Comments. The morphological characters observed in the specimens agree with the original description given by Digiani et al.

Digiani et al. (2012) gathered material of S. angouya from four localities: Reserva Privada de Vida Silvestre Urugua-í, Depto. General Manuel Belgrano; Puerto Península, Parque Nacional Iguazú, Depto. Iguazú; Refugio Moconá, A ° Oveja Negra and Ruta 2, Reserva de la Biósfera Yabotí, Depto.

This is the first record of G. ulysi for E. russatus, enlarging the geographical and host range of the species.
