Taxonomic revision of species of Haematoloechus Looss, 1899 (Digenea: Plagiorchioidea), with molecular phylogenetic analysis and the description of three new species from Mexico

“…), and in the distribution of the vitellaria; while they are limited to two groups, one anterior to the ventral sucker and other posterior to the testes in the South American species, they are distributed continuously extending asymmetrically, from the region anterior to the ventral sucker to the level of the posterior testis on the ovarian side of the body, and halfway between the posterior testis and the posterior end on the side opposite to the ovary in H. veracruzanus n. sp. (Travassos & Darriba 1930). It differs from H. complexus and H. elongatus in the arrangement of the uterine loops.…”

“…It differs from H. illimis and H. dollfusinum in the shape of the ovary, which is lobed in those species (Caballero 1942a) and oval in H. caballeroi. The presence of diagonal uterine loops directed anteriorly at the posterior end of the body differentiates H. caballeroi from H. humboldtensis, H. longicollum, H. parcivitellarius, and H. pulcher, in which the diagonal uterine loops are either absent or directed posteriorly (Caballero 1942b;Zamparo et al 2011; (Travassos & Darriba 1930;Caballero & Sokoloff 1934;. It also differs from H. fuelleborni in the distribution of the vitellaria; while they are limited to two groups, one anterior to the ventral sucker and other posterior to the testes in the South American species, they are distributed continuously from the anterior region of the ventral sucker to the posterior region of the testes in H. caballeroi.…”
