Chimaerula bonai sp. n. (Cestoda: Dilepididae) from the bare-faced ibis, Phimosus infuscatus (Lichtenstein) (Aves: Threskiornithidae) in Paraguay.
Chimaerula bonai sp. n. is described from the small intestine of Phimosus infuscatus (Lichtenstein) in Paraguay. The new species differs from the other two species of Chimaerula Bona, 1994, i.e., Chinmaerula woodlandi (Prudhoe, 1960) and Chinmaerula leonovi (Belogurov et Zueva, 1968), mainly by the intermediate number of rostellar hooks (30-34 compared to 42-46 in the former and 20-22 in the latter), longer rostellar hooks (31-34 microm versus 26 microm and 19-21 microm, respectively), shorter cirrus sac (58-82 microm versus 158-201 microm and 134-183 microm, respectively) and the absence of rosethorn spines in the cirrus armament. Modifications in the generic diagnosis of Chimaerula are proposed in order to conform it with some peculiarities of the new species (i.e., the relatively small and thin cirrus, the absence of rosethorn spines in its armament and the small cirrus sac).
