Última Morphology of the Middle Ear in Three Species of Armadillos (Dasypodidae, Xenarthra) from Argentina International Journal of Morphology Sidorkewicj,Nora S; Casanave,Emma B. Middle ears of adult Chaetophractus villosus, C. vellerosus and Zaedyus pichiy were studied for qualitative and quantitative comparisons. A great similarity in the overall shape of the middle ear structures was observed in the three species. The well-developed auditory bulla was formed by the intimate fusion of the tympanic and entotympanic. Internally, a recessus meatus and a wide epitympanic recess extending dorsally into an epitympanic sinus were recognized. The petrosal promontorium, nearly triangular, was the most salient feature in the tympanic cavity. The auditory ossicles corresponded to the transitional middle ear type. The m. tensor tympani and the m. stapedius were conspicuous. The lack of a stapedial artery was confirmed in all cases. The...

The morphology and relative size of the tympanic bulla of three species of dasypodids from Argentina, Chaetophractus villosus, C. vellerosus and Zaedyus pichiy, were studied. The bulla was observed to be morphologically similar and evidently hypertrophied in the three species. The degree of hypertrophy was higher in C. vellerosus and C. villosus than in Z pichiy. By means of ANCOVA it was clear that, although C. villosus has a bigger skull than C. vellerosus, the relative size of their tympanic cavity was similar in both species. On the other hand, the skull of C. vellerosus and Z pichiy are of similar size but the bulla was relatively shorter in the later Tipo: Journal article Palavras-chave: Chaetophractus villosus; Chaetophractus vellerosus; Zaedyus pichiy; Middle ear; Tympanic bulla.

A Light and Electron Microscopic Study International Journal of Morphology Galíndez,Elena Juana; Estecondo,Silvia; Casanave,Emma B.. The spleen is a multifunctional organ. Its microarchitecture reflects so well the phylogeny as the adaptation to niche in each animal group and inclusive in each species. Armadillos, as ancient and isolated mammals, show a mixture of ancestral and modern structures. In this work the microanatomy and cytology of the spleen of the little hairy armadillo Chaetophractus vellerosus was studied. The material was fixed and processed according to the typical methods for light and electron microscopy. Results show a cumulative medium sized spleen with the typical pulps. The white pulp is well developed but less defined than in other armadillos. The presence of follicular-dendritic-like cells and interdigitant dendritic-like cells, as well as clusters of...

Ezquiaga,María C.; Lareschi,Marcela; Abba,Agustín M.; Navone,Graciela T.. Los estudios realizados sobre las pulgas parásitas de xenartros argentinos son escasos. Esta contribución da a conocer nuevas especies de pulgas que parasitan a dasipódidos en la provincia de Buenos Aires, Argentina. Polygenis (Polygenis) platensis (Rhopalopsyllidae) se halló en Chaetophractus vellerosus, y Tunga penetrans (Tungidae) en Chaetophractus villosus y Dasypus hybridus. El hallazgo de P. (P.) platensis constituye el primer registro para dasipódidos. Se amplió la distribución conocida de T. penetrans y se citan dos nuevas asociaciones parásito-hospedador.
