Velez, I. & V.E. Thatcher: Five species of Lecithodendriidae (Trematoda) in bats from Colombia, including three new genera. Three new neotropical genera and species of Lecithodendriidae (Trematoda) are described from Colombian bats. Sturniratrema umbilicata gen. et sp. nov. from Sturnira lilium differs from other genera in having an oval ventral depression, a dorso-ventrally curved cirrus and a genital pore lateral to the acetabulum. Chiropterotrema antioquiense gen. et sp. nov. from Carollia perspicillata is distinguished by having the acetabulum within a triangular ventral pit as well as an separation between the the male and female genital pores. Topsiturvitrema verticalia gen. et sp. nov. from Carollia perspicillata has a different orientation of the body, being nearly spherical but somewhat flatened in an anterior-posterior direction. This genus also has a deep ventral cleft separating two ventral lobes which are filled with eggs. Castroia silvai Travassos, 1928, is also reported from Anoura caudifer and Peropteryx macrotis. The first of these represents a new host record for the species. Addiotionally, Limatulum gastroides Macy, 1935, is reported from Lonchophyla robusta wich is another new host record.
