The objective of this study is to describe this species. The new species differs from other known species of Haematoloechus by the combination of the following characters: spindle shaped body, oral sucker/acetabulum ratio 1:0.31, longitudinal extracecal uterine loops extending to the level of posterior testis, ovary irregular, lobed and testes elongate, lobed.]]></p></abstract>

El objetivo de este trabajo es describir esta especie. La especie nueva difiere de las conocidas de Haematoloechus por la combinación de los siguientes caracteres: cuerpo en forma de huso, relación ventosa oral/acetábulo 1:0.31, asas uterinas longitudinales extracecales extendiéndose hasta el nivel del testículo posterior, ovario irregular, lobulado y testículos alargados, lobulados.]]></p></abstract>
