Manfrin Multidisciplinaria (Ciencias Naturales y Exactas) aedeagus curvature morphometric Drosophila buzzatii cluster Drosophila serido and D. antonietae are sibling species belonging to the Drosophila buzzatii cluster. Morphologically,they can only be discriminated by quantitative traits. In this paper we analyze the length andequalized average curvature of four regions of the aedeagus of D. antonietae and D. serido. Specimens of D.serido and D. antonietae were classified correctly 96.74% of the time. Based only on the variable that mostcontributed to the discrimination of the groups (equalized average curvature of the arch IV of the aedeagus),we observed significant intraspecific morphological divergence in D. serido in relation to the D. antonietae, inagreement with other markers. The high morphological divergence in equalized average curvature of the archIV of the aedeagus shows that this region evolved faster than others, since the divergence of the two species.The importance of the present study to the understanding of the genetic basis that controls the formation ofthe aedeagus, in the species of the Drosophila buzzatii cluster, is discussed. 2006 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32778202 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.2 Vol.78 |
