Two new species of Maritrema (Trematoda: Microphallidae) from the Pacific Coast of North America
Maritrema pacifica n. sp. has an incomplete posterior ring of vitellaria, a spiny cirrus, a trilobed ovary, and a well-differentiated metraterm. It differs from M. patulus Coil, 1955 in the larger body, longer esophagus, round rather than slit-like genital pore, and larger eggs. It differs from M. i...
