Biología reproductiva y desarrollo del esqueleto de Polychrus acutirostris (Iguania, Polychrotidae)

Abstract

Se describe el desarrollo del esqueleto craneal y poscraneal del Polychrus acutirostris procedente de una población del nordeste de la provincia de Formosa, (Argentina.) y se comparan con Liolaemus scapularis, L. quilmes y Tropidurus etheridgei del norte de Argentina. Las observaciones se basaron en 16 embriones y un recién nacido. Entre los rasgos más interesantes del desarrollo del condrocráneo y osteocráneo se encuentra la ausencia de taenia marginalis sobre la fenestra epióptica y la fusión de las fenestras proótica y metóptica, reducción de los cartílagos orbitotemporales y osificación temprana del pterigoides. Entre los eventos poscraneales se destaca la osificación temprana de las clavículas, osificación asincrónica de los elementos de ambas cinturas y sincrónica de los elementos estilopodiales y zeugopodiales en ambos miembros. Adicionalmente se compararon datos de la biología reproductiva de Polychrus acutirostris de las poblaciones de Formosa (Argentina) con las del Cerrado (Brasil).
