Abstract

During the helminthic investigation of wading birds of Sindh, the Black-winged stilt, Himantopus himantopus (L., 1758) (Charadriiformes: Recurvirostridae) was examined to update the trematode fauna of Sindh, Pakistan. The trematodes worms were recovered from the body cavity of the host and identified as species of the genus Uvitellina Witenberg, 1923; total 22 birds were examined in which 19 birds were found infected with 56 specimens of three species under the genus Uvitellina. The three species were identified as U. vanelli (Rudolphi, 1819) and U. pseudocotylea Witenberg, 1923 as new host and country record, and U. sindhiensis was introduced as species novum, which was named on its type locality, Sindh province, Pakistan.
