A new species of P hallangothelphusa Pretzmann, 1965, is described from the foothills of the Serrania Yariguies, Santander Department, Magdalena river basin, Colombia. The number of the species increases to five: P . dispar (Zimmer, 1912), P . magdalenensis Campos, 1998, P . juansei Campos, 2010, P . martensis Cardona & Campos, 2012, and P. tangerina n. sp. The new species is distinguished from its congeners mainly by the morphology of the first male gonopod, particularly by the shapes of the mesial and lateral processes, and the surface and outline form of the apex.
