During a study of Digenea of shorebirds from Galveston, Texas, 30% (30 of 9
9) of willets, Catoptrophorus semipalmatus (Charadriiformes), were found to
be infected with 55-405 Endocotyle bushi per infected host. Although the s
pecimens from Texas generally agree with E. bushi from Florida, specimens f
rom Texas are less elongated, have a more triangular to heart-shaped ovary,
have slightly larger eggs, and have a smaller seminal vesicle.
