This paper aims to describe
Plenivitellinum kifi
n. gen., n. sp. (Digenea: Azygiidae) infecting the gastrointestinal tract of the African tigerfish,
Hydrocynus vittatus
Castelnau, 1861 (Characiformes: Alestidae) in the Kavango River, Namibia. We revise the diagnosis of Azygiidae Lühe, 1909 to accommodate this new species.
Methods
The worm was heat-killed, fixed in 10% neutral buffered formalin, stained in Van Cleave’s and Ehrlich’s hematoxylins, cleared in clove oil, and mounted on glass slide using Canada balsam.
Results
The new azygiid resembles species of
Otodistomum
Stafford, 1904 by having an elongate body, a ventral sucker that is wider than the oral sucker and that is in the anterior half of the body, a pre-testicular ovary, a uterus that primarily occupies the inter-caecal space between the ovary and the ventral sucker, and a vitellarium that is restricted to the hindbody and that is confluent posteriorly in the post-testicular region. The new genus differs from all species of Azygiidae by having the combination of a ventral sucker that is wider than the oral sucker (vs. narrower), an elongate prostatic sac that extends posteriad to near the posterior margin of the ventral sucker (vs. an ovoid prostatic sac that is wholly anterior to or slightly overlaps the anterior margin of the ventral sucker), a vitellarium that nearly fills the post-testicular space and that extends posteriad beyond the caecal tips (vs. a vitellarium that is separate posteriorly or that is restricted to the anterior half of the post-testicular space and does not extend posteriad beyond the caecal tips), and an I-shaped excretory bladder (vs. Y-shaped).
Conclusion
This study documents the first record of an azygiid from Africa and the first record of an azygiid infecting a characiform fish. |
