Resumen:
Based on a morphological approach, five species of cyclocoelids
(Digenea: Cyclocoelidae) are revised based on material from birds in
Mexico. The species studied are: Cyclocoelum cf. leidyi Harrah, 1922
from the black-necked stilt Himantopus mexicanus Muller
(Recurvirostridae); Cyclocoelum mutabile (Zeder, 1800) from the northern
jacana Jacana spinosa L. (Jacanidae) and the willet Tringa semipalmata
Gmelin (Scolopacidae); Cyclocoelum pseudomicrostomum Harrah, 1922 from
the American coot Fulica americana Gmelin (Rallidae); Selfcoelum
lamothei Blend & Dronen, 2008, from the long-billed curlew Numenius
americanus Bechstein (Scolopacidae); and Neohaematotrephus arayae
Zamparo, Brooks, Causey & Rodriguez, 2003 from J. spinosa. New
morphological data, illustrations and measurements are presented for
these trematodes. Three species, insufficiently described, i.e. C. cf.
leidyi, C. mutabile and C. pseudomicrostomum, are redescribed in detail.
Our results indicate morphological variation in some important features
used in the diagnosis of Cyclocoelum Brandes, 1892 (i.e. the presence or
absence of oral sucker, the position of the genital pore relative to the
pharynx, and the posterior extension of the uterus) and Selfcoelum
Dronen, Gardner & Jimenez, 2006 (i.e. anterior extension of vitelline
follicles). Finally, this study provides the first molecular data for
the large subunit of the ribosomal RNA (28S rRNA) gene for N. arayae.
