Updated keys to the genera in the subfamilies of Cyclocoelidae Stossich, 1902, including a reconsideration of species assignments, species keys and the proposal of a new genus in Szidatitreminae Dronen, 2007 Author Dronen, Norman O.

Type host. White-eyed buzzard, Butastur teesa (Franklin) (Falconiformes: Accipitridae ). Type locality. Sindh, Pakistan . Remarks. The description of Uvitellina teesae Dharejo, Bilques & Khan, 2007 by Dharejo et al . (2007) is incomplete and neither the description nor the illustration provides the characteristics necessary to place this species in a genus. The pretesticular ovary forms a triangle with the testes (Haematotrephinae), the genital pore is postpharyngeal (“close to the intestinal bifurcation”) and the testes are diagonal. If the vitelline fields are confluent posteriorly then this species would be assigned to Uvitellina ; however, if they are not confluent posteriorly this species would be assigned to Haematotrephus . Dharejo et al . (2007) described the vitelline fields as “vitellarium extracecal and occupying lateral fields” suggesting that they are not confluent posteriorly. The illustration of the vitelline field (one side only) is unclear in Fig. 1 of the original description; however, it appears to range from about a fourth of the body length posteriorly to about two thirds of the body length, and would be considered to be not confluent, placing this species in Haematotrephus . Note that this species was reported from an unusual bird host, the white-eyed buzzard; the only cyclocoelid definitive host known from the Falconiformes. Rudimentary oral sucker present—Dharejo et al . (2007).
