| Sumario: | Travassostrongylus yungaensis n. sp. and Hoineffia simplicispicula n. sp., belonging to the family Viannaiidae and collected from the intestine of Thylamys venustus cinderellus and Lutreolina crassicaudata from Tucamán and Salta, Argentina, are described. T. yungaensis n. sp. differs from T. tourei, T. quintus, T. quatuor and T. paraquintus because it possesses a well-developed dorsal lobe of the caudal bursa without accessory rays. Furthermore, the absence of a telamon distinguishes it from T. quatuor and T. quintus. H. simplicispicula differs from H. cayennensis in its shorter cephalic vesicle, simple spicular structure and gubernaculum, the absence of accessory pieces in the caudal extremity of the female and the lack of ornamentation between rays 2 and 6 and the dorsal lobe of the male. The distribution of the parasites along the intestine of the host suggest that both genera may co-exist, sharing the same ecological habitat but each having its preferential microbiotope. © 1991 Kluwer Academic Publishers. |
