Levinseniella (Levinseniella) gavilanicola sp. nov. (Trematoda: Microphallidae) in the common black hawk Buteogallus anthracinus from Venezuela, and notes on its life cycle

A new species, Levinseniella (Levinseniella) gavilanicola sp. nov. (Trematoda: Microphallidae) is described from the small intestine, caecum and rectum of naturally infected common black hawk, Buteogallus anthracinus (type host), from El Paujil, Cajigal Municipality, Sucre State, Venezuela. The new species is placed into the group III according to Heard (1968) for possessing numerous accessory atrial sacs (7 or more) and presence of female pouch. The new species differs from other species of this group mainly in the number of atrial accessory sac (9 with sclerotized structures) and its arrangement in the wall of the genital atrium. Conspecific adults were obtained from laboratory reared chicks, a duckling, rats and mice after artificially feeding of crabs (Uca rapax) which served as the second intermediate host of this newly described trematode from La Ceiba and El Paujil in Sucre State.
