| Descripción: | During a study of the endohelminths of wading birds from the Texas Gulf coast, 12 specimens of an undescribed species of Patagifer Dietz, 1909 (Echinostomatidae: Nephrostominae) were collected from 2 of 8 white ibis, Eudocimus albus (Linnaeus) (Threskiornithidae), from the Galveston and Brazos County areas of Texas, USA. Patagifer lamothei n. sp. can be distinguished from P. bilobus (Rudolphi, 1819), P. brygooi Richard, 1964, P. consimilis Dietz, 1909, and P. fraternus Johnston, 1917, where the testes are close together (contiguous to nearly contiguous), the ovary is close to the anterior testis (a distance that is less than the length of the ovary), and the posttesticular space is less extensive, by having the testes separated from each other by a distance approximately equal to or greater than the length of the ovary, the ovary positioned about the length or longer of the ovary from the anterior testis, and by having a more extensive posttesticular space. In addition, the ovary of the new species is located just ahead of midbody rather than being at midbody, as is seen in P. bilobus, P. fraternus, and P. vioscai Lumsden, 1962, or below midbody, as is the case in P. brygooi and P. consimilis. The new species is most like P. simarai Nigam, 1944 in the similar distance between testes, position of the ovary, and the posttesticular space (30-36% of the body length). The new species differs from P. simarai by having a smaller body size, a smaller oral sucker and pharynx, a smaller acetabulum, ovary, testes, cirrus sac, and smaller spines on the margin of the collar, but larger corner spines, and the ovary of the new species is located immediately anterior to the midbody, while in P. simarai it is located well ahead of the midbody. |
