Resumen:
This paper describes Diegloglossidium maradonai n. g., n. sp. a parasite
of the intestine of Hoplosternum littorale (Hancock) from La Plata River
basin. The new genus is morphologically similar to members of
Alloglossidiidae and Macroderoidiidae although they also share some
traits observed in both families. Those families can be differentiated
from each other by the combination of morphological features, including
the density and distribution of the tegumental spines, the distribution
of the vitelline follicles and the extent of the post-testicular space.
The molecular analyses based on the large subunit of the ribosomal RNA
gene, and the internal transcribed spacer (ITS) regions including ITS1,
5.8S and ITS2 unequivocally place the new genus in the family
Alloglossidiidae which is amended based on new observed features.
Diegoglossidium n. g. is characterized by a combination of
characteristics, being most notably the presence of a deeply lobed
ovary. Lastly, the geographical distribution and host associations of
the two closely related Neotropical genera of Alloglossidiidae:
Magnivitellinum and Diegoglossidium are discussed, and the host and
distribution range of Magnivitellinum saltaensis is expanded into
Argentina.
