Resumen:
A new species of microphallid trematode was collected from the intestine
of the yellow-crowned night heron Nyctanassa violacea (L.)
(Pelecaniformes: Ardeidae) from Veracruz, Mexico. Maritrema kostadinovae
n. sp. differs distinctly from other members of Maritrema Nicoll, 1907
from the Americas by its smaller body size (262-435 x 242-363 mu m), the
extension of caeca (reaching to anterior level of ventral sucker), the
size and shape of the cirrus (short, tubular and unarmed) and metraterm
(simple and thin-walled), the position of the genital pore
(sinistrolateral to ventral sucker) and the arrangement of the
vitellaria (horseshoe-shaped with posteriorly directed opening). Maximum
likelihood and Bayesian inference analyses, based on partial 28S rDNA
sequences, depicted M. kostadinovae n. sp. within the genus Maritrema
with strong support. The new species is in a sister position to other
available members of Maritrema, except for M. subdolum Jagerskiold, 1909
that branches as the early divergent species in the Maritrema clade. The
new species is the third species of Maritrema described from birds in
Mexico. Comparative morphometric data for Maritrema taxa from birds and
mammals from the Americas is provided.
