronii Gupta 1963

Synonyms: Hamacreadium manteri Gupta & Kumari, 1974 n . syn.

Records. From Securicula gora (Hamilton) [as Chela gora (Hamilton) ] ( Cypriniformes : Cyprinidae ) from Varanasi, Uttar Pradesh, India by Gupta (1963). From S. gora [as Chela gora ] from Kanpur, Uttar Pradesh, India by Gupta & Govind (1983). From the large razorbelly minnow, Salmophasia bacaila (Hamilton) [as Chela bacaila (Hamilton) ] ( Cyprinidae ) and Se. gora [as Chela gora ] from Ludhiana and Rupnagar, Punjab, India by Gupta & Kumari (1974) as H. manteri .

Remarks. The specimens described by Gupta & Kumari (1974) clearly do not belong in Hamacreadium because the genital pore is medial, the ovary is entire, the vitelline field reaches to the oral sucker and the hosts are freshwater fishes. The oral and ventral suckers are also of similar size, suggesting a species of Eucreadium, three species of which have been proposed from cyprinids in India: E. cameronii, Eucreadium hemlatae Gupta & Govind, 1983 and Eucreadium jhingrani Srivistava & Singh, 1967. The description of Gupta & Kumari (1974) is indistinguishable from E. cameronii and so H. manteri is synonymised with that species here.
