- Selfcoelum lamothei n. sp. (Digenea: Cyclocoelidae: Cyclocoelinae) from the air sacs of the long-billed curlew, Numenius americanus (Scolopacidae), from the Galveston, Texas area, USA Charles K. Blend Norman O. Dronen Biología sp comb Texas Curlew Galveston Fourteen specimens of a new species of cyclocoelid, Selfcoelum lamothei n. sp. (Digenea: Cyclocoelidae: Cyclocoelinae), from the air sacs of a long-billed curlew, Numenius americanus Bechstein (Scolopacidae), collected from the Galveston area, Galveston County, Texas, USA, were examined. The new species has an intertesticular ovary that forms a triangle with the testes, placing it in Cyclocoelinae Stossich, 1902. The new species is most similar to Selfcoelum capellum (Khan, 1935) n. comb., but differs from this species by lacking an oral sucker and by having a somewhat larger ovary, larger testes, a smaller posttesticular space, a larger cirrus sac, larger eggs, and the vitelline follicles of S. lamothei n. sp. are more bulky making the vitelline fi elds more laterally extensive, and more anteriorly distributed (reaching anteriorly to the level of the pharynx compared to the level of the cecal bifurcation) than those of S. capellum. The new species can be distinguished from the 2 species currently assigned to Selfcoelum Dronen, Gardner and Jiménez, 2006, S. brasilianum (Stossich, 1902) and S. limnodromi Dronen, Gardner and Jiménez, 2006, by having an intercecal uterus rather than having uterine loops that overreach the ceca laterally. The genus Selfcoelum should be emended to include those species where the uterus is either intercecal or where the uterine loops overreach the ceca laterally and those species with or without an oral sucker. 2008 artículo científico 1870-3453 https://www.redalyc.org/articulo.oa?id=42558786010 en http://www.redalyc.org/revista.oa?id=425 Revista Mexicana de Biodiversidad application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Biodiversidad (México) Num.1 Vol.79
