ABSTRACT: We describe a new species of Dipetalonema occurring in the body cavity of Ateles chamek (Humboldt, 1812) from north-central Bolivia. Morphologic characters serving to separate Dipetalonema yatesi n. sp. from known forms include: a vagina vera within a simple tube and thin walls, the left spicule possesses a handle shorter than the lamina (ratio 2.7); the latter displays an anterior membranous alae similar in length to the terminal flagellum, a distal extremity of the left spicule within a simple hook and a membrane, phasmids at the basis of the lappets, and heterogeneous muscles occupying the whole cavity. Dipetalonema yatesi n. sp. can be separated from D. robini, D. gracile, and D. graciliformis, between other characters, in having a simple vagina vera instead of a sinuous one; and from D. caudispina and D. freitasi in having the lamina of the left spicule divided in a membranous alae and a terminal flagellum.
