Resumen:
Patagifer Dietz, 1909 is a small genus of echinostomatids, with 12
recognized species, mostly parasitising threskiornithid birds,
distributed worldwide. In the current research, adult specimens of the
type species, Patagifer bilobus (Rudolphi, 1819) Dietz, 1909 from the
white faced ibis (Plegadis chihi) and white ibis (Eudocimus albus) were
re-described, providing new metrical data for the number of head collar
spines. Those specimens were recorded from eight localities in Mexico
and compared morphologically with specimens previously identified as
Patagifer lamothei. A total of 19 specimens identified as P. bilobus
including two hologenophores were sequenced with three molecular
markers: domains D1-D3 of the large subunit (LSU), the internal
transcribed spacer (ITS1, ITS2) plus 5.8S from the nuclear rDNA, and
nicotinamide adenine dinucleotide dehydrogenase subunit 1 (nad1) from
mitochondrial DNA. The new sequences were aligned with other sequences
of Patagifer spp., downloaded from GenBank. Phylogenetic trees inferred
from each data set, placed all the specimens in a Glade, confirming that
the isolates belonged to the same species. The morphological examination
of specimens previously identified as P. lamothei by Ortega-Olivares MP,
Hernandez-Mena D1, Perez-Ponce de Leon G, Garcia-Varela M (2011)
Helminths of the white ibis, Eudocimus albus (Ayes Therskiornithidae) in
Mexico. (Zootaxa 3088, 15-26. 10.11646/zootaxa.3088.1.2) and in
combination with molecular data confirms that those specimens should be
reassigned to P. bilobus. In addition, this is the first study in P.
bilobus using an integrative taxonomy approach.
