Anenterotrema is a small genus of dicrocoeliids (Digenea: Dicrocoeliidae) containing 6 species found in Neotropical bats. Members of this genus are characterized by the lack of digestive system organs and, unlike the majority of dicrocoeliids, parasitize the intestine of their definitive hosts. In this study, we have morphologically examined newly collected specimens belonging to four species of Anenterotrema from Brazil, Ecuador, and Panama. Based on the data in original descriptions and our analysis of quality new specimens, we resurrected Anenterotrema freitasi, previously synonymized with A. eduardocaballeroi. We also described a new species of Anenterotrema from Molossus molossus in the Brazilian Amazon. The new species differs from congeners in several morphological features, most prominently in the size and structure of its highly muscular, protuberant ventral sucker. It is also characterized by the lack of the semi-circular thickening of the tegument around the oral sucker typical for some members of the genus. We used partial DNA sequences of the large ribosomal subunit gene (28S) and mitochondrial cytochrome c oxidase subunit 1 gene (cox1) to test the monophyly of Anenterotrema, and study the interrelationships and determine the inter- and intraspecific variation of three Anenterotrema spp. collected from different bat species in Brazil, Ecuador and Panama. |
