Comments. The morphological characters observed in the specimens agree with the description given by Yamaguti (1971) of the genus Platynosomoides, i.e. long and narrow caeca, reaching far beyond middle of body; testes posterolateral to ventral sucker; median genital pore anterior to intestinal bifurcation; ovary posterior to testes and vitelline glands forming lateral bands starting at level of ventral sucker.

The genus Platynosomoides sp. has not been mentioned parasitizing sigmodontine rodents until today. However, it was recorded for Leopoldamys siporanus Thomas 1895 (Muridae) in Asia (Malaysia, Armenia and Daguestan, Russian Federation) and for Crocidura olivieri (Lesson 1827) (Soricidae) in Africa (Democratic Republic of the Congo) (Pojmańska 2008).

This is the first record of the genus for South America.
