U. kaniharensis (Gupta, 1958)

Syn. U. indica Siddiqi & Jairajpuri, 1962

Type host. Common greenshank, Tringa nebularia (Gunnerus) (Syn. Glottis nebularia Gunnerus ) ( Charadriiformes : Scolopacidae ).

Type locality. Kanihar, Allahabad District, India.

Additional host. Red-wattled lapwing, Vanellus indicus (Boddaert) (Syn. Lobivanellus indicus [Boddaert]) ( Charadriiformes : Charadriidae )— Siddiqi & Jairajpuri (1962).

Additional locality. Aligarh, Uttar Pradesh, India—Siddiqi & Jairajpuri (1962).

Remarks. Although originally described as Haematotrephus (Uvitellina) kaniharensis Gupta, 1958 , this species was considered to be a species of Uvitellina by Yamaguti (1971). It was considered to be a synonym of Cyclocoelum (H.) vanelli ( Rudolphi, 1819) (= Uvitellina vanelli [ Rudolphi, 1819]) by Dubois (1965). This species has a pretesticular ovary that forms a triangle with the testes (Haematotrephinae), the genital pore is postpharyngeal and the vitelline fields are confluent posteriorly, placing it in Uvitellina as suggested by Yamaguti (1971). Uvitellina kaniharensis is nearly identical to U. indica except that it has an unusual placement of the postpharyngeal genital pore as it was described and illustrated as being at the level of the intestinal bifurcation rather than being immediately posterior to the pharynx, as is more typical of cyclocoelids in this genus and subfamily, including U. indica . The length of the cirrus sac was not given in the original description of U. kaniharensis , but it appears to be about 350 in Fig. 1 of Gupta (1958a). In our opinion it is likely that the more posterior position of the genital pore than usual reported by Gupta (1958a) may be in error. Calculation of the length of the cirrus sac assuming that the genital pore is immediately postpharyngeal yields about 1,000 or 6% of the body length, which is the same as seen in U. indica . The length of the cirrus sac relative to body length in both species (2% vs 6%, respectively) is within the normal range of variability seen in cyclocoelids and both were described from Indian charadriiform birds; therefore, U. indica is synonymized herein with U. kaniharensis . Rudimentary oral sucker present—Gupta (1958a).
