| Summary: | The genus <i>Ancistrohaptor</i> was proposed to accommodate monopisthocotylans flatworms parasitic on the gills of species of the genus <i>Triportheus</i> in Manaus, Amazonas state, Brazil. Its main characteristics are (a) an accessory piece of the male copulatory organ composed of two distinct parts; (b) dextral or dextroventral vaginal openings; and (c) large ventral anchors with elongated shafts. A new species of <i>Ancistrohaptor</i> was found to parasitize the gills of <i>Triportheus signatus</i> collected from the Salgado River, Ceará State, Brazil. A new species of Monopisthocotyla was collected and described. <i>Ancistrohaptor forficata</i> sp. n. is primarily characterized by having a male copulatory organ with less than one turn, the presence of an articulated accessory piece with a concave rod-shaped termination, and a free accessory piece that is clamp shaped and bifurcated, as well as a dorsal bar with shading present in its medial part. This is the fourth species description of the genus <i>Ancistrohaptor</i> for fish of the genus <i>Triportheus</i> and the first record for <i>T. signatus</i> and the aquatic ecosystems of the Caatinga domain. |
